As discovered by Albert Einstein and explained incredibly simply by Douglas Adams, there is no such thing as a truly zero-gravity field, but it is possible to simulate gravity-free environments.
Names sometimes given or definitions made in scientific studies, It can be a little misunderstood by the public. One of these is the term non-gravity environment.
Lack of gravity is actually not something that can be encountered very easily, especially when there are huge celestial bodies right below you. So what is this? zero gravity environment what we say?
First of all, the International Space Station is also in the Earth’s gravitational field.
In fact, on Earth, the gravitational force normally 9.81 m/sq. was determined as . On the ISS, this force is more or less is 9 m/sq..
So it is impossible to say that we are free from all the effects of gravity. Yet in this environment We can experience the properties of the zero-gravity environment.
Einstein was in a zero-gravity environment at the time. be in free fall He discovered that there was no difference between them. He later defined this as the “principle of equivalence” and introduced it to the literature.
So actually International Space Station All artificial satellites in orbit, even the Moon, are constantly falling to the Earth. The Earth is already falling into the Sun, and the Sun is falling into the black hole at the center of the Milky Way… But neither of them will ever fall. cannot complete the decline.
Jumping from a high enough place and missing the ground…
The Hitchhiker’s Guide to the Galaxy Douglas Adams in his series as the recipe for flying jumping high and missing the ground shows. Technically, satellites are trying to do this, but they just can’t get it right.
Because our planet is also in motion. The reason for this situation is nothing other than the fact that a very fine balance is maintained. ISP at exactly the speed at which the Earth rotates Since it moves in a way that it falls, it always stays at the same altitude.
The same principle is used for simulations of non-gravity environments on Earth. In those studies too Airplanes are in free fall from a sufficiently high altitude.
Meanwhile Despite 100 years of work We should also point out that no method has been discovered that can distinguish between gravity and free fall.
Will satellites stay in orbit forever?
Like that an endless source of energy no. Although it is technically possible to make a satellite that can stay in orbit indefinitely, such a thing is not actually possible. First of all, the vehicles we launch are constantly their speed They need to check.
There is such a thing as friction, and due to this friction, satellites are constantly they lose speed. As their horizontal speed decreases, the amount of approach to the ground increases per unit time. Our whole goal was to fall at the same speed that the Earth was receding from under us.
That’s why Including the International Space Station, all stations have micro thrust mechanisms. These mechanisms both help determine the direction of the satellite and determine its speed. to remain above 8 km/sec. provides.
It’s entirely due to gravity, or rather There is no place far from gravity, everything creates folds in the fabric of space-time; but very, very little, a trace of everything that exists in this universe is formed.
That’s why We have a universal decline/return balance. in case. And somewhere in that balance, it’s possible for people to feel like they’ve shed all their weight.
