Graviton collisions

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>[Rudolf]: When two (or more) gravitons (the Le Sage or MM type) collide, is there some energy that is 'lost'?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

The answer is the same as for air molecules. The mutual collisions are almost perfectly elastic (although nothing in nature is "perfect"). But when the fine details can be measured, probably some tiny "graviton fragments" go flying off and are lost to the main sea of gravitons. For practical purposes, there are no losses.

No, gravitons are as small compared to quantum entities as the latter are small compared to us. Besides, the best evidence is that the microwave radiation is just the natural limiting temperature of anything in space, given that it is bathed in the radiation of distant starlight. (Eddington showed that calculation actually works.) -|Tom|-

Thanks, there might be another way of looking at it. Since the space between the stars and galaxies are not 100% empty - dust, gasses and some free floating molecules, graviton collisions with these will raise their temperature somewhat. Since we cannot always (mostly) see these things directly our detectors can only pick up the 'universal' radiation radiated into all direction.

Has the 'heating' effect because graviton collision been proven in any way yet?

Gravitons have not been discovered yet. They are theoretical. But the Moon and five planets do have excess heat flows. -|Tom|-

Out of curiosity, which five planets are we talking about and how mush excess heat per planet? Can there be any other explanation for this effect?

The heat flow tables appear in the book <i>Pushing Gravity</i>, together with possible alternative explanations. These heat flows have been measured for the four gas giants, Earth, and Moon. -|Tom|-

Not having read the book, I'm at a disadvantage. Shouldn't all large bodies exhibit the excess heat flow (Mars, Venus, large ateroids, etc.)? How is it measured?
