what was before the singularity

(Nov. 12, 2018) http://www.physorg.com/news73844848.html, Redd, Nola Taylor. Visit our corporate site. Perhaps a sea of universes, each with a different set of laws dictating its physical reality. Further, he predicted that as computers advanced . Chris - What's being referred to here is what happened about thirteen point eight billion years ago. My question to do with nerves. In that case . One of the most common ones is "a singularity," which refers to an instant where all the matter and energy in the Universe was concentrated into a single point. They haven't completely removed the infection so it then comes back with a flourish. ET on the National Geographic Channel. April 16, 2010. The initial singularity was a singularity of seemingly infinite density thought to have contained all of the mass and space-time of the Universe before quantum fluctuations caused it to rapidly . But some scientists think the universe started, not with a Big Bang, but with a Big Bounce. Information presented on this website is the opinion of the individual contributors and does not reflect the general views of the administrators, editors, moderators, sponsors, Cambridge University or the public at large. So what they're saying is if we can find out what it is about these molecules, these antibiotic molecules, that make the cells do this then what we could do is to focus on that aspect of their behavior and come up with a newclass of drugs which will enable us to make anti virus drugs which will be potentially very useful in the treatment of a whole raft of different virus infections because they tried this against herpes virus that causes cold sores and genital disease. Share Surprise: the Big Bang isnt the beginning of the universe anymore on Facebook, Share Surprise: the Big Bang isnt the beginning of the universe anymore on Twitter, Share Surprise: the Big Bang isnt the beginning of the universe anymore on LinkedIn, Countless scientific tests of Einsteins general theory of relativity have been performed, subjecting the idea to some of the most stringent constraints ever obtained by humanity. New predictions like these are essential for demonstrating the validity of a proposed fine-tuning mechanism. The Big Bang still happened a very long time ago, but it wasnt the beginning we once supposed it to be. Mathematically, its tempting to go as far as possible: all the way back to infinitesimal sizes and infinite densities and temperatures, or what we know as a singularity. In every direction we care to observe, we find stars, galaxies, clouds of gas and dust, tenuous plasmas, and radiation spanning the gamut of wavelengths: from radio to infrared to visible light to gamma rays. (Nov. 12, 2018)) https://www.space.com/6303-glimpse-big-bang.html, NASA Universe 101. April 18, 2001. Inside this extremely small, massively dense speck of heat and energy, the laws of physics and time as we know them cease to function. So they wouldnt necessarily be located on a planet in the so-called habitable zone. But I will give you a hypothetical answer for this question. And yet, instead, what were observing is that the universes initial expansion rate and the total amount of matter and energy within it balance as perfectly as we can measure. (Nov. 12, 2018) http://www.sciencedaily.com/releases/2007/02/070221093222.htm, Than, Ker. That is the threshold at which point an AI reaches human-like sentience a . Could you please explain that scientifically. Stephen Hawking might know the answer. Travel the Universe with astrophysicist Ethan Siegel. In relativity, we use the term "event" to mean a certain position in space at a certain time. Chris - Yeah. The B650M Project Zero also comes equipped with plenty of extensibility and support for modern standards and boasts dual PCIe 4.0 x4 M.2 slots, M.2 Shield Frozr to keep your high-speed storage cool, DDR5, 2.5G LAN, and support for Wi-Fi 6E. The strategy game StarCraft II may be the next to have a machine as reigning champion. Where the matter came from, that is "inside" that singularity is unresolved. In Brief. (Credit: E. Siegel). In models based on GR, time and space only exist for . The universe, as we see it today, is more evolved than it was in the past. Under this rationale, however, it is only possible to find a human creator in the software that constitutes the initial input to the creation of an AI, but not in any of the machine-generated outputs, which would not qualify as "works" under copyright law. Bongani-Yes. If we put this into a computer we can model how it must be growing and evolving, and if you can model how it's growing and evolving getting bigger you can then win the clock back to ask what would it look like in the early days? No one was there to see the beginning of the universe but we can infer what happened because there are still what people dub the echoes of the Big Bang knocking around in the universe today. All of a sudden the oven door just exploded and I couldn't understand why. Lebo - Morning. What that's saying is at the moment what we do when a person has a bacterial infection is we say right you have say a urine infection we'll give you X number of days of this drug, take this and then you'll be better. Eusebius - Cheers, thanks a lot. Chris - Good morning. Actually, that's based on the fact that when people take a drug, we know that if we give it for that long we're going to cure everybody. Top among the leading experts confident that the singularity is a near-future inevitability is Ray Kurzweil, Google's director of engineering. How? Until the day comes where we discover how to extract more information from the universe than presently seems possible, we have no choice but to face our ignorance. May 22, 2001. This is going to lead to possibly resonances in the glass or a focus of force in one place which could encourage the glass to suddenly give. Yes, "the laws of physics break down" at singularities. Get counterintuitive, surprising, and impactful stories delivered to your inbox every Thursday. April 27 2010. 2000. So my question is this. All aboard! I just want to ask, once you open up a good bottle of wine, all of a sudden you just have wine flies coming from where? It just seemed that way from mankind's point of perspective. [The Big Bang to Civilization: 10 Amazing Origin Events]. [4], Although there is no direct evidence for a singularity of infinite density, the cosmic microwave background is evidence that the universe expanded from a very hot, dense state. Just consider the effect of mass on time. (Nov. 12, 2018) http://www.universetoday.com/2008/06/13/thinking-about-time-before-the-big-bang/, Britt, Robert Roy. He enjoys writing most about space, geoscience and the mysteries of the universe. My colleagues and I are hopeful that the coming months will result in oneor perhaps manymulti-messenger observations that will push the boundaries of modern astrophysics. June 6, 2008. Although its tempting to simply extrapolate forward in time, when things will be even larger, less dense, and cooler, the laws of physics allow us to extrapolate backward just as easily. First energy was created after that matter w. Oct. 21, 2011. If you want to know the answer to the biggest question of all the question of our cosmic origins you have to pose the question to the universe itself, and listen to what it tells you. [source: Redd]. Keep reading to learn about some of them. As such, a singularity is by definition no longer part of the regular spacetime and cannot be determined by "where" or "when". It's just an ordinary old cake. What is the 'ship of Theseus' thought experiment? According to the most popular version of the singularity hypothesis, I.J. (Nov. 12, 2018) https://www.space.com/17661-theory-general-relativity.html, Soter, Steven and Tyson, Neil deGrasse, (editors). " For the Big Bounce idea to work, it has to find a way around the singularity theorems developed by British physicists Roger Penrose and Stephen Hawking, which suggest that a contracting universe would shrink all the way down to a singularity, in the fashion that a massive dying star eventually condenses to form a black hole. 2 Answers. Think of it as a cosmic exhaust valve. By: Robert Lamb & Patrick J. Kiger | Updated: Apr 15, 2021 What came before the beginning? Because these flies would normally track down fruit, rotting fruit, and fermenting fruit that's dropped on the floor. is that it has no. Inflation offers successful explanations for the puzzles that we simply have to say initial conditions for in the hot Big Bang. (Nov. 12, 2018) https://www.space.com/8293-universe-born-black-hole-theory.html, Davies, Paul. What was there before there was anything? What happened before the Big Bang? And we think the universe came from a singularity, that's the dot that's being referred to by Bongiorni here, and we think this singularity is extremely small but extremely energetic and for some reason, that we dont understand, this energy unleashes, the universe pops into existence and very rapidly begins to inflate like a balloon blowing up, and it inflates very very fast and its very very hot. Your Privacy Rights The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and . Very much appreciated. April 9, 2010. Before the existence of singularity, there was nothing. Lastly, and perhaps most importantly, we can no longer speak with any sort of knowledge or confidence as to how or even whether the universe itself began. Get the latest stories in your inbox every weekday. He has published eight books and nearly 200 scientific papers related to astrobiology and planetary habitability. As scientists know now, the universe is constantly expanding. But extrapolating beyond the limits of your measurable evidence is a dangerous, albeit tempting, game to play. They're over prescribed by doctors and so forth. But after the swelling came down, the nerves did not return to their original shape, hence I've lost my sight. [3], Another procreation based on M-theory and observations of the cosmic microwave background (CMB), states that the Universe is but one of many in a multiverse, and has budded off from another universe as a result of quantum fluctuations, as opposed to our Universe being all that exists. Now what came before the universe we don't know. In chaotic inflation theory, this concept goes even deeper: an endless progression of inflationary bubbles, each becoming a universe, and each of these birthing even more inflationary bubbles in an immeasurable multiverse [source: Jones]. How do "all in one" dishwasher sachets work? We are just beginning to understand quantum entanglement, and it is not yet clear whether it can be used to transfer information. Brian says why can I hear my phone's alarm but not my wife's alarm, and yet she wakes up earlier than I do? "Description & Origins of Inflation Theory. " Singularity was born after energy and matter were created. Do nerves regenerate? I can't get my mind. But what is this one about? The reason that people have this sort of mantra about always complete your course of antibiotics. Make a donation to support the Naked Scientists. However, there's a significant difference of opinion . "What Existed Before the Big Bang?" Fol - Two or three weeks ago, as I recall, you said that air was - or air is - a fluid. Is it possible for me to be HIV negative, to have sexual intercourse with someone is HIV positive and then test negatively after but, nevertheless, remain infectious? 2000. While futurist Ray Kurzweil predicted 15 years ago that the singularitythe time when the abilities of a computer overtake the abilities of the human brainwill occur in about 2045, Gale and his. The first is "personality-related". One model, using loop quantum gravity, aims to explain the beginnings of the Universe through a series of Big Bounces, in which quantum fluctuations cause the Universe to expand. (Nov. 12, 2018) http://www.armaghplanet.com/blog/the-big-bounce-theory-what-is-it.html, Science Daily. Dec. 3, 2012. It turns out, famed physicist Stephen Hawking has an answer, which he gave in an interview with his almost-as-famous fellow scientist, Neil deGrasse Tyson. But something really weird must have happened for black holes to not possess them. Caroline, good morning. In the early 20th century, Albert Einstein came to very similar conclusions with his theory of general relativity. Chris - Well this is an interesting study because for a long time we've been counseling patients that antibiotics are for treating bacterial infections and that because the majority of colds and runny noses are caused by viruses then taking antibiotics will do no good whatsoever. Good's intelligence explosion model, an upgradable intelligent agent will eventually enter a . [5], Various new models of what preceded and caused the Big Bang have been proposed as a result of the problems created by quantum mechanics. Killer bees stung a man 250 times in swarm attack, but he survived. It's based on some sound science in the sense that if we take TB as an example, one of the reasons why tuberculosis is such a massive problem, and in fact there's probably about 2 billion people around the world who are infected with TB. No one was there to see it. They tried again Zika virus tried it against flu and it had the same effect against all these viruses. Stay up to date on the latest science news by signing up for our Essentials newsletter. Eusebius - Indeed. [A] theoretical condition that could arrive in the near future when a synthesis of several powerful new technologies will radically change the realities in which we find ourselves in an unpredictable manner The main concern associated with the singularity is its potential to change the world entirely. Did Our Universe Bubble Out of a Previous One? Chris - No. Ask Ethan: Do we know why the Big Bang really happened? Chris - Now the way we test for HIV is a person who has had an exposure in the past, or just wants to know their status will supply a blood sample. Because if the immune system is capable of doing this, which it clearly is, it might be possible to try and find a way to persuade everyone elses immune system to do the same thing and clear the virus in their body as well. Some contemporary scientists have arrived at an idea with striking parallels. There's something called the cosmic microwave background radiation and this is effectively radiation left over from when those initial phases of the big bang happened. Long ago, the universe was smaller, denser, and hotter. No matter where or how we look at the universe, its full of matter and energy absolutely everywhere and at all times. Then, in the 1920s, Edwin Hubble began measuring individual stars in these nebulae and eventually determined the distances to them. In general relativity, a naked singularity is a gravitational singularity without an event horizon. "The Big Bang: What Really Happened at Our Universe's Birth? " Do nerves regenerate? Nearly 50 years later, it isnt just for black holes. Feb. 22, 2007. Hubbles great discovery concealed a tension that still haunts cosmology, Hawking radiation isnt just for black holes, study shows, Natural experiments win the 2021 Nobel Prize in economics. The antennae on the flies are decorated with nerve endings which have these chemical receptors on them for the very same volatile agents which are given off by wine. When it comes to AI, singularity is kind of like the Terminator. Case closed? Why would they use primitive radio waves to send messages? Almost Became a Nation of Hippo Ranchers, Lost for 50 Years, Mysterious Australian Shipwreck Has Finally Been Found, The Real History Behind 'Queen Charlotte: A Bridgerton Story', Burrowing Bunnies in Wales Unearth Trove of Prehistoric Artifacts. Still other models revolve around the formation of the pre-Big Bang singularity itself. The universe is only 13.8 billion years old, but we can see back 46.1 billion light-years. Live Science is part of Future US Inc, an international media group and leading digital publisher. I suspect that you're right. Brandon is the space/physics editor at Live Science. But in fact there are some people in the population who dont need it for anything like that long and we just haven't looked. It's a gas, but it's also fluid and it behaves as a fluid. One is that it appeared to describe our universe on the largest scales, where things appear similar, on average, everywhere and in all directions. Singularity, explained. Lebo good morning. The technological singularity, to use its full title, is a hypothesis predicted on the creation of artificial superintelligence. [6], "The Big Bang: What Really Happened at Our Universe's Birth? And everything like how do we know it even existed in all of that stuff? If his own phone is closer to to him, obviously it's going to be louder because the further away you are from a sound source the quieter the sound is, so that might be part of it. Georges Lematre published a paper in 1927 that proposed the universe started out as a singularity and that the Big Bang led to its expansion [source: Soter and Tyson]. What was the longest-lasting civilization? Profile: Georges Lematre, Father of the Big Bang. " Thats precisely what cosmic inflation gives us, plus more. Eusebius - The just don't make carrots like they used to. The full suite of data, including the observations of the light elements and the cosmic microwave background, leaves only the Big Bang as a valid explanation for all we see. This neutrino background comes to us, remarkably, from just ~1 second into the hot Big Bang. (Nov, 12, 2018) http://www.physorg.com/news79009171.html, Moskowitz, Clara. The idea that the universe began from a singularity, and thats what the Big Bang was, needed to be jettisoned the moment we recognized that an inflationary phase preceded the hot, dense, and matter-and-radiation-filled one we inhabit today. Once you cross the threshold to form a black hole . livescience.com-interesting-person-plain-button, The Big Bang to Civilization: 10 Amazing Origin Events. If you take say a spoon and dribble water over the back of it you'll see it sticking to the surface of the spoon and then coming off at an angle. Chris - Okay. Eusebius - Thank you sir. Could that have caused the oven door to explode? When you have a gas it behaves in exactly the same way, the molecules are just a bit further apart. Terms of Use Aug. 13, 2009. Astronomers first observed the CMB in 1965, and it quickly created problems for the Big Bang theory -- problems that were subsequently addressed (for a while) in 1981 with the inflation theory. Eusebius - Chris, this story fascinates me, our science story of the week. Future US, Inc. Full 7th Floor, 130 West 42nd Street, Some scientists propose that our universe may have been born inside a black hole, and every black hole in our own universe could each contain separate universes as well [source: Choi]. Very quickly, a handful of exact solutions were found thereafter. Yes, you're right. Subscribers will get the newsletter every Saturday. Can we see farther back in space than we can in time? And two, if you solved the governing equations for this solution the Friedmann equations youd find that the universe it describes cannot be static, but must either expand or contract. Computer scientists warn of what they term an AI Singularity. And physicists are running very complicated simulations saying well we know where the galaxies are, give or take today, or many of them. And that's what they're doing to try to get a model of where we came from and where we might ultimately end up. Let's take one from Twitter. They come laced with dynamite or something! This idea, of a singular beginning to space, time, and the universe, was long known as the Big Bang. But certainly these questions are being asked and people are looking to minimise the exposure that people have to antibiotics because there are always side effects. This isn't the first time Hawking has discussed this theory. While futurist Ray Kurzweil predicted 15 years ago that the singularitythe time when the abilities of a computer overtake the abilities of the human brainwill occur in about 2045, Gale and his co-authors believe this event may be much more imminent, especially with the advent of quantum computing. Eusebius -Thank you Caroline. When we stack up the scorecard, we find the following: But things get really interesting if we look back at our idea of the beginning. Whereas a universe with matter and/or radiation what we get with the hot Big Bang can always be extrapolated back to a singularity, an inflationary universe cannot. This procreation also predicts a cyclic model of universes, with a new universe being created after an old one is destroyed, each with different physical constants. Privacy Statement What's your question for us? Thank you so much Chris love your work. But my money would be on it being the fact that as the oven gets hot then you're going to get expansion, shape changes, and uneven loading by forces of the glass and that's going to focus force in one place and cause it to crack, especially if the glass over time has developed a weakness.
