why is gravity weakest force of all forces???????

Answer 1

if there are several forces of different strengths, one of the, gotta be the weakest.
Why not gravitiy?

Answer 2

Obviously those of you contesting that gravity is not the weakest force know nothing of physics. It has been known for decades that gravity is the weakest force. The energy generated from a cement truck falling off a cliff (due to gravity) is easily counteracted but the weak nuclear force of repulsion when the truck hits the ground and stops. All of the energy built up by the truck during fall is opposed equally, simply by the earth being there to stop it. Yet one atom in that truck could be split releasing the strong nuclear force and creating an explosion with the force of several megatons. The electromagnetic force is no wimp either. The gamma (light wave) radiation given off by that explosion will burn everything in the immediate vicinity instantly.

So to address your very valid question (despite the disbelief of some other users), I would suggest doing a Google search on brane-theory (short for membrane) or M-theory. Scientist know that gravity is by far the weakest force, but they can only speculate as to why.

Answer 3

I don't know why, but It is the weakest.
Lets look at everyday life - weak and strong force are the forces holding the nuclei together. They are VERY strong, but have only for a short range. bet you never tore up a nuclei. They do that only with massive and strong instruments.

Electromagnetic forces are holding the atoms together. it is breakable with chemical reaction and so forth, but you need some energy to do that. it also holds solid matter together, but only as a side effect, and yet - you can break some of it, with force, but rocks and metals, held together by EM forces are hard to break.

What about gravity? you lift you body above earth any time of the day!

There you have a bit of a laim explanatin, but still very intuitive!

The reason why many people here doubt this fact is that gravity, unlike other forces, has only one direction - it only attracts. this fact give it some dominance over the other power in the universe.

Answer 4

It's hard to say. But one could say that if gravity had a strength other than what is has in our universe, we might not even be here to observe it, because the universe as we know it depends on gravity having the strength that it does have. And even though it has the weakest relative strength, only gravity and electromagnetism operate over long distances, and only mass is an innate property of matter. So gravity is, in a sense, the most universal of all fundamental interactions.

Answer 5

Who says it is the weakest force? Any object that has mass exerts a 'pull' - that is, has gravity. The more mass the object has, the more 'pull' it exerts - so, eg, a small planet with have weaker gravity than a larger one. So it depends on the mass of the object you are considering.

Answer 6

Is it?? How about black holes? They're no wimps!! Their gravity is so strong, not even light can escape. Also gravity has an incredibly far reaching influence. Everything in the universe is exerting a gravitational influence on everything else.

Edit: But then again, I don't actually know anything about physics, so you should probably gravitate towards the answer given by babblefish, who seems to know what he's talking about!

Answer 7

Because creatures like us could not exist if gravity were stronger... this is the anthropomorphic principle... change the conditions and we wouldn't be observing this.

If you want a good demonstration of how weak gravity is... your body is attracted to this large mass below your feet (Earth), but a bunch of electrons that don't want to be squished closer together keep you on the surface.

Answer 8

I don't understand the "why." Kind of like asking why is milk milk?"

Answer 9

is it???????? i thought that is one of the most powerful forces...i mean that holds the whole solar system together...

Answer 10

and yet the greatest, and still not understood
