Where does the gravity go?

Heat has mass? I'll be a monkey's uncle.See, this is why creos, and most other folks, believe in the supernatural: it's almost as easy to believe my dead aunt made that vase fall over last night than it is to believe that heat has mass.Especially after watching Patrick Swayze do that thing with the penny in Ghost.

Huh?? I'm not sure I understand. Does that mean 'space' doesn't get warmed by the heat/photons because it's a void and therefore there is nothing to warm? And space seems black because there is nothing in the void to reflect the light/photons?Really confused.

Is that because space itself is a void? Then why does something in space, say liquid water, freeze once exposed to space? What is conducting the heat out of the water? Where does the heat go?This message has been edited by custard, 02-28-2005 19:41 AM

Very nicely put. I actually understood it. I'll go pat myself on the back now. Seriously though, thanks for taking the tame to post such a detailed answer.
