how big was the universe before the big bang

If you can tell Einsteins equations what all the different types of matter and energy in the Universe are, and how they move and evolve over time, those same equations can tell you how space will curve and evolve including by expanding or contracting at any point in the past or future. As time continues to march forward, well be able to see even farther away, as light thats still on its way eventually reaches us. Surprises me how any real theories can explain the universe before it became the universe. As you can see, there are a series of remarkable milestones. Unique Fingerprints of Alternatives to Inflation in the Primordial Power Spectrum by Xingang Chen, Abraham Loeb and Zhong-Zhi Xianyu, 28 March 2019, Physical Review Letters.DOI: 10.1103/PhysRevLett.122.121301arXiv: 1809.02603, Quantum primordial standard clocks by Xingang Chen, Mohammad Hossein Namjoo and Yi Wang, 4 February 2016, Journal of Cosmology and Astroparticle Physics.DOI: 10.1088/1475-7516/2016/02/013arXiv: 1509.03930. About 15 years ago, we could only constrain the energy-equivalent of that temperature to be about 4 1016 GeV, but subsequent superior measurements have lowered that value substantially. With Brian Cox, Kimberly Arcand, Larry Gladney, Carole Haswell. I should add, that said it is nice if the fringe group come up with better experiments. What Came BEFORE The Big Bang - ExplainedToday I explained what came before the big bang, or how did something come from nothing, if there even was a nothing. The Universe we have is not only governed by Einsteins General Relativity, but a special case of it: where the Universe is both: If the Universe is the same in terms of matter-and-energy in all places and in all directions, then we can derive a Universe that must either expand or contract. As Einstein wrote: For we convinced physicists, the distinction between past, present, and future is only a stubbornly persistent illusion. Ha ha. U.S. Marine Corps photo by Gunnery Sgt. Just as a radioactive particle sends out alpha and beta particles as it decays, a parent universe could do the same thing, but sending out Big Bangs that create new universes instead of particles (via Live Science). But what if we went all the way back: back to the very beginning, and the very first moment of the hot Big Bang itself? You dont need an observatory like LIGO to see it; it would imprint itself in the polarization signal on the cosmic microwave background. It is the least likely of all possibilities. One can continue to extrapolate this forwards and backwards in time, but only so long as the components of energy that exist today didn't have transitional points. If youre the next Einstein, why are you well known and why dont you know how to form complete sentences with correct grammar? "Inflation tells us that the period of time before the Big Bang was extremely cold, almost at absolute . Download it once and read it on your Kindle device, PC, phones or tablets. This transformation from inflationary energy into matter and radiation represents an abrupt change in the expansion and properties of the Universe. But has it been been conclusively proved yet? Opinions expressed by Forbes Contributors are their own. One theory for how our universe will end is known as the Big Crunch. To help decide between inflation and these other ideas, the issue of falsifiability that is, whether a theory can be tested to potentially show it is false has inevitably arisen. It was a chaotic, swirling mass of particles and energy, constantly churning and moving. You may opt-out by. But early on, for the first ~10,000 years after the Big Bang or so, radiation was the dominant component of the Universe, and arguably, the only one that mattered. Their paper on the subject, published in 2004, suggested that our universe could have been created as a result of a piece of space-time splitting from a parent universe (via Cornell University). Dark matter? Some scientists have theorized that if the Big Crunch were to occur, it is possible that all that matter being smashed into one place could create enough energy to trigger a second Big Bang, restarting the universe from scratch (via Space.com). Please keep your theology out of this science discussion. According to NASA, the James Webb telescope, launched December 25, 2021 (per Space.com), will be able to see as far back as just 100 million to 250 million years after the Big Bang. You cant have it both ways. All items ship Mon-Fri International Buyers - Please Note: Import duties, taxes, and charges are not included in the item price or shipping cost. concentration of galaxies many hundreds of millions of light years away. Bottom: Inflation. If the best models of inflation are right, somewhere between the size of a human head and a skyscraper-filled city block. The idea that we are bouncing back and forth between bangs and crunches is not the only theory that could explain what took place before the Big Bang. We can only run the clock back a certain, finite amount until the story changes, with todays observable Universe and all the matter and energy within it allowed to be no smaller than the wingspan of a typical human teenager. The creation of something new is not accomplished by the intellect but by the play instinct acting from inner necessity. The size of the Universe (y-axis, in light years). In addition to new discoveries like gravitational waves, newer technology will also be able to help scientists get a better idea of how things may have worked during the first moments of our universe. versus the age of the Universe (x-axis, in years) on logarithmic scales. And its very conceivable that the entire Universe is substantially larger than that, but well never know by how much, since all we can observe is a lower limit on the true size of the actual Universe. Fortunately, theres a straightforward relationship between how early we go in the early Universe and how hot the Universe could have gotten in its earliest, radiation-dominated phase. The notion that everything came into existence in a single moment for no discernable reason is the ultimate test for credulity. Astronomers call these three classes effects evolution (if older/more distant objects are intrinsically different), environmental (if the locations of these objects differ significantly from where we think they are) and extinction (if something like dust blocks the light) effects, in addition to the effects we may not even know are at play. Truth be told an explosion didn't start the universe. It was born. My, my, my. Today, 13.8 billion years after the Big Bang, the Universe is 46.1 billion light-years in radius in all directions from our vantage point. They are all present today, and they were all present at least, we think they were all present right from the start of the hot Big Bang. If we imagine all of the information we learned so far about what happened before the Big Bang is in a roll of film frames, then the standard clock tells us how these frames should be played, Chen explained. where it became cold and empty, except for the energy inherent to the inflationary field. Its ####ing horse####! and then, at some moment, after expanding like this for an indeterminate, possibly very long or even infinite, amount of time, that inflationary field decayed. Stepping backwards: And yet, theres a cutoff to how far back we can go in time, which corresponds to the highest temperature the Universe could have ever reached. Around 13.82 billion years ago, matter, energy, space - and time - erupted into being in a fireball called the Big Bang. The Universe Before the Big Bang: Cosmology and String Theory by Gasperini: Used. And these theories are impossible to verify for certain without a time machine or magical crystal ball. When we look out at the distant galaxies, as far as our telescopes can view, there are some things that areeasy to measure, including: These are very important, because if we know what the speed of light is (one of the few things we know exactly), and how intrinsically either bright or big the object were looking at is (which wethink we know; more in a second), then we can use this information all together to know how far away any object actually is. If you know what your Universe is made out of, which is: you can use this information to extrapolatebackwards in time to any point in the Universes past, and find out both what the different mixes of energy density were back then, as well as how big it was at any point along the way. At some point around 200 to 500 million years, the earliest generations of stars and galaxies form (exact timings are still being researched), and early large structures gradually emerge, drawn to the foam-like dark matter filaments which have already begun to draw together throughout the universe. And because theres a very well-specified relationship between matter-and-energy and space-and-time the exact thing Einsteins General Relativity gives us we can use this information to figure out all the different combinations of all the different forms of matter-and-energy present in the Universe today. For most of the first 9 billion years of the Universe's history, matter in the combined form of normal and dark matter was the dominant component of the Universe. ball, ten years ago, represented approximately the minimum size that the Universe was at the moment of its birth. According to the theory of inflation, the Universe: which triggered and began the hot Big Bang. Before the universe Gods Spirit hoovered over the darkness (space) . As new space gets created in the expanding Universe, the dark energy density remains constant. The Universe is: Expanding, cooling, and dark. We have found the Answers to Everything and it will be the ULTIMATE THEORY OF EVERYTHING !! That soccer [+] ball, ten years ago, represented approximately the minimum size that the Universe was at the moment of its birth. isotropic, meaning that on average, it has the same properties in every direction that we look. Once we find out the how we can work on the why. Although cosmic inflation is well known for resolving some important mysteries about the structure and evolution of the universe, other very different theories can also explain these mysteries. Copyright 1998 - 2022 SciTechDaily. Lets get real with this. The diameter of the Milky Way is 100,000 light years; the observable Universe had this as its radius when it was approximately 3 years old. Over time, this space batter began to cool and congeal. Any theory that is neither provable nor negatable is just speculation. two different techniques astronomers use to measure the expansion of space at various times/distances in the past. The stars and galaxies we see today didn't always exist, and the farther back we go, the closer to [+] an apparent singularity the Universe gets, as we go to hotter, denser, and more uniform states. But to others, this is a feature that highlights the fundamental limits of not only whats known, but whats knowable. Even with impressive current technology, the furthest the Hubble Space Telescopewas able to see was an object 12.9 billion light years away. Today, when you look out in any direction as far as the laws of physics allow us to see, the limits of whats observable extend to truly astronomical distances. Then one day I thought, This is preposterous and with the internet available I searched for alternative ideas. Before we figure out what happened before the beginning, it is important to know how physicists think it will end. similar to dark energy, but much greater in magnitude. The history of the Universe, as far back as we can. Hello everyone..See the bitter fact is that Scientists are fooling us since the very start.. And there they were. This also means that if we went back to any point in the distant past, our Universe would also have a finite, quantifiable size: smaller than it is today, dependent on how much time has passed since the hot Big Bang. Wed go back to a single point of infinite density, infinite temperature, of space having an infinitesimally small size, of a time that corresponded to zero, and where the laws of physics broke down. Whenever that time happens to be, where inflation ends and the Big Bang begins, thats when we need to know the size of the Universe. Kinney: "Standard Big Bang theory doesn't have any explanation for why the universe is so smooth and so uniform, for all these basic properties of the cosmos that we see. As for Another Earth, do you have inside knowledge or experimental evidence of your theory? In the first period, the universe grew from an almost infinitely small point to nearly an octillion (that's a 1 followed by 27 zeros) times that in size in less than a trillionth of a second. Using the scaling above, that means the current observable universe had a diameter of 21.3 million light years at that age. What if we are essentially an exploding firecracker in a larger universe? Because of how illustrative they are, Im going to plot these on logarithmic scales for you to view. March 25, 2019, An artists illustration showing the patterns of signals generated by primordial standard clocks in different theories of the primordial universe. And radiation: at 0.01% of the Universe today, its practically negligible. The large, medium and small-scale fluctuations from the inflationary period of the early Universe [+] determine the hot and cold (underdense and overdense) spots in the Big Bang's leftover glow. Their goal is to give insight into a long-standing question: what was the universe like before the Big Bang? All five forms are present, but different components dominate at different times. components in the Universe at various times in the past. Thank you folks for the sensible follow up and thoughts based on the article. So i request you all to keep patience for just a few months to witness the greatest day in the history of mankind . This is a tremendous and recent improvement by about a factor of ten over a decade ago, when we would have said no smaller than a soccer ball instead. So, we wanted to find what the observable attributes are that can be directly linked to that defining property.. Theyre like clergymen trying to explain the trinity. Again, this is theobservable Universe; the true size of the Universe is surely much bigger than what we can see, but we dont know by how much. The success of this idea lies in experimentation. This is because our current technology only lets us see so far back into the early universe. The Universe couldnt have been much smaller than that, since the constraints we have from the Cosmic Microwave Background (the smallness of the fluctuations) rule that out. What Is an Atomic Clock? The analogy of a ball sliding over a high surface is when inflation persists, while the structure [+] crumbling and releasing energy represents the conversion of energy into particles, which occurs at the end of inflation. This substance was a thick, viscous liquid that filled the universe. I think too many things are being taken for granted. According toHawking, time did not exist before the Big Bang, so there wasn't a before. Today, it's approximately the size of the child in the photo, as the bounds have shifted due to improved observational constraints. Astronomers call these three classes effects evolution (if older/more distant objects are intrinsically different), environmental (if the locations of these objects differ significantly from where we think they are) and extinction (if something like dust blocks the light) effects, in addition to the effects we may not even know are at play. In the first period, the universe grew from an almost infinitely small point to nearly an octillion (that's a 1 followed by 27 zeros) times that in size in less than a trillionth of a second.. What Scientists Think The Universe Was Like Before The Big Bang. Not if your trying to tell me that right away there were 10 million galaxies. While matter (both normal and dark) and radiation become less dense as the Universe expands owing to [+] its increasing volume, dark energy, and also the field energy during inflation, is a form of energy inherent to space itself. And my post is blasphemous. At the farthest reaches of our observable limits, the most ancient light we can see was emitted a whopping 13.8 billion years ago: corresponding to the hot Big Bang itself. There were tiny irregularities in density on minuscule scales that became the seeds of the large-scale structure observed in today's Universe. Bojowald found he had to create a new mathematical model to use with the theory of Loop Quantum Gravity in order to explore the universe before the Big Bounce with more precision. By time you get to today, the observable Universe, at 13.8 billion years old, extends for 46.1 billion light years in all directions from us. Dark energy: this makes up 68% of the Universe, and is a form of energy inherent to the fabric of space itself; as the Universe expands or contracts, the dark energy density remains constant. The signals generated by the primordial standard clock can serve such a purpose. But earlier, the Universe was dominated by matter, where it grew at a particular rate, and even before that, it was dominated by radiation, where it grew at still a different rate. The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang [1] and thought to have contained all the energy and spacetime of the Universe. No matter what value people measure for some observable attribute, there are always some models of inflation that can explain it.. What if our universe is just constantly bouncing back and forth between the next Big Bang and Big Crunch? Any smaller than that, and wed see fluctuations in the Big Bangs leftover glow that simply arent there. The Universe is out there, waiting for you to discover it. It is full of titles like, Scientist puzzled by new data, what if there is no dark matter. Surprisingly, it doesnt give us a singularity, where the Universe reaches infinite densities and temperatures at an infinitesimal size. Science is a religion. For example, during inflation, the size of the universe grows exponentially, Xianyu said. Unfortunately for the field of physics, there isn't much we can do right now to discover what happened in the milliseconds immediately following the Big Bang. We have already started to search for these signals and there are some interesting candidates already, but we need more data.. The planks era, inflationary epoch and many other things were happened during the evolution of universe. Use features like bookmarks, note taking and highlighting while reading Before the Big Bang The Origin of the Universe and What Lies Beyond. complement to the WiggleZ survey. Ha ha. Some of the galaxies are really, really old and from before this big bang. kicks a soccer ball with an Iraqi child. Please check with your country's customs office to determine what . Some researchers, including Avi Loeb of the Center for Astrophysics | Harvard & Smithsonian (CfA) in Cambridge, Massachusetts, have raised concerns about inflation, suggesting that its seemingly endless adaptability makes it all but impossible to properly test. There is big blast universe has time limit ,start from big blast and end at critical merge point. However, according to Professor Cox, there was a time before the Big Bang in which the universe actually existed. And the Deep Space Atomic Clock? Our best measurements of the dark matter, normal. As we run the clock backwards, the Universe gets smaller, but there is a limit. To some, thats a bug, demanding an explanation all its own. limits of what's observable out to a distance of 46.1 billion light-years away. So how big was the Universe when it was first born? However, there is a limit to that extrapolation, as going all the way back to a singularity creates puzzles we cannot answer. I laugh at you. But if were talking about theobservable Universe, and we know were only able to access somewhere between the last 10-30 and 10-35 seconds of inflation before the Big Bang happens, then we know the observable Universe is between17 centimeters(for the 10-35 second version) and168 meters (for the 10-30 second version) in size at the start of the hot, dense state we call the Big Bang. Lets look to the Universe we see to find out. But can we go back arbitrarily far? In an effort to find some characteristic that can separate inflation from other theories, the team began by identifying the defining property of the various theories the evolution of the size of the primordial universe. The Big Bang marked the origin of the universe, the beginning of its expansion from a singularity (or something close to a singularity), a single point that was infinitely small, infinitely hot, and infinitely dense. After the big bang the universe undergoes through many processes and still it is expanding. But i cant reveal my theory for atleast next 8 months because its being peer reviewed and moreover its being submitted for detailed analysis and experimental verification by esteemed scientists / physicists . Today, it's approximately the size of the child in the photo, as the bounds have shifted due to improved observational constraints. Paul M. Sutter is a research professor in astrophysics at SUNY Stony Brook University and the Flatiron Institute in New York City. This will cause all matter to smash together in an event that is essentially the opposite of the Big Bang. For the Universe, and in particular for how the fabric of the Universe evolves with time, those rules are set forth by our theory of gravity: Einsteins General Relativity. I have worked on this problem for the last 37 years along with my team of esteemed physicists and finally after years of sleepless nights i have found all the deep hidden answers and discovered the FINAL COSMOLOGICAL THEORY which describes every bit about universe and all the answers about universe,its origin,myth of big bang,illusion of time,what was there before our universe came into existence,myth of supernova and black holes,cosmic microwave backround,parallel universe,multiverse,branes and the ever idiotic standard model !!!!! Without any clock information, we dont know if the film should be played forward or backward, fast or slow, just like we are not sure if the primordial universe was inflating or contracting, and how fast it did so. Standard clocks in different theories of the primordial universe predict different patterns of signals because the evolutionary histories of the universe are different. From the reviews: What happens to the big bang singularity within string theory? Generally speaking, most physicists don't look much into what happened before the Big Bang. Sergio, please do some real research and stop being a troll. The universe is currently 13.7 billion years old, but the time when radiation and matter contributed equally to the density of the universe was about 50,000 years after the big bang. According to Carroll, this theory works similarly to how radioactive particles decay. All Rights Reserved. Here in our Universe, based on what's in it today and how fast the Universe is presently expanding, [+] we can determine how much of the Universe was dominated by any different form of energy we care to look at: normal matter, dark matter, dark energy, neutrinos, and radiation. This is scitechdaily,not kjv only bible study group. Ha ha. extrapolate our Universe back to a singularity. The Big Bang: Before the Dawn: Directed by Ashley Gething. Picture Information. Even though we know that the Universe is 46.1 billion light years in any direction today, we need to know theexact combination of what we have at each epoch in the past to calculate how big it was at any given time. In truth, it might even beinfinitein extent, as whatever the Universe did in the early stages of inflation is unknowable to us, with everything but the last tiny fraction-of-a-second of inflations history being wiped clean from what we can observe by the nature of inflation itself. No one can possibly have as poor grammar and lack of sense as you have displayed. Always a pleasure to listen to intelligent and learned people. There was nothing material before the big bang. The fact that it drops in energy density faster than matter means it gets relatively less and less important as time goes on. The creative mind plays with the objects it loves. -Carl Jung. Before the Big Bang The Origin of the Universe and What Lies Beyond - Kindle edition by Mersini-Houghton, Laura . Created in association with the American Museum of Natural History. What we'll find is that, today, the Universe is transitioning to a phase where it expands exponentially, and where distances between objects will grow without bound. converting almost all of that energy into matter and radiation. see using a variety of tools and telescopes, out to the maximum present depth of SDSS. By its very nature, inflation wipes our Universe clean of any information that came before it, imprinting only the signals from inflations final fractions-of-a-second onto our observable Universe today. They made it up to balance the equations to promote their theories. Then, in a trillionth of a trillionth of a trillionth of a second, it exploded outward, doubling and re-doubling and re-doubling in size at a rate faster than the speed of light in a phenomenon physicists call inflation. One theory for how our universe will end is known as the Big Crunch. This can be a hard topic for people to grasp, as we normally think of the progression of time as an important part of how events play out. However, there is a limit to that extrapolation, as going all the way back to a singularity creates puzzles we cannot answer. This image shows a slice of the matter distribution in the Universe as simulated by the GiggleZ [+] complement to the WiggleZ survey. Either its expanding or its contracting. ESO/INAF-VST/OmegaCAM. And notably here, all these other cosmologies has exactly the same problem. But if were right about the intrinsic brightness (or size) of an object we see, then based on a simple brightness/distance relation, we can determine how far away those objects are. After 50 years of missions, were finally ready to know: is there life on Mars? NASA, ESA, R. Windhorst, S. Cohen, and M. Mechtley (ASU), R. OConnell (UVa), P. McCarthy (Carnegie Obs), N. Hathi (UC Riverside), R. Ryan (UC Davis), & H. Yan (tOSU), The Hercules galaxy cluster showcases a great. @Sergio, AE: No. This is the primary source of information physicists rely on to learn about what happened before the Big Bang. This view is only accessible to us today, 13.8 billion years after the start of the hot Big Bang. What Was Before The Universe? Credit: CfA/Zhong-Zhi Xianyu, Xingang Chen, Avi Loeb. As we run the clock backwards, the Universe gets smaller, but there is a limit. While the Big Crunch isn't the only theory for how the universe will end, it just might be the key to figuring out what might have taken place before the Big Bang. Also,Sergio, no just no. > Subscribe Free to Email Digest, Scientists Shine a Light on What Comes Up When You Flush Thanks to new research, scientists see the impact of flushing the toilet in a. Why? This logarithmic view of the Universe shows our solar system, the galaxy, the cosmic web, and the [+] limits of what's observable out to a distance of 46.1 billion light-years away. No evidence from you, no new believers for you. was once dominated by a large amount of energy. 25.03.2022. Some size and time milestones are marked, as appropriate. Just by knowing, today, what makes up your Universe and what the expansion rate is right now, you can determine: We can do this as long as the types of energy in the Universe remain constant: as long as you dont convert one form of energy (like matter) into another form of energy (like radiation) that obeys a different set of rules as the Universe expands. It was a push of energy from a non physical dimension into absolute space to create a physical dimension. I bring these up because these different components, radiation, matter and dark energy, all affect the expansion of the Universe differently. Where there is no universe, no time, no causes or effects, not even . The genius is not coming up with a theory, but in proving or disproving it. By Peter Reuell, Harvard-Smithsonian Center For Astrophysics So outside of our universe, time has no meaning. "Before the Big Bang" would be, by definition, outside of our universe. For physicists like the late Steven Hawking, studying the moments immediately after the Big Bang are much more important for understanding physics. At that point, things were cooled enough that quarks and electrons, the building blocks of all matter, came to be. The idea that we are living in a multiverse has been played around with by others before, but Carroll and Chen's research has helped to lay the foundation of how the multiverse could actually exist. Cosmic Microwave background has a known shape, but its amplitude is dependent on the specific model of inflation. the standard model assumes that the generations are all the time reversible, however that might not be the case in the very first stage of an early universe.That needs to be proven, too! Such particles should exist in any theory and their positions should oscillate at some regular frequency, much like the ticking of a clocks pendulum. The Future of Black Hole Images is Bright. Cutting-edge space missions take us back 13.8 billion years to the very beginning - the origin of the Universe. light years away in the distant Universe. Before we figure out what happened before the beginning, it is important to know how physicists think it will end. [1] $29.99. What if the red shift was misinterpreted. None of that is true, people are not animals, nothing evolved, there was no big bang, God created the heavens and the earth, and God created man. Today, after traveling through our expanding Universe, that light finally arrives here on Earth, carrying information about objects that are presently located some 46.1 billion light-years away. The attributes people have proposed so far to measure usually have trouble distinguishing between the different theories because they are not directly related to the evolution of the size of the primordial universe, he continued. The Big Bang theory says that our universe began as a point of infinite gravity and density called a singularity. From where I sit you look like one of those prick who acts stupid in order to give people who have an opinion you dont agree with a bad name. If we can answer that question, we can learn how far back we can extrapolate the Universe we have today, and can learn what its minimum size as close as we can get to the birth of what we know as our Universe must have been. I was drawn in for decades after my science degree. There must have been a cutoff to how far back we can extrapolate that our Universe was filled with matter-and-radiation, and instead there must have been a phase of the Universe that preceded and set up the hot Big Bang. In our Universe, if we want to know anything about either what it will do in the future or what it was doing in the past, we need to understand the rules and laws that govern it. Did time start with this big bang too? While it is certainly possible that something existed before the Big Bang, it most likely wasn't as interesting as we might think. Hospital Corpsmen 3rd Class Tarren C. Windham kicks a soccer ball with an Iraqi child. While the James Webb Space Telescope has been sending back exciting images NASA's Goddard Space Flight Center has numerous examples posted online it may take several years before we can expect to see it make any major discoveries regarding the Big Bang. But for the first few. The study will appear in Physical Review Letters as an Editors Suggestion. These and other pre-eminent questions, whose implications go far beyond the boundaries of physics and even of science, lie at the forefront of today's research in theoretical particle physics and cosmology. Neutrinos: at just 0.1% of the Universe, neutrinos are interesting because theyre very light. Now, a team of scientists led by the CfAs Xingang Chen, along with Loeb, and Zhong-Zhi Xianyu of the Physics Department of Harvard University, have applied an idea they call a primordial standard clock to the non-inflationary theories, and laid out a method that may be used to falsify inflation experimentally. That places a cutoff on how far you can extrapolate the hot Big Bang backwards: to a time of ~10-35 seconds and a distance scale of ~1.5 meters. we can determine how much of the Universe was dominated by any different form of energy we care to look at: normal matter, dark matter, dark energy, neutrinos, and radiation. These came into existence around one ten-thousandth of a second after the. Heres why that limit exists, and how we can figure out the minimum size of the early Universe. The large-scale structure of the Universe grew from a more uniform, hotter, denser state, and only occurred as the Universe gravitated, expanded and cooled. If it's possible for the Big Crunch to take place in the future, whose to say one hasn't already occurred and we are currently existing in the second, third, fourth, or even millionth generation of our universe? We can even plot this out: given how much time occurred since the hot Big Bang, how large was the size of the observable Universe? Hover to zoom. These fluctuations, which get stretched across the Universe in inflation, should be of a slightly different magnitude on small scales versus large ones. Ha ha ha ha. One of them is that the temperature fluctuations in the Big Bangs leftover glow what we see today as the Cosmic Microwave Background radiation would have been as large as the ratio of the maximum energy achieved to the Planck scale, the latter of which is around ~1019 GeV in terms of energy. He regularly appears on TV and podcasts, including "Ask a. The relative importance of different energy. There was no big bang the universe is electric its not expanding theres no black holes there plasmids theres no dark energy dark matter all bulshit made up to keep the false hope of gravitic and nebula forming galactic bulshit going no gas suns its call plasma and Electricity. How can the universe be at least 46 billion light years across but only 14 billion years old? The Universe certainly got much hotter than it ever gets at the Large Hadron Collider, which only reaches ~104 GeV, but those upper size-limit constraints have a lot of flexibility.). That range has been improved with the capabilities of the James Webb space telescope, which (per Time) can see 13.6 billion light years. Instead, theres a limit: a smallest possible size that the Universe could have had. This transformation from inflationary energy into matter and radiation represents an abrupt change in the expansion and properties of the Universe. This theory, based on Einstein's Theory of General Relativity, states that our universe's current expansion will eventually slow to a halt. If the Universe were always filled with matter or radiation, that would be exactly what were able to do. Then, when was big bang? document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); SciTechDaily: Home of the best science and technology news since 1998. One can continue to extrapolate this forwards and backwards in time, but only so long as the components of energy that exist today didn't have transitional points.
