What will happen if ther was no gravity?

Answer 1

If there was no gravity, the planets wouldn't circle in some sort of line or order around the Sun. It is the Sun's gravity that pulls the planets all in one line. Also, if there was no gravity on Earth, we wouldn't be here now, we would be all over the place, because of the resisting force, which would pull us up. When we jump, we get pulled down, thanks to gravity. Therefore, it would like be living in space, and the planets would be like us - floating all over the place!

Answer 2

This is a fantastic answer that most don't commonly think about. Let's assume that everything about the earth that we know today remained the same, except its gravitational pull. And let's say that earth suddenly LOST its gravitational pull. This means that you have no weight. So, let's say that you decided to go for a dive in your swimming pool and you jump off the diving board. Instead of falling into the water for a fun splash, you'd go flying into the sky and you would never come back. Scary thought, isn't it? In fact, it gets much, much worse. Not only would you go flying off to Neverland, but the moon would likely fling out of its orbit around our planet. This would probably pull a huge tidal wave up and over the world. And since water binds to itself, the world ocean would probably follow, blocking out the sun, and either causing us to boil or freeze (I don't know). But that's a very unlikely scenario. Now let's assume that earth originally formed without any gravity and somehow life was still possible. We'd be much different as a species. In fact, we would understand physics from a MUCH different perspective because part of our lives requires that we have gravity. Now just for a little fun, have you seen the movie "WALL-E"? I want you to go and watch that (It'll be fun and you'll learn a little something). In this movie, the effects of low gravity on the human body are partially explained (Just have to pay attention). If you have already seen it, I'll explain it further. Gravity not only keeps us on the ground where we're nice and safe, but it keeps us from growing too stretched. Now imagine without gravity. Over time, we'd experience muscle deterioration and other physical ailments. BTW, did you know that a pioneer in the area of physics and gravity was Isaac newton? ~Apple Juice
If there were no gravity, everything would be floating, because gravity is everywhere.

Answer 3

If gravity went away for ever, we would fall off earth, float in space and die because there is no air in space. We need gravity so we may live and stay on Earth and breathe air, haver water to drink. Thats what would happen if we didnt have gravity.

Also. The sun and other stars would cease to keep going and would most likely break apart. The planets would start to break up as well since no gravity is holding them together.

Answer 4

There is ! And all the motion of everything you see in space is the result.

Because of gravity, there is a force attracting every object everywhere toward every other object everywhere. The closer together two objects are, the stronger the force is between them. Also, the more mass they have, the stronger the force is that's trying to pull them together.

This is what keeps air, water, and you on the earth. It's what made the earth round, keeps the sun all together in one ball, keeps the earth revolving around the sun and the moon revolving around the earth. It's what keeps the TV satellite revolving around the earth, and it's the reason it took so long for the US and USSR to succeed in tossing anything upward hard enough to make it leave the earth.

Answer 5

The people on earth, known commonly as humans, will perish in the rivers of the ancient stream. Saskia will survive. It's all good. What would happen to the things on Earth depends on how they are attached. As you know, the Earth is rotating at quite a speed. Now if you spin something around your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. If the circle is very big, then at first the straight line is almost the same as the circle -- however, after a short amount of time, the two paths will be very different, since the circle bends around but the straight line does not. "Switching off" gravity is analogous to letting go of the string. Things not attached to the Earth in any other way would fly off into space in a straight line that would take them away from the surface of the Earth. In buildings, people would start floating gently upwards until they bumped into the ceiling. Outdoors, however things would start floating away from the Earth gently but eventually go much faster, as their straight lines took them farther and farther away from the circular path that the spinning Earth takes. The Earth's atmosphere itself would also float off into space, for the same reason! Some things are rooted into the Earth. They would not fly off because they are being held down. In fact, the force you would need to hold on and keep yourself from flying away from the Earth is very weak, only about 0.3% as strong as the force of gravity (and even weaker away from the equator). However, things which are holding on to the Earth would eventually have problems too -- the Earth itself would most likely break apart into chunks and float off into space, since it is only held together by gravity also.

Answer 6

Without gravity, all objects would float freely in space. There would be no weight, no falling, and all celestial bodies would drift apart. The absence of gravity would have a profound impact on the structure and behavior of the universe as we know it.

Answer 7

We'd all die!

If there was no gravity, the universe would not have come about.

Answer 8

If there were no gravity, the solar system would not exist.
