Are planets really moving in a vaccum and are suspended on nothing?

Answer 1

Nothing can be suspended on nothing.

The planets, for example are not suspended. They are held in their orbits, just as surely as you are held to the surface of the Earth, by gravity.

The only difference is that they move fast enough, and are far enough away from the sun, that they do not fall. Actually, the planets are constantly falling, but the speed of their orbits exactly balances out the rate of their fall.

This is how the moon stays in the sky, and how sattelites orbit the earth.

Answer 2

Yes, planets, stars, the Earth, our Sun and Moon, and everything in the Universe exists in the vacuum of space. Life on Earth however lives within a thin biosphere consisting of Earth's atmosphere, liquid ocean, and thin continental crust.

The planets are not suspended in vacuum in the way things can be suspended in air or in water. On Earth there is an uniform gravitational field that keeps everything on the ground. Therefore you can suspend object in the air or in water if there is sufficient force to counteract Earth's gravity. In space, you would be in freefall, which means you would be orbiting around the closest massive object (like a planet or moon, or the Sun).

The motions of the planets, and stars (including our Sun) are entirely due to gravity (i.e. the Earth orbits about the Sun, the Sun orbits about the galactic core of the Milky Way). However, our home galaxy, the Milky Way, is moving away from most other galaxies in the Universe due to the Big Bang expansion.

Answer 3

The invisible frame work large masses such as planets and galaxies “hang” on to are termed gravitational fields. These fields influence objects within these regions . The influence they create are detectable as gravitational forces. These forces change the momentum of an object. In all the observable planets and galaxies their particular movements are the resulting balance form the laws of momentum and the laws of gravity. Newton was able to show that the force that say, causes an apple to fall to the ground, is exactly the force which influences the moon to orbit the earth. Einstein’s general theory of relativity explained this phenomena in terms of a local space time perturbation caused by mass, itself yielding an even more precise calculation of this gravitational force. How something here affects something there without any detectable rod or scaffolding is answered by the yet to be discovered graviton, mediator of the gravitational force, something akin to photons, the quanta which mediates the electromagnetic forces. This graviton is something like a billardball which goes from here to there “interacting” an exchanging
this force.

Answer 4

Planets are suspended on a sheet of space and time which when disturbed by a weight that exceeds M unit occupies space from the space most leaving time alone for which you have to work on the same formula which is if E= MC(2)= S+T ( ? )
? is a term given to Dark Matter.

Answer 5

Inertia keeps the planets moving. The vacuum makes the friction zero. Gravity keeps them in orbit. No magic, just plain science.

Answer 6

Yes. The planets are hanging on to our sun. The suns gravity keep them in orbits. The orbits make sure they dont fall on to the sun.

Answer 7

no and no.

Although there isn't as much atmosphere in space as there is on planets with gravity there is gases out there.

Gravity versus momentum and centrifugal force keep the planets in place. you can't see it, you can't feel it. but it's there. Just like God.

Answer 8

if you look really close you can see the fishing line holding the planets up.

Answer 9

keep on reading past that chapter.

Please, put down the bong and get a book on basic astronomy.
