When the universe was born, it made several galaxies, how many galaxies there were

If the universe is a finite space, then what is it called outside, so the universe is infinite, and the galaxies created are beyond the reach of science now, let alone several!

The balloon theory is good, but it is equivalent to admitting that the four-dimensional space = =

To say that the universe is infinite is completely self-deception, and it cannot be explained that it is infinite? Then the ancient people still thought that the earth was infinite.

How many are really never counted.

In the universe, there are about 2 trillion galaxies, how were galaxies born?

With the continuous development of science and technology, there are about 2 trillion galaxies in this vast universe, how did galaxies come into being? Do you know that let's talk about it together, the universe is too large for us humans to fill in with our cognition, because we humans are considered small beings in the entire universe, and our current human exploration of the entire solar system is still in the stage of hard exploration. For the universe, our human beings are still relatively lacking in the current level of cognition, so they cannot have a good understanding of the entire universe.

In the same way, there are only a few galaxies in the universe that you can count with your naked eye.

If the distant universe and the neighboring universe have a similar structure, which is one of the principles of modern astronomy, then distant galaxies and neighboring galaxies also have the same structure. What will it be? If you think about it, a drop of water has a billion molecules of water, which is more than the number of galaxies in the universe, and the molecule of water is made up of one oxygen atom and two hydrogen atoms, and a drop of water has three billion atoms in the world.

The sun is our only star, and in addition to the earth, there are also these seven planets in the solar system, as well as a large number of asteroids, comets, dwarf planets and meteorites.

In this long period of time, scientists have thought of many ways, through radio telescopes to search for possible signals of extraterrestrial civilizations in the universe, and launched the Voyager spacecraft to search for extraterrestrial civilizations outside the solar system. The Milky Way is a giant spiral galaxy with the Sun orbiting the galactic center at a speed of 250 km-seconds for a period of about 100 million years. Regarding the age of the Milky Way, the current prevailing view is that the Milky Way was born shortly after the birth of the universe, and even if there are 2 trillion galaxies, you can still invoke this paradox and say that in each direction, you should see a galaxy, but that is not what you can see.

This theory seems more plausible than the pure ** components of matter and energy in the universe, just like us humans, we did not exist a long time ago, and everyone was raised on the premise of a fertilized egg. There are more galaxies in the universe, just next to the Milky Way, there are more than a dozen galaxies, some of these galaxies are much larger than the Milky Way, some are far smaller than the Milky Way, and the distance between each galaxy is very far away, isn't it? From the above, you can get a general idea of what is going on.

Is humanity currently technologically powerful? Standing in the history of human civilization, our strength now far exceeds that of the handicraft era before the industrial age.

The large amount of gas left over in the universe has created a large number of black holes, which introduce gas into their own range, and these gases slowly evolve into stars around the black hole, forming galaxies.

I don't know how it was born, many people are speculating that a big ** happened, so there are a lot of galaxies.

It is mainly through the structure of the universe and the structure of galaxies that the system of galaxies is formed, and the trajectory of galaxies is born.

Because of the rotation of the universe, coupled with some dust in the universe, it fused together to form such a galaxy.

The farthest galaxy that Hubble can see is about 13.7 billion light-years away, and astronomers estimate that there may be more galaxies at 15 billion light-years. This is the boundary of the universe as we know it.

Recently, some astronomers have proposed that the radius of the universe is 46 billion light years.

The Hubble telescope has completed its mission and is about to be replaced by a larger and more advanced telescope, this behemoth with a diameter of 30 meters is jointly developed by the United States, China, India and more than a dozen other countries.

There are more than 300 galaxies in the sky in the sky as large as the moon, and there are about 7 trillion galaxies in the whole day.

According to Einstein's theory of relativity, the universe is "finite and closed", and the universe has no outside.

The answer to the universe can be adopted on the first floor, because human beings are constantly exploring the universe and have not seen the edge, and the total galaxy only refers to the range that human beings can observe at present; But if you want to delve into the meaning of the word "universe", the answer on the second floor is very accurate, "universe" is a spatial concept, from top to bottom: universe, world, system, system; "Universe" is the concept of time, from top to bottom: Universe, Generation, Era, and World; For example, "Jurassic" refers to that era, while "Jurassic" refers to the strata of the corresponding era, etc.

False, the total galaxy is the universe that human beings can observe at present, and it is only a part of the universe.

No, the total galaxy is the universe that humans discovered, and I was in my freshman year of high school, and it was really good to learn it in my freshman year of high school physics books.

Total galaxies can refer to the visible universe or the known universe, with a radius of 14 billion light-years, while the universe is a connotation of space and time, with no boundaries.

Wrong. First of all, we need to know what the universe is, that is, time, space, all matter and energy. Total galaxies, on the other hand, speak only of matter (including some of the energy). It can be seen that in addition to the total galaxy, there is space-time and energy.

The universe is a unity of space, time, matter, and energy. It is a synthesis of all space and time. "Yu" represents the upper and lower four directions, that is, all the space, and "Zhou" represents the past and the present, that is, all the time.

Because the total galaxy is a generalization of the unknown universe by human beings, the real universe is far from being known at the current level of science and technology.

No, but both of these concepts are broad. Some say that the total galaxy is a part of the universe, and some say that the total galaxy is a celestial body one level higher than the universe. It's not the same thing anyway.
