1 decade ago. Common examples are the infinite-dimensional complex projective space K(Z,2) and the infinite-dimensional real projective space K(Z/2Z,1). 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. 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. There is no “edge” or “end” to it. And so far, there's no evidence they're connected. So, how would you test this idea just by watching the sky? Neither your address nor the recipient's address will be used for any other purpose. While this would make the volume of the universe billions of times larger than we presently can see, it is possible. Get weekly and/or daily updates delivered to your inbox. The information you enter will appear in your e-mail message and is not retained by Phys.org in any form. Also would there be any possibility of interaction between these universes? "This suggests that the universe is infinite in extent; however, since the universe has a finite age, we can only observe a finite volume of the universe," NASA says on their website. It could be much larger than that, but we have no way of knowing. So it could be something like a finite region of space with matter within an infinite region of space with emptiness surrounding the matter. Designed by Tabane Shinonono, they possess technology and combat capabilities far more advanced than any other weapon system, thus threatening to destabilize the world. 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. Short. 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. I was asked to answer this a while ago, and have sat on it trying to think of a good way to put this. The only digital currency that is accepted in any universe and more valuable than the Blemflark. Also … What we know with certainty is that the Big Bang occurred 13.8 billion years ago, meaning that is the age of the universe. 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? Of course they have, you fragile mortal meat man/woman! And if the Universe is finite, well, it's finite. Cite. Why Do Stars Appear To Be Stationary If The Galaxy Is Constantly Moving? There are an infinite number of numbers between (for example) zero and one. This is the main premise for scientists to presume that the universe is still expanding. 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. Will Asteroids Ever Threaten Life On Earth? There are an infinite number of numbers between (for example) zero and one. 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. One hydrogen pile looks the same as the next to me. When you are a kid infinite is a hard number to wrap your head around. Scientists and academics like firm answers and measurable quantities, but when you’re talking about the largest conceivable scale (the entirety of the universe), such definitive answers are often elusive, or impossible to ever prove. Cite. Beyond our Milky Way galaxy lies more than 150 billion other galaxies, each with their own massive amount of stars. 2. the observable universe lies totally in our past. 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. :D This suggests that there is an “outside” to the universe, as though one could theoretically step outside and then observe from outside the system.

Here's how smart they are. What we know with certainty is that the Big Bang occurred 13.8 billion years ago, meaning that is the age of the universe. BrianFraser says: March 26, 2015 at 5:23 PM . What have they based their predictions on? What Is The Largest and Most Powerful Magnet In The Universe? About, Former, Human, Infinite, Only, Stupidity, Sure, Things, Two, Universe. These are duplicate universes inside of our own infinite universe. Whether the Universe is finite or infinite is an important question, and either outcome is mindblenderingly fun. That's a number so big that you can't actually write it out with all the pencils in the Universe. What Would Happen If Earth Stopped Revolving Around The Sun? So if this sounds ridiculous, you know why! It would take the Space Shuttle seven months to fly there. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); In another episode of Guide to Space, we talked: "how big is our Universe". If space were negatively curved, like the surface of a 4D saddle, distant light rays would diverge. Haven't astronomers tried to figure this out? What we are saying is that space is infinite. All of space was involved in the Big Bang, which had previously been compressed at nearly infinite density. Properties of ℓ p spaces and the space c 0 [ edit ] The quality or condition of being infinite. In astronomy and cosmology, space is the vast 3-dimensional region that begins where the earth's atmosphere ends. Or better put, does space simply go on forever? Why Is It So Special? We are the spaces of infinite possibilities. How would we then prove or disprove their ideas? Nobody knows whats at the end of space. So there would be an infinite number of galaxies and planets in an infinite universe. Then I said it all depends on whether the Universe is finite or infinite. This means that, at present, we know that the universe i… Have you ever asked “what is beyond the edge of the universe?” And have you ever been told that an infinite universe that has no edge? Is space filled with infinite energy?. 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? If so since ∞ * ∞ = ∞ is also true, can there be an infinite number of universes, all in the same space? When is the last time you looked up into a star-strewn sky miles and miles from any other source of light. It even be infinite, which is much bigger than huge. Here he clarifies the concept of 'flatness', and explains why we may never get to know whether the Universe is finite or infinite. In our hu-man words, this means 13.8 billion light-years in all directions, the Universe doesn't repeat. No signup or install needed. The difficulty we have trying to imagine infinite space, and infinite time, are at the source of the Big Bang theory. Once you accept that space is not an infinite void but rather a maybe-infinite physical thing with properties, you can ask all kinds of strange questions about it. Consider this. What Is The Huntsman Spider? 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. So, space is infinite because space is nothing, and nothing is the only "thing" that can be infinite. 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. Why Does Your Smartphone Lose Charge, Even When You Don’t Use It? Unbounded space, time, or quantity. Comprehending these numbers is nearly impossible for our relativistic brains, so most people think of the universe as an infinitely large and endless void. This means that, at present, we know that the universe is at least 92 billion light-years across. Two possiblities exist: either the Universe is finite and has a size, or it's infinite and goes on forever. For example, what is the size and shape of space? I believe it is finite from the standpoint of energy-mass. One of the more popular theories for this universal shape is a “closed loop”. (Theories about size of space. Separating the concept of universe and space is a good solution for my poor grey cells. Bradley Monton. The great thing about this mystery, however, is that due to the nature of the universe, we may never be able to truly know the answer! Expansion of universe after the big bang illustration (Photo Credit : Andrea Danti / Shutterstock). The "Macro-cosmos" is boundless, borderless and eternal a combination of space and energy in its multiple forms. 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. The expansion of the Universe has carried them from 47.5 billion light years away. the facts are: 1. the BBT states that the Universe had a beginning (roughly speaking) in our past. Given this theorized limitation, the universe would still be considered finite. Infinite space is boundless, borderless and eternal. Couldn't there be exact copies of yourself living in them? If the Universe is truly infinite, well then we get a very interesting outcome; something that I guarantee will break your brain for the entire day. 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. 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. Click here to sign in with 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. And finding a copy of yourself is just the start of the bananas crazy things you can do in an infinite Universe. After moments like this, I prefer to douse it in some XKCD, Oatmeal and maybe some Candy Crush. 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 space Φ or is defined to be the space of all infinite sequences with only a finite number of non-zero terms (sequences with finite support). If so, since ∞ + ∞ = ∞ is it possible for two universes to exist in the same space but with an infinite distance between them? Edward Teller. If space were infinite, there would not be a beginning, because infinity is defined as a line, not a ray. How Are Satellites Put Into Orbit and Kept Up There For So Long? The key to understanding the ultimate mystery of the universe (The Big Bang) is that it didn’t start from a single point that affected the rest of “space”. Proof that space is infinite. By using our site, you acknowledge that you have read and understand our Privacy Policy If there is a finite probability of something happening (ie. So there would be an infinite number of galaxies and planets in an infinite universe. (Theories about size of space. 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. Is the universe infinite or not? How Big Is It and Does It Bite? How Do Screen Protectors Protect A Phone’s Screen? infinite space, and limited but still expanding universe : good for me. So the interesting part of the universe is finite - but space itself is infinite. The Shape of Space. a planet forming around a star, or a galaxy forming), then in an infinite universe there will be an infinite number of that thing. Apart from any fair dealing for the purpose of private study or research, no The Milky Way is a huge city of stars, so big that even at the speed of … 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! 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. 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. But, as these kinds of things usually go, the answer is both simple AND complicated. Usually it's just 'My MSWord doesn't work' or something, but this one really stuck with me. 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. Is Space Infinite? In the 19th century, Doppler tried to explain an unusual phenomenon about electromagnetic waves: if and observer moves towards or … Space is a term that can refer to various phenomena in science, mathematics, and communications. The initial answer to whether the universe is infinite or finite is a resounding… we don’t know. What Would Happen If You Shot A Bullet On A Train? 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. 0 0. radtadstar. Short. Except, you hydromattecist, you'll pass through places where the configuration of particles will begin to appear familiar, and if you proceed long enough you'll find larger and larger identical regions of space, and eventually you'll find an identical you. The only digital currency that is accepted in any universe and more valuable than the Blemflark. So far, astronomers have no idea what the answer is, but they're working towards it and maybe someday they'll be able to tell us. 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 don't even need multiverses to find them. Although if you had some kind of teleporter, you could teleport to the end of space, you won't be there for long as it will have expanded beyond there already. 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? It can be infinite because everything has an eventual endpoint and space isn't a thing--it's literally the opposite of a thing. 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. And my brain has already begun to melt in anticipation of discussing the implications of an infinite Universe. If space is infinite and homogeneous, then yes; matter is also infinite. This set is dense in many sequence spaces. Infinite space is boundless, borderless and eternal. Your feedback will go directly to Science X editors. 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. Actually, it's probably still not enough pencils. Usually it's just 'My MSWord doesn't work' or something, but this one really stuck with me. If it is spatially infinite, what are the consequences of this? Infinite Space is a 2009 science fiction role-playing video game with space simulation and real-time tactical role-playing elements, developed by Nude Maker and PlatinumGames and published by Sega for the Nintendo DS. It might be easier to explain about the beginning of the universe and … The idea of anything being “infinite” is (once again) very hard for the human mind to comprehend. We do not guarantee individual replies due to extremely high volume of correspondence. Is space infinite? It was the third of a four game publishing deal with Sega. Medical research advances and health news, The latest engineering, electronics and technology advances, The most comprehensive sci-tech news coverage on the web. Mathematically, this usually means no restrictions on the domain or co-domain of the two-dimensional space. None of this has anything to … Does the cosmos go on forever, or is outer space finite? or, by Fraser Cain, Universe Today. Explore this age-old question. part may be reproduced without the written permission. 3. If so, since ∞ + ∞ = ∞ is it possible for two universes to exist in the same space but with an infinite distance between them? That's an "at least" figure. Infinite Ricks is the first Multiverse cryptocurrency. Thank you for taking your time to send in your valued opinion to Science X editors. 1 Recommendation. 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. Listen to Is Space Filled With Infinite Energy? But, as these kinds of things usually go, the answer is both simple AND complicated. Space is infinite as it is expanding all the time. Based on this, our Universe is 93 billion light-years across. Or is Space finite. Space is expanding, so from what we understand space is not infinite, space is just really really big. You can be assured our editors closely monitor every feedback sent and will take appropriate actions.
