What exactly is mavity? :o Obviously we know what mavity does, and all explanations say mavity is a force that attracts objects together, which we also know. But I'm not sure what the force is that makes up mavity. Is it electro magnetism?
 
^That's my understanding of it.

But people who study it and physics don't really understand it that well. In every way it's broken down it doesn't fit with others of its type ((a function of mass, a force, an energy* etc.).

* I know what I mean by that. However bar saying 'thing'...
 
mavity will pull all mass together eventually, whilst the universe outside of it expands infinitely and then you have an infinitely small amount of infinite mass in an infinite field that is the universe.

Then it folds into itself and **** happens.


I just made all of that up.

I just realised I never answered the question, I just thought it was the bonds between atoms pulling things together? But I guess they can't be that strong to glue us to the earth. And then if that were the case, what is the actual force that makes the atoms come together. :O

We don't know, which is one of the major reasons for spending billions on the Large Hadron Collider!

But it is basically a warping of spacetime caused by the mass of an object.

I read this article about space time. Quite interesting, but still no wiser. For one thing, I'm finding it hard to imagine how space (nothingness) can be warped, unless we're talking about dark matter or something, and although the article attempts to explain mavity, I don't fully understand the concept of the time aspect in all this, and how that is part of mavity.

I'm sure you're right, but it doesn't clarify anything for me.:p

Stuff moves in straight lines. Stuff(with mass) warps space-time. Big enough stuff warps space-time to the extent that stuff traveling in straight lines gets caught in the warped space-time and orbits the big stuff, giving the illusion of an active force with the big stuff pulling on the small stuff.

Note how the path of the smaller rock would be affected if it were rolling on a pool table which was the same shape as the 2D plane of space-time here:

And to picture it in 3 dimensions (left image):

Clicky - Image too big to embeddddd :(
