What do you think lies "beyond" the Universe?

Question

There must be like a kind of border or line where the "Universe" ends.
What do you think?

I read somewhere that they "estimate" that the "Universe" is 156 billion l/y across.

Thanks! Some good answers so far.

Answer 1

We know from quantum equations that 90% of the Universe is missing. So that means our "Known Universe" is merely a "Local Universe" self contained within some kind of continuum membrane containing the known and detectable 10%, and that there is indeed an "outside" exerting a force on this membrane. We have been able to detect a slower expansion velocity of space the furthest distance away, which shocked astrophysics who predicted that the furtherest reaches of space should be expanding at a faster rate. But this makes complete sense if the Local Universe is self contained within a membrane, matching fluidity experiments conducted in the 1800's by a chemist who realized that fluid in a self contained receptacle actually moves slower against the walls of a container.

So, theoretically, there appears to be a larger "Trans-Universal Superstructure" (TUS) of which our Local Universe is a minor fragment amongst countless other "Multiverses", which existences have been mathematically conjectured.

Answer 2

that is an interesting thought, yet it is impossible. for there to be a place "beyond" the universe, that means that this place has to be, in fact, a place. if it is, however, beyond the universe, that means nothing there exists.
a place is defined as a place that an organic being can travel to, but something that does exist cannot be in a place where nothing exists.

in other words, a place must actually be a place for one to travel there.

in place of your idea, many theorists have suggested that the universe is a "loop" or a "figure eight" shape. in other words, the fabric of space time is connected at all ends meaning that we exist on a particular plane that we cannot travel off of.

imagine an ant crawling on a donut. also imagine (for the sake of this argument) that the ant can only travel across the surface of the donut. this is what our universe is essentially like.

the universe can expand also, so the donut that i refered to eralier is more accurately decribed as a baloon with helium constantly being pumped into it.

some theorists suggest that the universe can expand too far and implode on itself but at this time it is simply speculation.

Answer 3

Why does there have to be something 'beyond' the universe?
It is only on Earth we have the concept of borders. We live with and define our lives with and by borders.
Unfortunately there are two concepts that the human mind has difficulty understanding.
1. Infinity
2. Absolute nothingness.
But they both cannot exist at the same time!
Therefore it is easier to put a picture in our minds that there 'has' to be an end to the universe and there is in fact a border rather than try to fathom infinity or nothingness...

Answer 4

This is a "very" good question, but due to my lack of knowledge & comprehension, I can only guess that whatever lies beyond our Universe must have some form of space or entity for our Universe to exist in it in the first place !

Answer 5

What lies beyond the universe is rather like asking- 'What is north of the north pole?'

Answer 6

Define universe. Do you believe that our universe is a part of a greater Cosmos?

Answer 7

on the history channel they sais that space has enlarged itself,how I don't know.I think it is a spiritual border unseen by the natural eye. of course you know this is a topic with various opinions.
