What does the outside of the universe look like?

This requires us to first determine the meaning of the boundaries of the universe. Take a straight line as an example, there can be other straight lines on both sides of it, so that in addition to the four-dimensional universe, there can also be other universes and our universe composed of five dimensions. And the two segments of a straight line can be extended infinitely, so our universe can also be infinitely extended in both directions of time and space.

But the above is only the universe that I can infer with common sense, but this common sense does not necessarily apply to the universe measured by time and space.

Whatever it looks like, it's certainly not a place for people to stay.

There is no such thing as an outside, an inside, ......... universe

The absence of time for extracosmic causes is meaningless to observers like us.

According to human understanding, "inside" and "outside" do not exist for the universe at all, and human thinking and consciousness can only exist in the four dimensions, while the universe has eleven dimensions, and for other dimensions, human beings cannot understand or describe them at all

There is no outside in the universe, as long as there is space, where there is matter, there is a universe, so the universe has no outside.

We are haunted by time and space.

The trinity of matter, space, and time.

Its big has no outside, and its small has no inside.

Everyone on earth wants to know, but they don't know ......

It is now known that the Earth is one of the eight planets in the solar system, which is insignificant and <> in the solar system with a diameter of 1 light year

The solar system is one of the 200 billion stars in the Milky Way and <>

There are countless galaxies in the universe, and the real universe is even more subtle to know what it looks like, guess it is.

Human beings simply cannot run to the edge of the universe, and it is impossible to see the true face of the whole universe. According to the multiverse conjecture, there should be many parallel universes out there that are almost the same as ours. That is to say, if the universe is one person, there must be many identical people and animals, and if it is one cell, there must be more cell worlds.

Some scientists hypothesize that the universe ran out through black holes, wormholes, and white holes.

However, no one has yet been able to discover the existence of wormholes. In this way, no one outside the universe can know yet, and what we know now is only a tiny little bit of the surface of the universe. The argument about this side and the other side is the concept of solid geometry, is the universe considered solid geometry?

That position is on this side?? to be able to call the other side.
