Will the universe disappear and what is it made of

Yes. Big**! The universe we observe now has a boundary of about 10 billion light-years.

It is made up of numerous galaxies. The Earth is an ordinary planet with life in the solar system, while the Sun is an ordinary star in the Milky Way. How did the stars, planets, comets, galaxies, etc., that we observe, come about?

The cosmology holds that the universe as we observe it, in its early days, is concentrated in a singularity that is very small, extremely hot, and extremely dense. Around 14.1 billion years ago, the singularity occurred after the occurrence of the big **, which began the birth history of the universe in which we live. The temperature of the universe is about 100 billion degrees.

The main forms of existence of matter are electrons, photons, neutrinos. Later, the substance spreads rapidly and the temperature decreases rapidly. 1 second after the big **, it drops to 10 billion degrees.

14 seconds after the big **, the temperature is about 3 billion degrees. After 35 seconds, at 300 million degrees, chemical elements begin to form. The temperature keeps dropping, and atoms keep forming.

The universe is filled with clouds of gas. Under the influence of gravity, they formed a star system, which in turn evolved into the universe today. About 5 billion years ago, all the matter in the universe was highly dense at one point, with extremely high temperatures, so there was a huge **.

After the big **, matter began to expand outward, forming the universe we see today. The whole process of the great ** is complex, and now we can only describe the history of the development of the universe in the past on the basis of theoretical research. In these 15 billion years, galaxy clusters, galaxies, our Milky Way, stars, solar systems, planets, moons, etc. have been born.

All the celestial bodies and cosmic matter that we see and cannot see now form the present universe have formed the present cosmic form, and it is in this cosmic evolution that human beings were born.

Yu"Refers to space,"Celestial"Refers to time. The universe is a material world that is boundless in space, has no beginning and no end in time, and moves according to objective laws.

Cosmic generalization. The universe is a unity of space, time, matter, and energy.

The universe is the general term for all things, the unity of time and space. The universe is a material world that exists objectively and does not depend on human will, and is in constant motion and development. The universe is diverse and unified; diversity in the diversity of material manifestations; Unity lies in its materiality.

No. It is composed of many nebula-like stars, and even space.

Slowly getting bigger, slowly stabilizing, and then** a new universe is forming.

Many theories suggest that the universe comes from a singularity, and that the singularity is a form in theory. The density is infinite, the temperature is infinitely high, the mass is infinite, and the volume is infinitely small. When these values break through the critical point, the universe is created.

The universe has been expanding for 15 billion years, and now human beings have very little understanding of the universe. It is impossible to predict the future of the universe. But the universe will eventually begin to shrink after breaking through its infinite volume, and eventually revert to a singularity.

But this time will not be much faster than the expansion time, and even now the universe will start to collapse and the universe will continue to exist for 15 billion years. There are still 5 billion years left compared to the helium flash of the sun around us, and there is still enough time for humans to prove that they are a race capable of continuing to exist.

The universe has been formed for a long, long time, and we are not able to ** now, and everyone generally agrees on the formation of the universe as "the universe is big". The solar system we live in is a very small being in the universe, let alone a tiny Earth in the solar system. The universe has been born for a long time, let alone the birth of the universe hundreds of millions of years ago.

There are many theories about the birth of the universe, one of which is that a singularity in the universe was created by a large **.

The birth of the universe has been a concern since our ancestors, who once did not understand astronomical knowledge and regarded all this as the role of "God". But with our ongoing knowledge and understanding of the universe, we are also trying to find out the reason for the birth of the universe. Now there is a saying that a big ** occurred in the universe, and the big ** produced a lot of energy, and these energies later became stars one by one, which is the universe we know now.

The universe is so big that it is difficult for our current science and technology to fully understand it, and we can only solve those mysteries through a little effort. The birth of the universe is a very magical event that requires great energy.

The universe has been created for a long, long time, perhaps longer than we guess. The timing of the formation of the solar system is already very impressive, not to mention the birth of the universe. Because of the birth of the universe, there will be a solar system, there will be the earth, there will be us human beings, we are very small in the universe, the universe is too big, and our current level of technology can not even know how big it extends to**.

The birth of the universe and the reasons for its birth still need some exploration and research from us, after all, there are so many mysteries in the universe that we cannot fully understand. But the development of human beings is endless, and its mysteries can be discovered eventually.

The universe was born 100 million years ago, and after the universe was large, the universe formed many planets and the vast starry sky!

The universe existed 15 billion years ago, and it is now widely accepted that the theory of the formation of the universe is the theory of the universe. It is that the matter of the universe gathers together, and the energy gathers to a certain extent, and the universe cannot bear it, so it produces **, and finally produces water, forms the atmosphere, dust, and then gradually evolves into asteroids, etc.

The universe appeared 13.8 billion years ago, and it was the quantum fluctuations in the universe, and the singularity was not stable, which led to the occurrence of the universe **, and then began to form galaxies.

At present, according to scientists' speculation, the universe was formed 15 billion years ago, when a large **, and the singularity with infinite mass and density were formed.

The universe existed hundreds of millions of years ago in a huge formation.

The universe existed tens of thousands of years ago, and the formation of the universe began from a cardinal point.
