Names sometimes given or definitions made in scientific studies, The audience may misunderstand it a little. One of these is the term non-gravity environment.

Lack of gravity is actually not something you encounter 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 Earth’s gravitational field.

In fact, gravity on Earth is normal 9.81 m/square second was determined as. This force is more or less present on the ISS is 9 m/second squared.

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 gravitational environment.

Einstein was in an environment without gravity at the time. be in free fall He found that there was no difference between them. He later defined this as the “equivalence principle” and introduced it into the literature.

So actually International Space Station All artificial satellites in orbit, even the moon, are constantly falling to 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 will ever fall. cannot complete the descent.

Jumping from a high enough place and missing the ground…

The hitchhiker’s guide to the Milky Way Douglas Adams in his series as a recipe for flies jump high and miss the ground shows. Technically, satellites try to do this, but they just can’t do it well.

Because our planet is also moving. The reason for this situation is nothing other than the fact that a very fine balance is maintained. IS P at exactly the speed at which the Earth rotates Because it moves in such a way that it falls, it always remains at the same height.

The same principle is used for simulations of non-gravitational environments on Earth. Also in those studies Airplanes are in free fall from a sufficiently high altitude.

In the meantime 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. While it is technically possible to create a satellite that can remain in orbit indefinitely, such a thing is not actually possible. First of all, the vehicles we launch are constant their speed They have to check it.

There is such a thing as friction, and as a result of this friction, satellites are constantly present they lose speed. As their horizontal speed decreases, the rate of approach to the ground per unit time increases. Our whole goal was to fall at the same speed that the Earth was retreating from beneath us.

Therefore Including the International Space StationAll stations have micro-thrust mechanisms. These mechanisms help determine the satellite’s direction as well as its speed. to remain above 8 km/sec. offers.

Completely from gravity, or better said There is no place far from gravityeverything creates folds in the fabric of space-time; but very, very little, a trace is formed of everything that exists in this universe.

Therefore We have a universal balance between decline and return. in case of. And somewhere in that balance, it’s possible that people feel like they’ve lost all their weight.
