Is the universe infinitely large 5, the universe is not infinite

There are many theories about whether the universe is boundless or boundless. With the continuous development of astronomy, mankind's understanding of the universe has been deepened, and the observable universe has been gradually expanded, and now the farthest quasar observed by telescopes is nearly 20 billion light-years away. And this record will continue to be broken.

Some astronomers estimate that more than 90% of the universe is dark matter that cannot be seen with telescopes. They believe that neutrinos are important dark matter "candidates". Scientists have successively discovered through experiments that neutrinos may have mass.

If this conclusion turns out to be correct, it will have a great impact on the universe. Because if neutrinos have mass, then the universe is finite, and the universe will change from expansion to contraction in the distant future.

The size of the universe is based on the "big ** cosmology", the universe is created by a mass of matter, after the matter explodes, the fragments spread around, expand and expand, in this expansion process formed many nebulae, galaxies and other stars, so the formation of the universe where we are. When the universe expands to a certain time, it begins to shrink and return to the state before the first time, and these substances continue to gather and separate, repeating the big ** and the big collapse, which is endless, and scientists call it "oscillating the universe".

It is now generally accepted that the universe is a finite and boundless three-dimensional space, that we can move in the universe, but we will never find the boundaries of the universe, let alone leave our own universe, and that our universe is only one of many universes, and there are many other expanding universes beyond the boundaries of our universe that we cannot see.

Let me tell you, the progress of mankind in quantum physics in the past two years has confirmed that the universe is likely to be boundless, because the continuity of time and space is like an ant crawling on a curled piece of paper. And beyond the universe is likely to be infinity and the universe, because at present, it can be concluded that our universe is in 11 dimensional spaces, and there are 12 dimensions outside the universe.

The astrophysics of the landlord is still in the thinking of high school students! It's okay to look at special relativity, general relativity, and notes on quantum physics! You can follow up**.

I don't think the universe is infinite, the universe is an invisible edge (because scientists say the universe is mostly made up of black matter) sphere, it also works, and outside the universe is another alien dimension!!

The universe is slowly expanding, and the universe is also formed by the big **, but remember that the temperature of the universe is changing! The bigger it expands, the colder the universe will become, and whether the earth will be able to support it until this day is not the Tao! The temperature of the universe affects everything!

Whether you are asking questions or spreading knowledge.

The universe is finite and unbounded, and according to the theory (expansion theory) the universe is very large, but we can only see a part of it, and the appearance of the universe is particularly flat. For example, the Earth looks very flat from the surface, but it looks like a circle from the perspective of the universe. From a distance, you will know that the horizon is curved.

The universe is vast. It includes the earth we live in, the solar system.

All the planets, and all the stars floating in the night sky, even galaxies that are too far away to see.

Not so long ago, it was believed that all the stars floating in the night sky existed in the universe. And Edwin Hubble changed that perception. Hubble's discovery is wonderful, the Hubble Space Telescope.

The name is also ** to him.

The size of the observable universe is known. His area is 93 billion light-years, a distance that is a helpless number for the astronomers who discovered it.
