Venus's slow rotation will also cause a series of problems. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The first is the disappearance of the Martian magnetic field. Because the rotation of Venus is too slow, even if Venus has a "thermocore" like the Earth, it cannot make this "thermonucleus" produce a "generator effect" because of its own slow rotation, so the magnetic field strength of Mars is only 1/100,000 of the Earth's magnetic field strength.

Although it is difficult for the solar wind to strip the Venus atmosphere from Venus because the concentration of Venus's atmosphere is large enough, once the concentration of Venus's atmosphere is reduced in the future, if there is still no protection of Venus's magnetic field, then Venus's atmosphere will end up in the same ending as the Martian atmosphere, and a large amount of gas will be stripped out by the solar wind every day.

And without the protection of the magnetic field, then all kinds of harmful rays from the universe will penetrate the atmosphere of Venus without any scruples, causing huge damage to the earthlings who have migrated to it.

Therefore, in order for Venus to become a planet suitable for human habitation and self-protection, it must first have its own planetary magnetic field. Only by putting on a layer of magnetic field "protective clothing" can you confidently and boldly immigrate to Venus.

At the same time, because the rotation is too slow, Venus has a day longer than a year. Although it is not a spoof to let earthlings play "chasing the sun" on Venus, this kind of diurnal change of time span distance is definitely not suitable for earthlings to survive on it.

And because the rotation is too slow and the angle of Venus is too small, there are no seasons on Venus, which is absolutely unsuitable for the immigrants of the earth.

Therefore, in addition to solving the atmosphere of Venus and the numerous volcanoes on Venus, how to solve the problem of Venus's slow rotation is also a huge problem in front of Tang Feng.

Among the eight planets in the solar system, there are many "lying horizontally" rotating like Neptune, but Neptune is too far away from the Earth, and the conditions there are even worse than those of Venus, so whether Neptune is willing to "lie sideways" or "stand up straight" has nothing to do with Tang Feng.

But Venus is different, the distance from the sun is moderate, as long as the gas content of the atmosphere of Venus is controlled, then Venus is the second Earth.

But if this problem of slow rotation can't be solved, Venus will be a complete joke.

In fact, Venus's rotation is too slow and it is also a problem of reverse rotation, which scientists on Earth have not figured out until now.

Venus's rotation direction is from east to west, so the sunrise from Venus is west and east set. Venus is also the only planet in the solar system that rotates from east to west.

The entire solar system, including the sun itself, rotates in a counterclockwise (right-handed) direction, which is called west-to-east, and even the orbits of all the planets in the entire solar system rotate from west to east.

If you can stand at the north pole of the solar system and look out over the entire solar system, then you will find that in the relatively neat orbit and rotation of the solar system, there are two planets that stand out in particular: Uranus in the far periphery, and Venus next to the sun.

Uranus rotates "lying", but if you look at it from the north pole of Uranus, Uranus actually rotates counterclockwise (right-handed), so in general, although Uranus rotates in a sleeping position, it is not separated from the big family.

But Venus is a little rebellious, this guy not only rotates in reverse, but also rotates very slowly, which is particularly different in the movement of the major stars in the neat solar system.

Why the rotation of Venus is reversed, and why the rotation of Venus is getting slower and slower, although scientists on Earth do not have a unified conclusion on this, they can roughly say why.

There is a more mainstream theory called the "Earth Expansion Theory", which explains the reversal of Venus and several other moons more clearly.

At the heart of this theory is that when the solar system was just forming, the primordial sun exploded due to nuclear fusion inside, sending out many molten fireballs. Due to the different magnitude and direction of the force, the rotation direction, the inclination of the axis of rotation, and the distance from the sun of these fireballs are also different, which causes the rotation of Venus to be in the opposite direction of its revolution, the rotation direction of Triton around Neptune is opposite to the direction of Neptune's rotation, and Enceladus is also a retrograde moon.

Of course, this "rebellious" situation does not explain the slow rotation of Venus, but one theory for the slow rotation of Venus is that Venus is closer to the Sun and is attracted by the tidal gravity of the Sun, as if the Earth's tidal gravity locks on the Moon, resulting in the Moon always facing only one side of the Earth. Although Venus is not yet completely locked by the tidal gravity of the Sun, the huge effect of this tidal gravity also makes the rotation of Venus slower and slower.

Of course, there is another theory that also comes from the "Earth Fragmentation Theory". This argument is not as powerful as the tidal gravitational theory of the sun, but it is extraordinarily ingenious.

According to the "Earth Fragmentation Theory", in order to understand this, we must first understand how the rotation of the earth came about. The "Earth Expansion Theory" believes that the solar system is a rotating body, because the outer half-longitude of the earth is greater than the half-longitude of the inner side of the earth, and because the earth is relatively uniform, the mass of the inner and outer sides is equal, and then assuming that the solar system is a steel body, the angular velocity of the inner and outer sides of the earth is equal, so according to the angular momentum formula l=mr2w, it can be seen that the angular momentum of the outer side of the earth is greater than the angular momentum of the inner side of the earth. Since the earth is in a suspended state, the angular velocity of the outer side of the earth is greater than the angular velocity of the inner side of the earth, so the rotation from west to east is the same as the direction of the earth's revolution.

According to this reason, Venus with an outer radius greater than its inner radius should also rotate in the same direction as its revolution from west to east, but why does Venus rotate in the opposite direction? The "Earth Splitting Theory" also provides a very scientific explanation for this.

According to the theory that the eight planets of the solar system and the asteroid belt are formed by the "fireballs" thrown by the newly formed sun, these fireballs thrown by the sun contain huge amounts of solar matter, and the same is true of Venus. It's just that because Venus is closer to the sun, it happens that because of the sun's gravity, all the heavy elements in this fireball that has not yet solidified are gathered in the part facing the sun, which causes the situation of Venus "one head is light and one head is heavy", so the angular momentum on the inside of Venus is greater than the angular momentum on the outside of Venus, and Venus rotates (reverses) from east to west.

In fact, this statement can be confirmed by a very simple experiment.

Fill a large laundry tub with water and stir the water counterclockwise along the edge of the basin with the palms of your hands. When the water is turning, place the thermos with the plastic lid facing up on the water against the rim of the basin. At this time, it was found that while the plastic cover rotated counterclockwise (revolution) with the water, it also rotated counterclockwise (autorevolution) itself. This is an irrefutable experiment in which the rotation of the earth produces its rotation. Because the Earth's revolution is from west to east, the Earth's rotation is from west to east (counterclockwise).

The same basin, the same counterclockwise stirring of water, at this time you put a slightly heavier thing into the plastic cap towards the side of the basin center, and then put the bottle cap into the water, then you will find that although the bottle cap is still rotating counterclockwise with the water, it is magically rotating clockwise. This is because the weight on the inside of the cap is greater than the weight on the outside.

This is the irrefutable experiment of the reverse rotation of Venus.

However, whether it is due to the tidal gravitational lock-in of the Sun or the reverse rotation caused by the uneven distribution of heavy elements in Venus, it is not a simple matter to solve this matter. Even if there is a star core, it will not be possible to solve this matter in a few years.

The sun's tidal gravitational locking is a bit of a point, but the key is that if the heavy elements on the inner side of Venus are evenly dispersed to other regions of Venus, it will take at least several decades of water milling to slowly grind.

But fortunately, Venus immigration is not something that can be achieved in recent decades, so grind slowly! (To be continued.) )
