What happens once you reach the edge of the universe? Does it end? Do you appear on the other side?

Answer 1

the universe is four-dimensional, but if you can imagine a two-dimensional version then it seems to be something like the surface of a sphere. it is this surface that is expanding. the universe is of finite size yet has no center and no edge. the big bang was the entire universe, and everywhere in the universe was once the big bang.

Answer 2

There could be a sign that says "Dead End". Or it could be a nice beach with hot babes. If you appear on the other side then we might be already looking at objects that have come around the other side. But, when astronomers look into space they see everything expanding like a loaf of bread. So, that would seem to disprove the come around the other side idea. However, there maybe more than one loaf of bread. So perhaps we have multiverse. And you might be able to hop over and have some honey wheat bread then go for a pumpernickel. I prefer banana bread myself. Or maybe there is no edge of the universe. Or maybe this planet is living on the edge of the universe. Which seems more likely as we have all these wars and terrorism disease and suffering. Your question is good my lad. Many people throughout the ages have asked this question and have died without any answers. So, have comfort in knowing that you are not alone in not knowing the answer. If you must have an answer then the bible folks can give it to you. But, they usually accuse you of having "little faith" if you ask too many questions. Good luck.

Answer 3

Okay, let's assume two things here at the beginning of my reply:

1.) To make your question have something approaching a valid answer, let's just **say** that there's an edge to the universe, where everything we know - and a lot we don't - comes to an end.

2.) Let's also assume that there's no Star Trek-type faster-than-light travel involved, as we don't have anything near the knowledge to even formulate how something like that could be made to happen.

That said, I fear that we'd never be in a position to find out if our universe, such as it is, ended or not. For even if there's a boundary to it, and even if it's moving at only a pretty good fraction of the speed of light, having done so for over 12 BILLION YEARS gives us such an enormous distance to travel that we'd never even come close to finding out during the entire length of our species' survival.

If we can't get there, we can't go beyond. If we can't go beyond, the question will have to remain unanswered.

Sorry

Answer 4

You are assuming there is an "edge".

Space might be stranger than you can imagine. Space might be self contained although the human mind is not capable of imagining that.

You can do some curious experiments to illustrate that space can be strange. Take a long strip of paper and give it a single twist and glue the ends together. You will have created a three dimentional object that has one surface and one edge. This is called a Mobius Strip.

Now take the universe in your mind and give it a twist and glue its ends together. Wait! Where are the ends?

Answer 5

Who says the universe has to have an edge? Even if it ultimately ends somewhere, it may be a ball with us inside. Then we will never be able to find an "edge", and cannot reach "the other side" unless we break through.

Answer 6

By the time we reach the edge of the universe the journey will have no doubt warped our concepts of time and space. Any vehicle capable of taking us there combined with the technology needed to support that vehicle and the journey to the end its-self will no doubt make the concept of an end to the universe irrelivant.

Answer 7

There is no edge. Or, if you prefer, the universe is a 3D volume curved in 4D space and you are at the edge right now, just like you are at the edge of the Earth right now. The 2D surface of the Earth is the edge of the 3D curved Earth no matter where on Earth you are. Similarly, everywhere in the 3D universe is the edge in 4D "hyperspace".

Answer 8

It just goes on and on past the limits of the debris from the big bang in to absolute nothingness where even if you travel at the speed of light you won't feel like you're moving because there is nothing else to judge distance or speed by and then you realise that if there is nothing to gauge your existance to maybe none of it is real. Time vanishes and space ceases to be a logical dimension.

Answer 9

you keep shifting forward. because of the fact the universe is consistently increasing. there is no longer something on the different part. yet this does not be a concern, because of the fact the universe is increasing so promptly; it may well be notably much impossible so which you would be able to even catch-as much as the tip of the universe.

Answer 10

Good question but a tough one. I'm gonna guess its a big circle and if you look for the end you will end up right back where you started. If you find out otherwise, please let us all know and we can start a whole cult around it. Cool. PS: I love Pluto.... Down with Pluto non-beleivers!!!!
