And even if it did, you could never go there because it is expanding so fast that the farthest parts are unreachable. Are the galaxies arranged on the surface of a sphere? However, scientists do not know what shape the universe is or what would happen when the photon reaches the"edge" of the universe, if the universe even has an edge. share . Assuming one could reach the edge of the observable universe, what would happen if you take one step further? Since the universe is constantly expanding, and everything around you is older than you are, you must be on the expanding edge of the universe. Just like the horizon on Earth, the cosmic event horizon is a regular place. You're kind of taking for granted that the universe has a stationary edge. 100% Upvoted. ELI5: What would happen if somehow we were able to reach the edge of the universe? Think of heat death as the total opposite of the Big Crunch. Nothing really happens when you cross it. Mar 15, 2019 - What Would Happen If a Nuclear Weapon Hit the U.S.? Beyond a certain distance, light hasn't had time to reach us yet. The estimates would yield very different predictions if Earth happened to be located elsewhere in the universe. share. Gold Member. But some go a step further into the unknown (and probably unknowable), contemplating what lies outside the boundaries of our universe. 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. We only know of the Observable Universe. But the balloon is just one example. 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? 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%. Log in or sign up to leave a comment log in sign up. The universe has no edge. There's no edge, yet that balloon universe has a finite volume. 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. It's just one possibility, however. No. ^ back to top. The effect of this geometry is that looking far enough in any particular direction will cause the same thing to be seen. It *is* conceivable that you might come back into the universe at another point. The science is much less settled on how that will happen. Its outer edge moves at half the speed of light. What happens if you had the ability to go further? Sort by. You are sitting comfortably in your universe… may be not comfortably… because as per the question, you are on the edge…; And you decide to stick your arm out…. Even if we agree that the universe is finite and has an edge, what is at the edge is another topic up for debate. Would you not end up somewhere that exists? 0 komentar: Post a Comment. share. We haven’t even went passed our own galaxy! Being like everywhere else, there’s nothing to notice. One of the strongest theories for the geometry of the universe is that it is like a giant expanding balloon. The Holmdel Horn Antenna on which Penzias and Wilson discovered the cosmic microwave background. Astronomy. Lv 7. If it does what would happen if you went past the edge? When astronomers sometimes refer (carelessly!) Science Advisor. What would happen when an Alcubierre Drive is sitting at the edge of the universe and pointing away from the universe? What would happen when an Alcubierre Drive is sitting at the edge of the universe and pointing away from the universe? This is as far as we can see into the universe. The conventional Big Bang theory states that the Universe is expanding from a point of singularity. There are three options: spherical, flat, or hyperbolic (that is, it curves upward).
