Is there an end to the universe? How long can the universe exist? Will there be a day of destruction

In the past, it was widely believed that the universe was static, existed for an infinite time, and could continue to exist indefinitely in the future. But Hubble's discovery shattered this view, and people realized that the universe had a beginning, and it was not static, and the universe was constantly evolving. Through astronomical observations and theoretical simulations, astronomers can make informed predictions about the possible outcome of the universe.

The universe has been expanding since its inception, and the rate of expansion has gradually increased, driven by dark energy. If the universe of the future continues to expand endlessly as it is now, the final universe will "run out of oil".

In about 100 trillion years, no stars capable of emitting light will exist, not even those with extremely long-lived red dwarfs, and they will all evolve into white dwarfs, neutron stars, or black holes.

White dwarfs and neutron stars also become completely dark after a long period of cooling, and eventually become black dwarfs that cannot emit light. About 1,000 trillion years later, the planet's orbit gradually decays due to gravitational wave radiation, and it will eventually be swallowed up by stellar remnants. Or planets are affected by the remnants of other stars, expelled from their original systems, and roam in space.

Some experimental evidence suggests that the half-life of protons is about 10-34 years, so by that time, the nucleus will gradually decay, and all baryonic matter will evolve into photons and leptons. By 10 40 years, the universe is dominated by black holes, and they will gradually evaporate with Hawking radiation.

By 10,100 years, black holes will evaporate from the universe. In the distant future, the entropy of the universe reaches its maximum and the universe ends completely.

If dark energy decreases in the future, and the gravitational pull of matter dominates the universe, the expansion rate of the universe will slow down, and the universe will change from expansion to collapse. Eventually, the universe was squeezed and returned to the state it was in at the birth of the universe, and then it was reborn again.

However, these are only theories, and we do not yet know what the future of the universe will really look like.

No. Because the universe is generated by the singularity, and the starting point is irreversible, there is no end to the universe.

Everything in the world has an end day, so there will be the universe, but the end of the universe is still tens of billions of light-years.

Philosophy holds that the universe is infinite and eternal, but there are those who believe that everything has a life cycle. Scientifically, current research shows that the universe is being dominated by a currently unknown force, expanding at an accelerated pace.

Of course, there will be a day when the universe will be destroyed, and the energy of the universe will increase by entropy, and one day it will be classified as heat death, but that day is basically equivalent to eternity for us human beings, too long and too long.

First, the universe will exist for at least tens of billions of years. Second, everything in the world will be destroyed one day, but it will only be a long time, and the universe will also be destroyed. It's just that the process will be long, long.

The universe will always exist, there will be no day of destruction, even if it is really destroyed, it is not really destroyed, it is a restart, and new life will start to grow in the universe again.

The universe is mysterious, and so far mankind's understanding of the universe is still only partial. The mystery of the origin of the universe is still in the **, and judging from the current state of the universe, there is no one definite answer, and everything can only be guessed. There are countless stars in the universe, and they all have their own modes of operation.

How did the universe come into being?

The most convincing theory is that 13.8 billion years ago, a singularity **, the universe was born, it expanded infinitely at the same time, more and more stars emerged, gradually possessed space, time, matter, and also formed major galaxies. There was once an American scientist who calculated the end date of the universe, and many people wondered, does the universe also have an end date? The universe also has an "end day"?

American scientists have calculated the valuation, and the black dwarf may become a witness!

Kaplan calculates the end of the universe.

Physicist Kaplan uses a large amount of data analysis, in his opinion, the universe has an end date, when the last batch of stars to the end of evolution, causing a supernova explosion, the universe will enter a state of dead silence, then the universe will fall into a dark world that cannot see five fingers, it is estimated that only black holes are left, he gave the end date to shock everyone, according to his calculations, he believes that the end of the universe is about 10 32,000 years later. According to this statement, there is still a long time before the end of the universe. The question arises again, what is the supernova explosion?

When the evolution of a star is nearing its end, it triggers an intense **, which is short in time, but emits an astonishing amount of energy that lasts for months before gradually disappearing. Kaplan also believes that the first batch of stars that disappeared are very massive, because the more massive the star, the shorter the lifespan, and the number of black holes will increase after the supernova explosion of the massive star, and finally only a group of small stars will be left, and at the end of the day, it will evolve into a white dwarf, and when the brightness disappears, the supernova explosion will follow, which is a never-ending cycle.

What will it look like after the end of the universe?

The black dwarf no longer emits light because it is a star in its own right, and nuclear fusion reactions are constantly taking place inside it, producing large amounts of iron. Since there is no way to reassemble new elements, there will be a supernova explosion, and the cycle will continue, and the universe will become a dead silence. There will be no more life in nature, and the universe will usher in an unprecedented end date, so what will the universe look like after the end?

This is a process that repeats itself, and may become a singularity, and then through a big ** into a new universe, opening a new round of **evolution. Our knowledge of the universe is too shallow, and the end of the universe may be the time when it begins again. It is in an endless cycle process, which is the main reason why human beings can never understand the universe, it hides too many unknown secrets, even if human beings have explored the universe, they still only know about it

According to this statement, there is still a long time before the end of the universe.

Scientists explain that there is a universe, and by studying many galaxies, we can know when the universe ends.

In fact, the universe has an end date, and the calculation method of American scientists is actually based on the daily energy consumption of our human beings, and then calculates our time to continue to advance to get the result.

The universe is mysterious and unattainable. So far, humanity has only a one-sided understanding of the universe. The mystery of the origin of the universe is still being discussed.

From the current state of the universe, there is no definitive answer, only guess everything. There are countless stars in the universe, and they all have their own way of working. How did the universe come into being?
