There are too many stars in the universe to count, so why does the universe seem so cold and dark?

Although there are too many stars in the universe to count, the light and heat emitted by them are greatly diluted in the huge cosmic space, and the universe itself is expanding, which is why the universe we see now is so cold and dark.

Because the universe is too big, there are too many unknowns, and the size of the universe is unknown to us, so it looks dark.

The main light in the universe is the stars! To date, the universe that can be observed by humans is 93 billion light-years in diameter, which contains about 100 billion galaxies, each of which contains at least 100 million stars, for a total of about 100 billion billion stars.

Many people think that the life of stars is infinite, but humans have discovered that a star that was once observed has disappeared. Hundreds of stars disappeared in 50 years, an event that caught the attention of many astronomers. So why do stars disappear in the universe?

I am also very curious about this phenomenon, because it is believed that the life of a star is very long, and its volume is also very large, even if it burns the core, it can burn for a long time, and it is impossible to disappear hundreds of stars in 50 years. But the life of stars is not infinite, and hundreds of stars have disappeared in 50 years, all of which are huge red supergiant stars that disappear when they run out of fuel. So when the fuel of the stars is burned out, then the stars will lose their life and will disappear from the universe.

Therefore, the term of any life is limited, not infinite, if this life has come to an end, we must also accept it calmly, do not forcibly retain, and in terms of human science and technology, it is also impossible to retain the life of the stars, we can only watch the stars disappear.

In fact, scientists were also very shocked when they found that the stars disappeared, and then scientists took out the old astronomical data images discovered in 1950 and found that 100 stars had disappeared strangely in this half century, and this discovery went against common sense and attracted the attention of many astronomers. So scientists understand that the life of stars is also limited, and after the burning core, the star will disappear and will not reappear. From this we can also see the laws of the universe, the universe is the same as the earth, the stars are like human beings, human beings will lose their lives and disappear on the earth, and stars will disappear into the universe.

Because stars have a lifespan, there will be a lot of changes in the long course of history, and there will also be star collisions, so it will cause the star to disappear.

This is because the fuel of a star is finite, and if the star burns up all the fuel on the planet, it will disappear.

Because stars have a lifespan and when they run out of energy, they evolve into white dwarfs, so they disappear.
