There are many mysteries in the universe, and there are many mysteries that we can't solve. What are the details?

There are many mysteries in the universe, and there are many mysteries that we can't solve. What are the details? There are ten mysteries in the universe.

1. The universe is accelerating.

1920, scientists found that the universe is expanding, which may have started with the big bang120-1500 million years ago.

But we can't know whether this expansion in the universe will last forever, or whether the sudden reversal of gravity will shrink the universe into a ball. New discoveries have made this problem more serious, and the universe is still expanding at an accelerated rate.

2. Invisible virtual particles

There are many things in our universe that you can't see, among which virtual particles are the most magical. Virtual particle is a kind of particle that cannot be directly detected in quantum mechanics, but it has measurable effect.

The energy in the universe can fluctuate between fixed total values in a short time. The greater the fluctuation, the shorter the time. During this period, the particles produced by energy fluctuation are called virtual particles. If we can shoot empty space, then virtual particles may also appear.

3. Lunar magnetic field

On the moon, scientists found that only a part of the moon's crust seems to have a magnetic field, which has puzzled scientists for decades. But some scientists now think they have found the answer.

Scientists use computer models to analyze the lunar crust. They think that the magnetism of the earth's crust is probably 4.5 billion years ago, an asteroid with a diameter of about 200 kilometers hit the south pole of the moon, leaving some magnetic materials.

4. Dark matter

70% of the energy in the universe is dark energy, and scientists have been observing the function and role of dark energy. The matter in the universe is composed of dark matter, accounting for 25%.

Our naked eyes and telescopes can't see dark matter, and the gravitational effect of dark matter only moves in clusters and individuals. Scientists have been studying dark matter, but so far they have found nothing.

5. asteroid companion

Mathematical calculation shows that it is impossible for an asteroid to have a satellite in orbit, because the gravitational field of the asteroid is irregular and uneven, and it is difficult for the satellite to stay in orbit.

But in an impossible system, an asteroid with a distance of 145 km is surrounded by a satellite one tenth the size, and it will circle once every four days, only 500 miles apart. Scientists cannot understand this phenomenon.

6. Planetary devouring

There are some close celestial bodies in the universe, and they are all rotating around each other. And big stars always swallow small stars.

The big star slowly sucks the outer material of the small star into its own body, increasing its mass and volume, so that the small star will eventually become a star core with nothing.

Scientists on the two planes of the star will gradually merge into a whole because of the action of universal gravitation and move towards each other under certain laws.

7. Electrostatic levitation

Apollo astronauts found strange light on the horizon of the moon, which is thought to have happened in the earth's atmosphere. But there is no atmosphere on the moon, which makes scientists puzzled.

Later, scientists found that this light was caused by the reflection of sunlight by particles floating on the surface of the moon. Sunlight charges the particles on the surface of the moon and then suspends them, which may be electrostatic suspension. But it is very strange that these particles should reach the earth.

8. High energy cosmic rays

There will always be some high-energy cosmic rays in the earth's atmosphere, and no one knows where such rays come from. Scientists think it comes from the explosion of galaxies or supernovae. Moreover, the energy of this ray is much stronger than that of previously discovered particles.

9. Neutron stars

A neutron star is a very strange shape. Its mass is 1.4 times that of the sun, but its diameter is only 1 1-20km. It is formed by the inward explosion of a large star, which produces a very dense celestial body and then continuously squeezes electrons into protons.

Neutron stars will devour the surrounding stars, absorb the gas and dust of nearby planets through strong gravity, and then throw them back into the universe through radiation and rotation, resulting in a star wind with a speed of 7.2 million kilometers.

10. Brown dwarf weirdo

Brown dwarf is an embarrassing star in the universe. It can't be counted as a planet or a star, so it is unique. Sometimes it is cold and dark, walking alone in the universe, and some around big stars, forming a binary system. And the number of brown dwarfs is not less than that of stars.
