There is no end to the universe

There must be at the end. It's just that the current technology can't detect it, and it can't guess what the end will be. It's as if the ancients couldn't know what the edges of the earth were.

When the ancients reached a certain level of technology, they knew that the earth was actually a sphere. When our science is advanced enough, we will definitely be able to detect the end of the universe. But I guess the universe will also be a circle.

But it's not a geometric circle, I can't say what it is, it's just a vague concept. In any case, it means that we are moving in a straight line towards a fixed coordinate in the universe, and if we are fast enough, we can also return to the starting point. It's just that this one doesn't go back to the starting point like the one on the earth who is "in the opposite direction", but through the fourth dimension of "time".

Think about it, if the earth is flat, then we can't go back to the starting point if we don't change direction. But because the earth is not a plane, but a sphere, that is, it has a third dimension, which is a three-dimensional plane, so we can also return to the starting point. What it means is that you can go back to the beginning by leaving the second dimension behind and entering the third.

So what happens when we leave the third dimension behind and enter the fourth? I think it's also possible to go back to the beginning. And a complete "circle" of this fourth dimension is the end of the universe.

If you leave the fourth dimension and enter the fifth dimension, you should be able to enter another universe, or another realm of this universe.

The universe is finite and unbounded, just like a balloon, we are inside the sphere, the space of the sphere is limited, but we can never go to the end in it, just like walking on the surface of the earth can never reach the edge.

Flying in the universe, even if you have reached the farthest point of the universe, you cannot fly out of the universe, because space is distorted, even if you keep flying in one direction, in distorted space, the flight path looks curved from other spaces, and it flies around the farthest part of the universe. Flying inside the universe, no matter which direction you go, will eventually return to the starting point.

There is no end, the universe is an infinite loop system.

But now we can think of zero and infinity as two theoretical boundaries, but space-time will be reversed repeatedly at these two meaningless boundaries, like a beating heart.

There is volume, there is no end.

It's like running on a 400-meter track, if you don't pull the line, there's no end.

There is no end to the current understanding.

There is an end, about 15 billion light-years from Earth.

If there is, there is, and if there is none, there is none.

At present, scientists can observe the universe of 13.4 billion light years, and they put forward three major conjectures, the first multidimensional universe, Hawking believes that there are countless universes outside our universe; the second void space, the universe is expanding at a speed beyond light, beyond the reach of human beings; In the third life space, we may be the internal blood meridians.
