Are we at the periphery of the universe or in the middle? 40

The universe is the sum of all space, time and energy, and from this point of view, of course we are in the universe, and in the three-dimensional space-time, you can't reach the boundary of the universe at all. It's hard to say where exactly we are in the universe. The Earth is relatively "outer" in the Milky Way, roughly two-thirds of the way from the center.

Our universe is a closed model, if it is a membrane relative to the fifth dimension, and a sphere relative to the fourth dimension, we live in the four-dimensional sphere or on a membrane.

In fact, according to the current level of science and technology of the earthlings, it is not possible to determine the position of the earth in the universe, that is to say, the position set by human beings for the earth is only a concept formed in the human brain by virtue of human beings' own subjective thoughts and what so-called science and technology. I've seen a movie in which the protagonist says a sentence (to be continued).

At least we know that in the outer periphery of the Milky Way, the universe does not know what shape it is, and it doesn't matter what the central periphery is.

If only someone knew the answer to this question, they could receive the Nobel Prize.

The universe is a unity of space, time, matter, and energy. It is a synthesis of all space and time.

Do you understand that?

The universe is a closed sphere, and scientists have found that the universe has background radiation, and the background radiation intensity is the same no matter which direction it comes, so it can be said that every point is the center of the universe, or that the universe has no center, then the position of the earth is not easy to determine.

The outer edge of the Earth's universe is surrounded by a thick layer of high-energy "clouds", which are the outer shell of the Earth's universe, a rotating magnetic field that drives all the galaxies in the Earth's universe

I don't know, there is a saying that our universe is like a ball, we can only be on the surface of the ball forever, we can't get to the center, and we can't even imagine it.

Outside the solar system, not outside the universe, the two meanings are the same!

Beyond the solar system is the Milky Way, a flattened galaxy with more than 200 billion stars and countless planets. Beyond the universe, there is actually our distorted three-dimensional universe. Because galaxies, especially black holes, can cause subtle spatial distortions.

A small distortion will eventually connect the two ends of the universe to form a three-dimensional universe that is distorted and connected. So let's say you have a flying machine that travels a billion times the speed of light and flies to the depths of the universe; Fifteen years from now (assuming the width of the universe is 15 billion light-years), you will be able to return to the solar system and back to Earth, of course, tens of thousands of centuries from now (according to Einstein's theory of relativity, the closer you get to the speed of light, the slower the time of light will be, so slow that it almost seems to come to a standstill).
