Who knows what s outside the universe? What the hell is out there

Outside the universe is a system composed of more universes, and it can continue to be divided, just as atoms can continue to be divided into smaller ones, if the maximum has a boundary, and the smallest also has a boundary, I guess that if the atoms continue to be divided, there will be something like "universe", and then there will be "galaxy" and "earth", and the universe may be divided into "atoms", "cells", "cell tissues", "organisms", "earth", "galaxy", "universe" and so on.

Do you think the mathematical view that a straight line is considered to be infinitely long, but the ends of a straight line coincide at infinity? If you dig a little deeper about the universe (space and time, dimensions, etc.), you won't be bothered by the question you asked.

Albert Einstein put forward the idea that the universe is "bounded", that is, the space of the universe is finite, but you cannot find its boundaries. So there is no need to talk about anything outside the universe now, because according to our definition of the universe, all matter, energy, space, and time are all part of the universe.

Here's a very interesting corollary from Hawking's brief history of time.

There can be no infinite universe.

If the universe were infinite, then the light of each star would end on the surface of another perseverance, so that the light emitted by the stars would be as bright as the sun. Even if it is hindered by other non-luminous substances, these substances will be heated until they glow like stars, which in fact does not happen because there is day and night. The only explanation is that there can simply be no universe of infinite size, either in time or space.

Our present universe must have been born in a finite past, and stars must have begun to shine in a finite past. In short, the universe has not reached thermal equilibrium. This is proved by Hubble's discovery, which is the famous universe of the great **.

Albert Einstein described a multidimensional space-time. That is to say, the universe is finite, but there is no boundary, just like the surface of the earth, although it is limited, but there is no boundary, but the surface of the earth is two-dimensional, and the universe is four-dimensional.

If you're interested in this question, you can explore it in the near future. If you're interested, you'll be able to get unexpected results. I firmly believe in !!

There is no right answer yet, and Goo Hawking says that such a universe is a multiverse.

Outside the universe should be another unknown space, and there should be no more darkness, because after the darkness is the light.

I don't know exactly what's out of the universe, but there's one thing that definitely is, and that's darkness, darkness as far as the eye can see!!

According to "Men in Black", it's glass.

What do you say on the 8th floor? Hyperspace?

People will go to hyperspace after death, which broken book says?

The double springs on the 4th and 5th floors are really interesting.

Men in Black doesn't say it's glass, it just looks like glass.

The universe refers to the existence of "time is infinite and eternal, space is boundless, and mass is infinite and eternal". Since there is no boundary, how can there be an outside? Outside the universe, what you know is still the universe. (Maybe it's a parallel universe).
