10 incredible facts about gravity
Residents of planet Earth perceive gravity as something taken for granted. It is known that Isaac Newton developed a theory of world wideness due to the fact that an apple fell from his head on his head. But in reality, earth gravity is much more than a fruit falling from a tree. In our review a few interesting facts about this force.
1. Toilet physics
On Earth, people want to relieve a little need as soon as their bladder fills 1/3 of its maximum volume. This happens because of the effect of gravity on each of us. That is why astronauts being on the ISS do not need to urinate until their bladder is full.
2. Unpretentious colonization
Gravity is a very important issue when colonizing other worlds. In theory, people can live on planets, the gravitational force of which differs from Earth on Earth by no more than three times. Otherwise, blood supply to the brain will be disrupted.
3. The height of the mountains
In theory, gravity determines the maximum height of the hills rising on the planet. So for the Earth (again in theory) the mountains can not exceed a height of 15 kilometers.
4. Moon physics
During the historical mission "Apollo", the astronauts who landed on the surface of the moon checked there the action of Galileo's theory of the acceleration of free fall. It turned out that objects on the moon, regardless of their mass, fall faster than on Earth. The reason for this is the absence of air and, as a result, resistance.
Many scientists consider Jupiter a failed star. The planet has a sufficiently strong gravitational field in order to gain the necessary mass of a star, but it does not have a strong enough field to begin to transform into another light.
If we take and remove Solce somewhere in one instant, then the solar system will still experience the effect of its gravitational field on itself for some time. For the Earth, in theory, this “happiness” would last about 8 minutes, after which the celestial bodies would begin to lose their orbits.
7. Mountains on the stars
If our Sun ever turn into a neutron star, then according to the calculations of scientists, the gravity on it will be so powerful that the height of the largest mountain on its surface could not exceed 5 millimeters.
8. Mournful singing of the stars
The action of the gravitational field of celestial bodies after their disappearance is not at all a dry theory. Our solar system and our home planet are constantly experiencing the gravitational field of other stars. Given the speed of field propagation in space, many of these stars have ceased to exist for a very, very long time.
9. Candles in space
If you light a candle in the absence of a gravitational field, then its fire will be round. Moreover, the color of the flame will be blue.
10. Soda Kills
Drinking carbonated drinks in the absence of gravity is definitely not worth it. Why? This is because the absence of gravity completely changes the principle of the distribution of gases in the human body. In the best case, it can provoke an attack of extreme vomiting. That is why astronauts on the ISS do not drink soda.
