10 amazing facts about gravity, which are not told in school
• 10 incredible facts about gravity, which are not told in school
The inhabitants of the planet Earth perceive the force of gravity, as something for granted. It is known that Sir Isaac Newton developed the theory of gravity because his head apple fell from the tree. But in fact, the Earth's gravity - it is something far greater than a fruit fallen from the tree. In our review, some interesting facts about this force.
1. Dressing physics
On Earth, people want to celebrate small need, as soon as their bladder fills up to 1 \ 3 of its maximum volume. This occurs due to the action of gravity on each of us. That's why the astronauts staying on the ISS have no need to urinate up to the very long as their bladder is not full.
2. unpretentious colonization
Gravity is a very important issue in the colonization of other worlds. In theory, people can live on the planets, the gravitational force which is different from the Earth no more than three times. Otherwise, the blood supply will be disrupted in the brain.
3. The mountains
In theory, gravity determines the maximum height on the planet formed hills. So for the Earth (again in theory) the mountain can not exceed a height of 15 kilometers.
4. Moon physics
During a historic mission "Apollo", landed on the lunar surface, astronauts tested the effect of Galileo's theory there is the acceleration of free fall. It turned out that on the moon objects regardless of their weight fall faster than on Earth. The reason for this lies in the absence of air, and as a consequence - resistance.
Many scientists believe that Jupiter is a failed star. The planet has a strong enough gravitational field in order to gain the necessary mass of the star, however, is not a strong enough field to begin to be transformed into another light.
If you take and remove soltse somewhere for a moment, the solar system will be for some time to suffer the effects of its gravitational field. For the Earth, in theory, is "happiness" would have lasted about 8 minutes, after which the heavenly bodies would have started to lose their orbits.
7. Mount the stars
If our sun someday turn into a neutron star, according to the calculations of scientists, gravity it will be so powerful that the height of the biggest mountains on its surface could not exceed 5 millimeters.
8. mournful singing star
The action of the gravitational field of celestial bodies after their disappearance is not dry theory. Our solar system and our home planet is constantly subject to the action of the gravitational fields of other stars. Given the speed of propagation of the field in space, many of these stars have already ceased to exist very long time.
9. Candles in space
If you light a candle in the absence of a gravitational field, then it will fire a round. Moreover, the flame will be blue.
10. Soda kills
Drinking carbonated beverages, in the absence of gravity definitely just not worth it. Why? This is because the absence of gravity reverses the principle of distribution of gas in the human body. At best, it can provoke an attack of vomiting. This is why drinking soda is not the astronauts on the ISS.
