How Does Gravity Work?

Gravity is definitely one of the major phenomenons we take for granted. We're aware that everything, not only on Earth but in the Universe as well, is affected by it. Yet, scientists can't seem to find a definite answer as to why it actually exists and how it works.

Here's what I found on Cracked while looking for some possible answers on the subject:

Quote:Come on, it's gravity. Is there any concept in the universe quite so basic? You throw shit up, it comes down again. Despite his textbook reputation, Newton didn't discover gravity. It was discovered by the first fish ancestor who crawled onto land and found it had lost the ability to swim upward. What's to understand?

Turns out there are four basic forces that hold the universe together, and out of these four, gravity is the only one that doesn't make any sense. Specifically, how it can be so incredibly weak and incredibly strong at the same time. Gravity holds the entire universe together, and no matter how far out you travel, it never completely disappears. And yet, it is the weakest force in existence. To illustrate, you know when you bring two magnets near each other and they snap together? That force is actually 10^36 times stronger than gravity. Yeah, the technical term for that is "a big-ass order of magnitude" stronger.

To add to the confusion, because all these other forces are controlled by their own particles, it stands to reason that gravity should have its own particles, too. But this hypothetical critter -- the graviton -- is basically the only one we haven't found yet, unlike the particles that mediate a lot of the other important forces in nature, which have been altogether more cooperative.

But the mother of all baffling gravity mysteries is that, once you get down to the level of atoms and molecules and even smaller stuff, gravity just plain stops working. In fact, gravity is one of the biggest reasons why quantum physicists and real-world physicists have nothing to say to each other. We know more about what's inside an atom than we do about why a ball comes back down when we throw it in the air. For all science knows, it's because of ghosts.

Thoughts?

Gravitons. Little circle thingies. At least according to "Through the Wormhole".

we created via a theory whats inside an atom as a descriptor.
we cant say conclusively on either end~ we have knowledge about constructed theories describing the various forces we have decided to define. is it a particle or is it a wave is it a magnetic or electrical force oh its just an electromagneticparticlewave
That is all we have.

Go ask your local physicist.

Funny you should say that... Cause I did. Not just one, but three. Each had somewhat different explanations which I'm not going to elaborate after a lazy and arrogant line like yours. Wink

How does gravity work? Threw releasing a high density of power full waves of energy as magma spirals and circles around each other or a black hole.

Gravity always seemed like a plot device to me. Without it, interactions between particles would require pure chance, and even the mathematics behind that slim chance isn't worth thinking about.

Stellen sich vor, dass es keinen Heaven gibt, es ist einfach wenn Sie versuchen.

1. What does the fact that gravity is weak have to do with anything?
2. Maybe the "particles" or more accurately the carriers of interaction for gravity are larger. < Short reply, extrapolate it.

I've gone out of touch
