Obviously the cosmic environment is very bad, why can t we feel it?

The scope of the universe is outrageous, and according to the research results, the maximum universe that can be observed by humans is 93 billion light years, the speed of light is 300,000 kilometers per second, and one light year is the distance that light travels in a vacuum for a year.

In the universe, some people may think that since space is a high-vacuum environment and there is no water, spacecraft should not corrode like on Earth. However, this is not the case. Space not only has the radiation left by the universe, but also various celestial bodies are also radiating electromagnetic waves outward, and even many celestial bodies also radiate high-energy particles outward to form cosmic rays.

The cosmic environment is very harsh, in the universe there are often supernovae**, black hole devouring events, and countless comets, asteroids, meteorite moments, the mysterious black hole in the universe can swallow everything, including planets, light.

The distance between us. Take our solar system is about 2.60,000 light-years away from the center of the Milky Way, so if our solar system wants to revolve around the Milky Way, the distance it needs to move is about 10,000 light-years and it will take 100 million years, which is too unimaginable, to know that maybe this circle down, whether human beings are still there is not necessarily, and the solar system will fly at a speed of 1000 trillionths of a circle per hour, at this time, there may be extraterrestrial civilizations in galaxies outside the Milky Way. When they want to see the whole galaxy, our galaxy rotates very slowly.

I can't feel it, but it's just because we're too small.

Although the cosmic environment is very harsh, we can't feel it because of the protection of the atmosphere.

This is because we are so far away from the universe that we don't feel it.

Because we are so far away from the universe, we are only protected by an asteroid in the solar system, a system in the universe.

Because the universe is so big, it's hard for us to feel the slightest change.

Because we are on Earth, we are isolated by the Earth's atmosphere and protected by the Earth.

For example, the cosmic environment is very harsh, and there are often supernovas**, black hole devouring events, and countless comets, asteroids, and meteorites in the universe.

Because there is an atmosphere on the surface of the earth that protects humanity from some suffering.

Because the distance between us and the universe is too far, and the universe is too big, we certainly can't feel it.

This is because the universe is so far away from us that we can't feel it.

In the universe, supernovae** and black hole devouring events often occur.
