What is the name of the thing the universe is expanding into?

Answer 1

The thing the universe is expanding into does have a name, and that name is HYPERSPACE .

The universe is not just space, but spacetime and it is curved by its own mass. Spacetime is distorted at high velocities and in high gravitational fields.

In the beginning spacetime was nought. Neither past nor future, nor up nor down; no "across" in any direction whatsoever. Then spacetime just started expanding and it still is: You could say it's expanding like a hypersphere with the universe on its surface.

If planet Earth were expanding like the universe, we "flat Earth dwellers" would see every single object around us moving uniformly away from us HORIZONTALLY. Without our intuitive understanding that the Earth is really a sphere, we would have a hard time understanding what the ground was expanding into. What would we say the ground was expanding into? The Horizon? Infinity? More ground?

We understand that Earth is a globe, and armed with that understanding, we would say Earth is expanding INTO SPACE (not into more flat earth).

Well, the spacetime universe is a little like that, so it's expanding not into more space, not even into more spacetime, but rather into some superior polytopic form, an object occupying hyperspace in some superior dimension.

It's complicated.

Answer 2

if you were a slow, two dimension scientist, living in the surface of a very fast expanding balloon, What would be outside the two dimensions you know? Nothing that you can see or feel.
The Universe is like a three dimensions surface balloon expanding... No easy to imagine! But if you want to understand how was the beginning of the universe, from nothing! (before the universe, there was not space, time, energy or matter.!) you have to use a religion to understand it.
At the beginning, without a know cause, in a no space/time/energy/matter 'place', a huge energy started to expand in a expanding time and space. Latter the energy creates matter but not antimatter!. (hydrogen, helium... galaxies, stars, elements, life...) And all was under a set of natural laws, with very useful exceptions. A great design!

Answer 3

Your question indicates a fundamental misunderstanding of the nature of reality. Spacetime is a property of the universe and so it's logically inconsistent to speak of space "outside" the universe or time "before" the universe. These simply do not exist at all.

The expansion of the universe is the expansion of space ITSELF, not the expansion of the borders of the universe "into" something else. For that reason it is not a violation of General Relativity that the furthest reaches of space are expanding away from us at faster than the speed of light; this is not real motion, since the objects at both ends are basically stationary with respect to their local patches of spacetime.

Answer 4

The Universe is all of the things in "SPACE."

All of the things in space are moving farther and farther apart. So the Universe is expanding. Space has no dimensions. It
is not expanding. Consider that you cannot measure between nothing and nothing.

Answer 5

For all our experience, we can't know of any *thing* that's outside our universe. While we can measure the expansion of universe, we can't know what it is it's expanding into.

Answer 6

It's called "Nothing".

I believe people must have said it thousands of times just since I am here. Obviously, either this is a troll question or you are not reading the responses before asking a question.

Answer 7

Why do people ask these types of meaningless and stupid questions and think they're being smart? My favorite still so far is "what is the speed of dark?" LMAO

Just listen to what the first answerer said.

Answer 8

There is no such thing.

The universe is all there is, including all the space there is. There is no "outside" to be expanding "into." "Expansion" means that more space is being created.

Answer 9

Infinity?
