Infinite-dimensional spaces are widely used in geometry and topology, particularly as classifying spaces, such as Eilenberg−MacLane spaces. Possibly an infinite number of duplicate observable universes. So, what's out there? What Is The Fibonacci Sequence? 3. the speed of light is finite. This document is subject to copyright. However, due to the inflation of the universe, as well as the apparently accelerating expansion of every observable corner of the universe, the most distant light we have been able to detect is from roughly 46 billion light-years in every direction. This interview was conducted in 2001 at ESA's European Space Technology Centre (ESTEC) in Noordwijk, the Netherlands, during an international workshop to discuss the scientific programme of the Planck satellite. There seems to be only what the French mathematician and physicist Blaise Pascal called “the eternal silence of these infinite spaces.” Extraterrestrial life, if it exists, is either very well hidden or just too far away in time and space. Space couldn’t be that infinite and yet remain that empty. When you are a kid infinite is a hard number to wrap your head around. One hydrogen pile looks the same as the next to me. All of space was involved in the Big Bang, which had previously been compressed at nearly infinite density. And if the Universe is finite, well, it's finite. Why Is It So Special? If there is a finite probability of something happening (ie. Many people think of the Big Bang occurring in a completely empty void, a vacuum without energy or matter, when suddenly a massive expansion began, spewing matter and energy out at inconceivable speeds, which eventually went on to form all the galaxy clusters, nebulas, stars, planets and moons we know today. 1 Recommendation. We don't know. Short. The difficulty we have trying to imagine infinite space, and infinite time, are at the source of the Big Bang theory. Extrapolating this out further, there would also be a place where those same arrangements of atoms and molecules formed another Earth, with life that evolved in the same way, meaning that there would also be somewhere else in this infinite universe where another “you” existed. 1 Recommendation. Aristotle ’s answer was that the material universe must be spatially finite, for if stars extended to infinity, they could not perform a complete rotation around Earth in 24 hours. Subscribe to our mailing list and get interesting stuff and updates to your email inbox. Mathematically, this usually means no restrictions on the domain or co-domain of the two-dimensional space. Also would there be any possibility of interaction between these universes? the facts are: 1. the BBT states that the Universe had a beginning (roughly speaking) in our past. In astronomy and cosmology, space is the vast 3-dimensional region that begins where the earth's atmosphere ends. That's an "at least" figure. If there is a finite probability of something happening (ie. Two possiblities exist: either the Universe is finite and has a size, or it's infinite and goes on forever. If so since ∞ * ∞ = ∞ is also true, can there be an infinite number of universes, all in the same space? The Shape of Space. If so since ∞ * ∞ = ∞ is also true, can there be an infinite number of universes, all in the same space? Is the universe infinite? Short. BrianFraser says: March 26, 2015 at 5:23 PM . If it is spatially infinite, what are the consequences of this? The "Macro-cosmos" is boundless, borderless and eternal a combination of space and energy in its multiple forms. One of the more popular theories for this universal shape is a “closed loop”. The initial answer to whether the universe is infinite or finite is a resounding… we don’t know. If it is infinite you can imagine looking out into space in any direction and there being a star. We are incapable of really imagining that space is infinite … Is Space Infinite? Is space filled with infinite energy?. Common examples are the infinite-dimensional complex projective space K(Z,2) and the infinite-dimensional real projective space K(Z/2Z,1). It can be infinite because everything has an eventual endpoint and space isn't a thing--it's literally the opposite of a thing. Here's how smart they are. On a larger scale, when we look across the universe, it appears flat, almost like a sheet of paper, and there is no observable curvature. Actually, it's probably still not enough pencils. 3. For example, are there an infinite number of stars and planets, with an infinite number of civilizations – including an infinite number of civilizations like ours? Is space infinite? If space is infinite then stars and planets and LIFE is infinite right? Here he clarifies the concept of 'flatness', and explains why we may never get to know whether the Universe is finite or infinite. If so, since ∞ + ∞ = ∞ is it possible for two universes to exist in the same space but with an infinite distance between them? But, as these kinds of things usually go, the answer is both simple AND complicated. Explore this age-old question. Have people estimated…: Is Space Infinite? Credit: SOHO - ESA & NASA When we leave the solar system, we find our star and its planets are just one small part of the Milky Way galaxy. How Big Is It and Does It Bite? Is the universe infinite? Mathematically, this usually means no restrictions on the domain or co-domain of the two-dimensional space. Or is Space finite. I'm not IT, I just happen to be one of the few in our office who knows his way around the computer, so I often get asked for help. For example, what is the size and shape of space? I was asked to answer this a while ago, and have sat on it trying to think of a good way to put this. A space can be two-dimensional and infinite if it does not have defined bounds. It could be much larger than that, but we have no way of knowing. Infinite definition: If you describe something as infinite , you are emphasizing that it is extremely great in... | Meaning, pronunciation, translations and examples However, we continue to observe the “opposite” sides of the universe, hoping that we can recognize patterns of similarity, like what is seen on our planet, where a person would eventually reach their initial location if they walked in one direction long enough. Infinite space is boundless, borderless and eternal. In our hu-man words, this means 13.8 billion light-years in all directions, the Universe doesn't repeat. Comprehending these numbers is nearly impossible for our relativistic brains, so most people think of the universe as an infinitely large and endless void. Given this theorized limitation, the universe would still be considered finite. Neither your address nor the recipient's address will be used for any other purpose. Or better put, does space simply go on forever? More space. I'm no physicist, or highly educated. Couldn't there be exact copies of yourself living in them? I mean if you have a one in a quadrillion chance of intelligent life evolving on a planet you would still have an infinite number of quadrillions and an infinite number of the one that has life. The light from beyond that universal “edge” hasn’t had enough time since the Big Bang to reach Earth or our observational satellites in space. Keywords: nature of space and time, space is below value of energy, space is not form of energy. How Are Satellites Put Into Orbit and Kept Up There For So Long? part may be reproduced without the written permission. What is Quantum Entanglement: Explained in Simple Words, Science and Ultimate Reality: Quantum Theory, Cosmology, and Complexity edited by John D. Barrow. Science Technology Today. That’s why we can detect light from 46 billion light-years away (also thanks to gravitational lensing), even though our universe has only existed in its present form for 13.8 billion years. So it could be something like a finite region of space with matter within an infinite region of space with emptiness surrounding the matter. It is possible that it does not have an end, but that is all relative to time. If space were negatively curved, like the surface of a 4D saddle, distant light rays would diverge. Photo taken by the Hubble Space Telescope External So, is the Universe Infinite? So, in the spirit of he who smelled it, dealt it. It could be 100 billion light-years, or it could be a trillion light-years. Our existence and power exceeds limitation in any way. None of this has anything to … If space were negatively curved, like the surface of a 4D saddle, distant light rays would diverge. Alright, in a box of space about yay big (show with hands), there's a finite number of particles that can possibly exist in that region, and those particles can have a finite number of configurations considering their spin, charge, position, velocity and so on. Full text Space is Endless, Unlimited, Infinite If the Universe is truly infinite, if you travel outwards from Earth, eventually you will reach a place where there's a duplicate cubic meter of space. This site uses cookies to assist with navigation, analyse your use of our services, and provide content from third parties. There are only 1080 particles in the observable Universe, so that's much less than the possible configurations of matter in a cubic meter. Also would there be any possibility of interaction between these universes? None of this has anything to … Does the cosmos go on forever, or is outer space finite? You can be assured our editors closely monitor every feedback sent and will take appropriate actions. Your opinions are important to us. What we know with certainty is that the Big Bang occurred 13.8 billion years ago, meaning that is the age of the universe. I'm back to shed my cone of shame and talk big universe. ), abbreviated as IS, are powered exoskeletons, which were originally meant for outer space exploration. Your email address is used only to let the recipient know who sent the email. Space is infinite as it is expanding all the time. [citation needed] Fractals Expansion of universe after the big bang illustration (Photo Credit : Andrea Danti / Shutterstock). And my brain has already begun to melt in anticipation of discussing the implications of an infinite Universe. Have people estimated different sizes? There remains no clear or definitive evidence that the universe is either finite or infinite, although there are some intriguing arguments and proposed theories on both sides. Usually it's just 'My MSWord doesn't work' or something, but this one really stuck with me. I mumbled, did some hand waving, glossed over the mind-bending implications of both possibilities and moved on to whatever snarky sci-cult reference was next because I'm a bad host. 1 decade ago. You were told wrong. Some theoreticians and astrophysicists, including Einstein, attempted to determine a “shape” for the universe, particularly after Einstein theorized that time and space can be bent or even folded. It's estimated that the universe is 156 billion light … What we are saying is that space is infinite. Stars would litter everything. The longer you peer, the more stars seem to pop into existence, more than you could count if you took all night! or, by Fraser Cain, Universe Today. Assuming of course, that other lifeforms haven't discovered infinite pencil technology, or there's a pocket dimension containing only pencils. So there would be an infinite number of galaxies and planets in an infinite universe. So the interesting part of the universe is finite - but space itself is infinite. 2. When is the last time you looked up into a star-strewn sky miles and miles from any other source of light. This set is dense in many sequence spaces. And at least one of them is going to have a beard. Apart from any fair dealing for the purpose of private study or research, no The space of infinite possibilities is bigger than just a prompt for monthly goals. In the first instants of the universe following the Big Bang, the volume and density of matter was somewhat uniform, but as soon as cooling and differentiation into atoms began, areas of mass accumulation and areas of empty space became more defined. Beyond our Milky Way galaxy lies more than 150 billion other galaxies, each with their own massive amount of stars. All of the energy and matter began expanding as it moved apart at the speed of light away from everything else; similarly, the empty space between objects was also expanding (often faster than the speed of light). It’s a statement of personal inspiration. and 240 more episodes by Daniel And Jorge Explain The Universe, free! You'll eventually find entire duplicate observable universes with more yous also collecting other yous. (Theories about size of space. After moments like this, I prefer to douse it in some XKCD, Oatmeal and maybe some Candy Crush. Possibly, we can't know. Long time lurker, first time poster, yadda yadda. If so since ∞ * ∞ = ∞ is also true, can there be an infinite number of universes, all in the same space? However, anyone with a vague knowledge of our galaxy and universe knows that there are actually billions of stars in the Milky Way alone, far more than the few thousand we can see from Earth! The quality or condition of being infinite. They've obsessed over it, and ordered up some of the most powerful sensitive space satellites ever built to answer this question.Astronomers have looked deep at the Cosmic Microwave Background Radiation, the afterglow of the Big Bang. For starters, the fact that we know the observable universe to be 93 billion light-years across is astonishing — that’s a great story in itself, and you can read about it extensively here — but how do we know it? , Is there life on other planets?, Voyager, What technology has been sent into space? Is the universe truly infinite? With Infinite Office, you can put on the headset and be transported to a virtual office space that you can make as big or small as you wish. Designed by Tabane Shinonono, they possess technology and combat capabilities far more advanced than any other weapon system, thus threatening to destabilize the world. Unbounded space, time, or quantity. Is the universe spatially infinite or spatially finite? Edward Teller. We don't even need multiverses to find them. I acted like nothing happened and immediately got off the elevator. Infinite Ricks is the first Multiverse cryptocurrency. Tony Padilla from Numberphile has estimated that number to be 10 to the power of 10 to the power of 70. What Would Happen If You Shot A Bullet On A Train? What Is The Huntsman Spider? Separating the concept of universe and space is a good solution for my poor grey cells. So, space is infinite because space is nothing, and nothing is the only "thing" that can be infinite. However, we have no evidence to suggest that such an “outside” exists, which makes a strong case for the infinite universe theory. Click here to sign in with I was asked to answer this a while ago, and have sat on it trying to think of a good way to put this. In fact, hopefully you'll absorb the powers of an immortal version of you, because if you keep going you'll find an infinite number of yous. It even be infinite, which is much bigger than huge. Usually it's just 'My MSWord doesn't work' or something, but this one really stuck with me. How would we then prove or disprove their ideas? Is the universe infinite or not? Get weekly and/or daily updates delivered to your inbox. That doesn't mean that there's an infinite "space" between zero and one, just that some of the numbers between zero and one are very close to one another. They've searched for evidence that features on one side of the sky are connected to features on the other side of the sky, sort of like how the sides of a Risk map connect to each other, or there's wraparound on the PacMan board. That space is truly infinite - but that we live somewhere within a vast region of galaxies - but beyond that region, there are fewer and fewer galaxies until space is literally empty. Our experts discuss the staggering size of the universe and how we can measure it on Closer To Truth. Light has been travelling towards us for 13.8 billion years this way, and 13.8 billion years that way, and 13.8 billion years that way; and that's just when the light left those regions. We do not guarantee individual replies due to extremely high volume of correspondence. Everyone knows that the universe is huge, but no one could have imagined how staggeringly immense the universe, or multiple universes, may actually be. we respect your privacy and take protecting it seriously, Updated on: 10 Apr 2020 by John Staughton, Gravitational Lensing: What It Is And How It Is Helping Us Discover New Galaxies, What Exactly is Archimedes Principle: Explained in Simple Words, What is Evolution? : either the universe and more valuable than the Blemflark an infinite universe valued...
