Is there an edge to the universe?

Answer 1

The universe is expanding at a rate of about 80 kilometers per second per megaparsec. So at about 12 billion lightyears away, the expansion rate exceeds the speed of light. That's actually permitted according to Einstein, because it's related to the expansion of space, not matter. So even if there was a brick wall at the edge of the universe, you wouldn't be able to reach it because you can't go faster than light (but the expansion of space can).

Answer 2

There is a definitive answer to this question and and the answer is
"no."

The reason the universe doesn't have an edge is that the quality of space, i.e., measurable distance which of necessity requires a boundry or an end, only exists INSIDE the universe. Since space doesn't exist outside the universe, the universe can't have an edge.

But that's not all. If the universe doesn't have an edge then it can't, by definition, have a center.

Answer 3

The word "universe" means "everything there is". So if the universe had an edge, then there would be an "other side". But then the other side would be part of everything there is. So it would be part of the universe. So the edge would not be the edge of the universe.

It's like asking, is there anything that exists, besides everything that exists?

Answer 4

The two concepts of the universe HAVING an edge and NOT having an edge are equally unfathomable.

If it HAS an edge, then presumably there must be something on the other side of the edge, like most things with edges. Otherwise how would you be able to distinguish the edge? ( i hope that makes sense). If so, what is on the other side of the edge????????????????????????????????????

the other alternative is that there IS no edge to the universe, it just goes on and on and on... and on... and on into eternity. Again, another equally profound idea.


I dunno. I guess i would go with the latter (i.e. that it has no edge, no end) ,since the former seems most impossible

Answer 5

Certainly not !!!

You will get some really strange answers to this question.
I am certain of that.

The largest body of astronomers that I have found so far seem to indicate that the known universe (things that we can see) extends outward from here to any direction (in every direction) you choose about 45 Billion Light Years.
Space continues beyond that but is difficult to measure because you cannot measure or discuss a distance that extends from here out to nothing. So outer space just goes on past 45 Billion Light Years to who knows what.
It certainly is not a brick wall or any kind of edge you could fall off of, as if you would fall off of one here on Earth. Discussions of some kind of edge tell me that you have not opened your mind to consider the true vastness of outer space, and the idea that it might be so big you cannot comprehend the size of it. Believe me when I tell you that 45 Billion Light Years is a heck of a long way away from here. What ever is out there beyond that will never get here, or be visited in our lifetimes, so it is of little importance to the average man in the street.

Answer 6

I read somewhere that the universe is shaped like a donut, so there really isn't an edge. Sort of if you started walking round the World, you could not fall off it.

Answer 7

The only edge is the limit of what we ourselves can see. When our technology grows more powerful, the 'edge' just moves farther away. That is what infinity is all about. It is there, just beyond our reach, the unknown, and forever unknowable.

Answer 8

We sat in the parking lot you and I
Our eyes straight ahead we were fixed on a sky
Where the stars spill down to the edge of the earth and I said
"Could this be the edge of the universe?"

We bared our souls and we shuffled our feet
And we contemplated the passenger seat
While we shared some truth and you quoted verse
From our ledge at the edge of the universe

And I wept for a wound that would not heal
My pain spilling out of your automobile
Then you held my hand
And the stars drew close

Then you lit a smoke and you drew real deep
And the smoke circled over the passenger seat
And I wondered if you wondered about our worth
When compared to the size of the universe

And we wept for a world that could not hear
Our words spilling out of that automobile
Then you held my hand
And the stars drew close

We sat in the parking lot you and I
Our eyes straight ahead we were fixed on a sky
Where the stars spill down to the edge of the earth and I said
"Take me to the edge of the universe!"

Answer 9

No.
The Universe is finite but there is no edge.
The official way of saying this seems to be to say that the Universe is finite but unbounded. It means that if you tried to follow a straight line from here it would eventually lead you back to where you started.

Answer 10

think there is no edge for the universe cause the universe is very vast and no one knows where it ends
