What is the outer side of the universe like?

As far as science and technology are concerned, we do not yet have the ability to explore what it is like beyond the universe. But according to the bold imagination of scientists, there is likely to be a broader and more inclusive universe beyond the universe.

The outer edge of the universe is also very empty, because the Milky Way alone is already very large. Then there will be a larger inclusion outside, just like a big house, a small house.

The outer edge of the universe should be an oval-like outer ring, because the center of the universe is attractive to celestial bodies, and their trajectory is elliptical, then the outer wall of the universe should also be in this shape.

Of course, the outside of the universe is also the universe, and it is a vast cosmic planet, and galaxies are things that we can't see, which can be said to be very mysterious, and the universe is boundless.

The outer appearance of the universe is also black because there is no sunlight. Everything was dark, and it was especially cold. Sub-zero temperatures can be reached, which is a terrible phenomenon.

The universe has no outside, if the universe has an outside, it has a boundary with the outside, just like our house, which divides the inside and the outside with the house, then what is the boundary between the inside and the outside of the universe? Take the earth as an example, the earth's space is bounded by **? Where is the boundary of the solar system?

As far as human knowledge is concerned, there is no outside in the universe. Even if it does, it is unexplainable by current theories.

There can be two explanations: 1. The universe is infinite, and there is no distinction between inside and outside; 2. Outside the universe is another universe or parallel space-time.

Use your imagination....It's like walking into a desert and treating every piece of sand as a planet, which is roughly what the universe looks like.

Albert Einstein believed that the universe was finite and boundless. The universe was created 100 million years ago by a singularity.

The universe is big**.

Time, space, and matter are all created after the big **, and they are always expanding. Scientists have determined that the observable diameter of our universe is 93 billion light-years.
