what would happen at the edge of the universe
I realize that the universe expands constantly and that we could never theoretically reach the edge of the universe, but putting that aside: What would happen if an observer go just past the edge? Just like the horizon on Earth, the cosmic event horizon is a regular place. Think of heat death as the total opposite of the Big Crunch. Science Advisor. But some go a step further into the unknown (and probably unknowable), contemplating what lies outside the boundaries of our universe. The science is much less settled on how that will happen. save hide report. The universe is expanding, but what's it expanding into? We're not even sure if the universe will come to a firm, defined end, or just slowly tail … Would you not end up somewhere that exists?

Even if we agree that the universe is finite and has an edge, what is at the edge is another topic up for debate. No one really knows. ^ back to top. You're kind of taking for granted that the universe has a stationary edge. Physicists have long studied the nature of the universe. 1 2. biire2u. When astronomers sometimes refer (carelessly!) save hide report. The bright patterns show clumps of simple matter that will eventually form stars and galaxies. share . Staff Emeritus . Sort by. Like all black holes, the huge ones are shielded from view by an event horizon. Logically thinking there is only two possible outcomes: 1) You touch it and you can feel it like an object In this case, if you can feel something, then there has to be something "behind" the edge of the universe. Beyond a certain distance, light hasn't had time to reach us yet. share. We haven’t even went passed our own galaxy! The Shape of the Universe. What would happen when an Alcubierre Drive is sitting at the edge of the universe and pointing away from the universe? What would they see? So there’s no real “edge” to the universe. As the universe expanded, ... Next, they depend on our being at a special spot at the edge of the Milky Way galaxy and they did not suggest the radiation is isotropic. 17 comments. The univere is expanding, but it isn't expanding into anything. What would happen when an Alcubierre Drive is sitting at the edge of the universe and pointing away from the universe? Does the Universe have an end? In a non-expanding Universe, as we covered earlier, the maximum distance we can observe is twice the age of the Universe in light years: 27.6 billion light years.

There is a possibility that the universe is shaped like a 4-dimensional bubble, and if you go far enough in one direction you will return to the same place from the other direction. ELI5: What would happen if somehow we were able to reach the edge of the universe? Scientists aren't actually sure whether the universe is finite or infinite, or even what shape the universe is. No. The title explains it all, I would love to hear answers or ideas to this. The conventional Big Bang theory states that the Universe is expanding from a point of singularity. Explained. One of the strongest theories for the geometry of the universe is that it is like a giant expanding balloon. Its outer edge moves at half the speed of light. There are several schools of thought on this. Assuming one could reach the edge of the observable universe, what would happen if you take one step further? Photo Credit: Wikipedia Therefore, to even dream of reaching the edge of the universe, a spaceship would have to go as close as physically possible to the speed of light, somewhere around 99.9999999%.

And if there is still something out there, then it can't be the edge of the Universe 2) Your hand goes through it If it went through it that means there is still space. The universe is expanding, however, so the round trip would be impossible if limited to light speed. If it does what would happen if you went past the edge?

It is time, not space, which limits our view. 0 comments. to galaxies "near the edge of the universe," they are referring only to the edge of the OBSERVABLE universe - i.e., the part we can see. There's an end ot the universe, but the "edge" implies that there's a line where the universe ends and the not-universe exists. 58% Upvoted. The Holmdel Horn Antenna on which Penzias and Wilson discovered the cosmic microwave background. The universe is ever expanding, and if it's at the speed of light (we don't know it isn't), then we will never reach the edge, or even get any closer to it than we already are. Nothing! Gold Member. But the balloon is just one example. The only present is in your brain the instant you form a thought. share. In simple terms, the space between galaxies is also expanding, which drives the edge of the universe further and further from us every single second. There's no edge, yet that balloon universe has a finite volume. This is, however, unlikely to happen based on current knowledge, since we’ve recently discovered that the universe appears to be expanding at an accelerating rate. Astronomy. For instance, physicists want to know whether or not the universe is infinite, meaning that it goes on forever. 0 komentar: Post a Comment.
