What if there is no gravity?

[killer-curry]

I think without gravity generally we are going to float away to the space, and things go crazy, any ideas?

Everything would fall apart. On the subatomic level. Quarks wouldn't stick together anymore so there would be no matter nor antimatter and everything would just desintegrate into the smallest particles something can be reduced to.

Unless you mean what if there were no gravity on Earth anymore as in the Earth stopped pulling anything. Then we'd float away, the atmosphere would fly into space, water would evaporate and you'd end up in a vacuum where you'll be conscious while feeling your saliva boil in your mouth and every inch on your body hurting like hell before you pass out and die from oxygen deprivation. Unless you tried to hold your breath, then your lungs will rupture and you'll die faster (and more painfully).

I think Life is not possible as in Universe everything is holp up by gravity so if there will be no gravity there wouldn't be galaxies, or stars, or planets.
Moreover, as far as i know, most dangerous fate on earth will become in the absence of gravity is that breathable air would probably get spring into the vacuum of the space and at last, all living beings will die.

If gravity just stopped existing, besides us floating out into space, the Earth wouldn't orbit the Sun and the Sun wouldn't stay inside the Milky Way. They would speed through the universe without stopping unless they collided with something else.

If it didn't exist at all, nothing in the universe would either. The Earth wouldn't have formed, the Sun wouldn't have formed and so on.

Quarks aren't held together by gravity though. The gravitational forces between particles of such low mass is practically non existent and, as far as I know, cannot in anyway hold them together against the much, much stronger electrostatic repulsive forces between two up quarks or down quarks.

Even though gravity is the weakest force to exist in the universe, the universe cannot exist without it.

As far as I know, gravitons do play a big role in the string theory. If the string theory is right and the smallest particles of pretty much everything are tiny one dimensional strings, the absence of gravitons would make them disappear/fall apart and that would result in everything in the universe being destroyed/

But strings are only one dimensional vibrations and as far as I know, Gravitons themselves are a specific vibrational state of these strings, not the other way around. I.e. gravitons don't make up strings, strings make up gravitons.

Oh well, my bad then, sorry about that.

Anyways, taking away one of the four fundamental forces of the universe still won't do anything good an it'll end up severely messed up.

Would be pretty cool, end of the world haha.
