If the earth turns twice, will day and night become six hours? What will human life be like?

If the earth's rotation speed doubles, will day and night become six hours? Let's solve it with a math problem.

The current speed of the earth:

360 degrees (the earth rotates once, 24 hours) ÷[60 (60 minutes per hour) ÷4 (the rotation angle of the earth per minute is 1/4 degrees, 4 degrees per minute) = 360 ÷ 15 (rotation angle per hour) =24 hours.

If the earth's rotation speed increases by one: 1/4×2= 1/2 (the rotation angle is twice the original).

360÷(60÷2)=360÷30= 12 (hours)

From the calculation results of the above mathematical problems, we get the answer: the earth's rotation speed doubles, and the time of the earth's day is 12 hour.

Since the apes evolved into modern civilized people, after 100 million years, they gradually adjusted the gravitational form of the earth's magnetic field and formed a set of scientific laws for human survival. If the earth's rotation (including revolution, of course) accelerates (no matter how long it accelerates), it will destroy the inherent law of human existence and cause unimaginable bad consequences for human existence. Even if people live according to the present time, when people suddenly move from East Ban Qiu to the Western Hemisphere, there will be jet lag.

If analyzed according to the conservation law of science, the gravity between planets in the universe will change, which will affect the planets themselves or the surrounding galaxies, but it is also slow. According to scientists' calculations, the time of the earth's revolution is prolonged (only a fraction of a second every year or several years), which in turn may slow down the earth's rotation, rather than accelerate it. If the earth rotates faster, it is unscientific and should be a false proposition.
