Run towards the end just to appraise your own devotion. I would expect that it would be the same, nothing, not even virtual pair creation until the expansion is large enough to reach your 10000billion light years.

If so, then Ron is incorrect in his "positivist" approach of absolutely denying the existence of anything beyond this horizon. It is the GR space that is expanding. On the other hand this is at the frontier of research and will probably not be settled for a long time. The second reason is harder to convey, but it has to do with the holographic principle and the existence of a "dual description" of a theory with quantum gravity, on the boundary of its space. In an inflation model, you can have most of the external volume still inflating, so that the banging is at different "time" at different places, and in most places, counted by extended volume, the bang never happens. as to say "a hundred trillion! But we don't live in a Newtonian universe, and when you have a relativistic big bang, the way it works is that all points are the same as all other points after a translation and a relativistic boost. With a CC, you would fall past our cosmological horizon, but this is why CC universes are strange--- they have a thermal mixing time, and there is only so long you can travel before you are thermalized or run out of fuel. " It only takes a minute to sign up. Is that actually the case?

I consider nothing as a potential form of vacuum. Now, there isn't really a physical boundary at the edge of the observable (to us) universe, and for most current theories to hold up there needs to be quite a bit more of "universe" past that distance, probably by some orders of magnitude (10$^{23}$ in some theories). This point of view is called eternal inflation. You wouldn't usually cover this stuff until post graduate level. You run, you steal and won't give up a fight. Has the Star Trek away team ever beamed down to a planet with significantly higher or lower gravity than Earth? So it isn't that there is "perfect vacuum" beyond this sphere, there is a visibility boundary which marks the end of the universe as we can ever see it, and for a positivist (i.e. If you count virtual particles then there is nowhere in the universe that is a perfect vacuum in sense that there are no virtual particles present. New Products – Adafruit Industries – Makers, hackers, artists, designers and engineers. Have an amazing project to share? Adafruit IoT Monthly — Matrix Portal, Solar Lawn Sprinkler and more! It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. It seems a bit like your using the cosmological constant problem as an answer to my question , but that is considered unsolved physics I note. Is there perfect vacuum 10000 billion lightyears away? via Universe Today. Microsoft MakeCode — micro:bit version 2 Announced! It Is Time For #ElectronicHalloween 2020!!! However, based on our current assumptions, we can expect space to look similarly to what it looks like in our observable area of the universe (with the same particle density). This is particularly important when piling zeros on top of numbers to make them look more impressive, since then one runs the danger of referring to absurdly unphysical quantities. What is the difference between a journal named "Letters" & "Reviews" in the end? (is there? One has to separate coordinate system space from the General Relativity space. The main counterargument here is simply that there is no working example of holographic duality in which the cosmological horizon is the boundary. for a physicist) this makes it the boundary of the universe, period. Setting a boundary seems like admitting it has a center , that seems mathematicly unavoidable. By the way, I'm aware of the Cosmological constant problem, but that's not what I require as an answer. The point near the boundary has a shorter light cone, and is just very close to the big-bang that's all (looking out is looking back in time). I am not sure how this "vacuum" will be treated in string theory. This Hubble image of NGC 5307 not only makes you wonder about the star’s past, it makes you ponder the future of our very own Sun. The process of a star aging and reaching the end of its life is a long, slow story, punctuated with episodes of rapid change. mick, Ron is stating a position which fortunately is not yet official dogma among physicists, and will never be, among people who actually study anything galaxy-sized or smaller. A planetary nebula is the remnant of a star like our Sun, when it has reached what can be described as the end of its life. The particles have a speed which is proportional to their distance, and this goes all the way to infinite speed in the Newtonian version. (in bytes). Why is my Sieve of Eratosthenes using generators so slow, Famous cases of multiple papers by the same author published in same issue of same journal. If I found two $5 bills on the ground, would it be acceptable to say "$10 are on the ground"? Some billions of years in the future, it will itself become a white dwarf, lighting up the layers of gas it shed as a planetary nebula. No-one who actually studies stars or galaxies is going to believe that they stop existing because we can't see them, of course. The boundary business is difficult to see outside of GR. There's no distance (even "10000 billion light years"), at which the universe hasn't "expanded into" yet. All these extended scenarios are just-so stories, since they either make no predictions for the observable universe (since by definition, we can't see the stuff outside the horizon), or they make statistical predictions based on saying that we live in a typical volume of the extended universe, and these statistical predictions are ridiculously wrong (they predict that inflation lasts as long as possible conditioned on us being here to observe what we observe, and this is false).

http://adafru.it/discord. So the distance is 60,000 trillion miles. This is counterintuitive but true--- the space constant time slices have a translation symmetry, they look the same at every point. Fight to let them know that I'll do anything to prove it.

one light year length , everything was in the universe, but the coordinates to describe the universe are there, even though unphysical. EYE on NPI — Maxim’s Himalaya uSLIC Step-Down Power Module #EyeOnNPI @maximintegrated @digikey, New Products – Adafruit Industries – Makers, hackers, artists, designers and engineers! Stop and let my mind reflect and capture my emotions. Interstellar space, while mostly empty, still contains a good amount of hydrogen and other debris. With perfect vacuum I mean that there are no particles, not even virtual photons. Why do i have more particles in the render than the viewport? The vacuum in quantum field theories: what is it? A planetary nebula is the remnant of a star like our Sun, when it has reached what can be described as the end of its life. Can you elaborate in what ways will this region beyond the observable universe may effect our models? Join us every Wednesday night at 8pm ET for Ask an Engineer! I haven't heard much about vacuum during education is that normal? You are asking about a point explosion not having time to fill all of space, and this is just not how the big-bang works. About 10,000 light years away, in the constellation Centaurus, is a planetary nebula called NGC 5307. @mick: Having a boundary does not mean it has a center, because the boundary is symmetric at any observation point. "1.000.000 Lightyears". If you have further general questions, post them separately.

But the mass came from one point , and is limited to light speed. The first is the philosophically extreme position that if you can't measure it, it isn't real. Consider a point very near the boundary ? Ten thousand times 6E12 equals 6E16. I cannot understand how to properly fry seafood, Why pixels do not weight the same? The sphere you are imagining is then not a boundary between stuff and vaccum, but it is the boundary of the entire universe, and there is nothing, not even vacuum, outside this sphere. You can't trave 10,000 billion light years away and get there "now", you would get there 10,000 billion light years in the future, which, ignoring the CC, means that the universe Hubble volume would have expanded to include where you are. The other answers to this question misinterpret your question. Could a top ranked GM draw against Stockfish using drawish opening lines in classical chess? It seems like your idea of "perfect vacuum" is something like "nothingness", which you definitely cannot find anywhere in our universe. This is complicated a little by the fact that a Newtonian big bang has things rushing out from a single point. — New Products 10/21/2020 Featuring #Adafruit Voice Bonnet for Raspberry Pi – Two Speakers + Two Mics! 10000billion light years is a coordinate system length since the universe has not reached these dimensions. So if your numbers are to mean a size of the universe not yet reached, a mathematical coordinate system, I think the answer classically is perfect vacuum. This is complicated a little by the fact that you can extend the solutions of General Relativity past horizons, so that you can imagine that there is extra space beyond the horizon, at least classically.
