forrest gourgeon  asked the Naked Scientists:
   
If gravity is just energy and takes up no space how is it located in the core of the earth and and how dose it exist if it is impossible for it to over lap other matter yet it dose not occupy any space?

What do you think?

[Vern]

I have a speculative notion about how it works; but since it is speculative it belongs in another forum. Mainstream theory does not answer questions about why things are the way they are. The link to the speculative notion does answer those questions. []

We know from close observation that there is no gravity shadow; massive objects do not block gravity as far as we can determine.

[Mr. Scientist]

Gravity does not travel through matter. It's mediated between matter via gravitons. Essentially-simpler than that, matter is gravity.

The same way radio waves travel through matter.j

No. Matter is the presence of gravity. Gravity causes a warp of spacetime which surrounds it. Over periods of time, eventually the gravitational ''radiation'' leaves near the surface, but expecting a radiowave to move through matter, does not so in a very fast speed, even if it did actually arrive from the other end or not. Only netrino's so far can move almost undetected through matter because their speeds are short of c. Whilst gravitons have a speed of c, you must then think in terms of what General Relativity is and what it imples here. In this sense, mass gravitationally radiates, and is mediated through a field to the surface of the next mass.

Even simpler. A graviton is nothing but every fundametal particle form of mass or energy. The particle which is comprised of a pure rest energy which causes(spacetime warping). his warping is a distortion of spacetime, and it is here any planetery or particle system can loose mass through the gravitons appearing around the fields which surround the said systems.

[Mr. Scientist]

To say gravity travels through matter, knowing that Matter=Gravity, and so matter in general travels through itself. This cannot be right, but geometrically, you would get no where.
