The difficulty we have trying to imagine infinite space, and infinite time, are at the source of the Big Bang theory. 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. Long time lurker, first time poster, yadda yadda. 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? For example, what is the size and shape of space? Have people estimated…: Is Space Infinite? 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. John Staughton is a traveling writer, editor, publisher and photographer who earned his English and Integrative Biology degrees from the University of Illinois. What Would Happen If You Popped A Balloon In Space? "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. Listen to Is Space Filled With Infinite Energy? 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". What Would Happen If You Shot A Bullet On A Train? However, we have no evidence to suggest that such an “outside” exists, which makes a strong case for the infinite universe theory. Science Technology Today. The Shape of Space. Discussions around the Big Bang, the size and shape of the universe, the potential for multiverses, dark energy, dark matter and dozens of other enigmatic subjects continue to engage and fascinate experts who spend their lives staring at the stars. Wouldn't that mean that there could be thousands of planets just like earth with actual people living inside them?

A theoretical infinite Universe in space and in time would produce an infinite observable universe as well. Get weekly and/or daily updates delivered to your inbox. Bradley Monton. 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. It was the third of a four game publishing deal with Sega. Our experts discuss the staggering size of the universe and how we can measure it on Closer To Truth. ties 1. If it is spatially infinite, what are the consequences of this? a planet forming around a star, or a galaxy forming), then in an infinite universe there will be an infinite number of that thing. Usually it's just 'My MSWord doesn't work' or something, but this one really stuck with me. Quotes to Explore The science of today is the technology of tomorrow. infinite space, and limited but still expanding universe : good for me. There are an infinite number of numbers between (for example) zero and one. On a perpetual journey towards the idea of home, he uses words to educate, inspire, uplift and evolve. An indefinitely large number or amount. 3. 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. Also … Mathematically, this usually means no restrictions on the domain or co-domain of the two-dimensional space. This document is subject to copyright. 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. (Theories about size of space. 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. Imagine this in terms of our own planet; up until a handful of centuries ago, people believed that the world was flat, since they could only see the horizon, and were unable to witness the curvature of the planet to recognize it as a sphere. Will Asteroids Ever Threaten Life On Earth? It might be easier to explain about the beginning of the universe and … Infinite space is boundless, borderless and eternal.

Two possiblities exist: either the Universe is finite and has a size, or it's infinite and goes on forever. Cite. 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. 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. Common examples are the infinite-dimensional complex projective space K(Z,2) and the infinite-dimensional real projective space K(Z/2Z,1). Unbounded space, time, or quantity. 3. the speed of light is finite. Beyond our Milky Way galaxy lies more than 150 billion other galaxies, each with their own massive amount of stars. Short.
