ydoaPs Posted March 7, 2006 Share Posted March 7, 2006 you must have completely missed my post. i explained it, but it is far from GR. he is only 14. if you want GR, try: http://en.wikibooks.org/wiki/General_relativity Link to comment Share on other sites More sharing options...
Anjruu Posted March 7, 2006 Share Posted March 7, 2006 Sorry. I deleted an essentially useless post. I noticed that, once again, I have failed to see that the page i was reading on was not the last page...go me... Link to comment Share on other sites More sharing options...
whap2005 Posted March 7, 2006 Share Posted March 7, 2006 I did read your post, and I agree with you. I was just pointing out that science, or more specifically GR, has yet to explain why Mass/Energy causes gravity or what its purpose is. I appologize If I wasn't clear.

Daecon Posted March 7, 2006 Share Posted March 7, 2006 I'd have said neither heat or rotation but mass. Link to comment Share on other sites More sharing options...
The Peon Posted March 9, 2006 Share Posted March 9, 2006 OK so question... I hear that they say gravity is a weak force in nature, but what if we think its weak because the matter on our planet is so undense? Like, maybe on a pulsar, since the mass is so great in such a small area, that gravity shows its true power? Am I missing something here? I guess my question is why is gravity a weak force based on what we observe as its effect on our planet? Is it due to its effect on a particle to particle basis?

ydoaPs Posted March 9, 2006 Share Posted March 9, 2006 read my post with the LaTeX. it explains it. Link to comment Share on other sites More sharing options...
herpguy Posted March 9, 2006 Share Posted March 9, 2006 (oh and LMAO at the guys who voted in this poll ) I voted in this poll... I said spin because astronauts in training spin around very fast on some sort of thing (sorry' date=' that's all I know about it). The spinning increases the G's to match those of taking off in a space shuttle. So maybe we shouldn't be laughing at all. [Gah'] Link to comment Share on other sites More sharing options...
Connor Posted March 10, 2006 Share Posted March 10, 2006 that's a sort of artificial gravity caused by momentum, though... Link to comment Share on other sites More sharing options...
ydoaPs Posted March 10, 2006 Share Posted March 10, 2006 it isn't gravity. it is an object trying to travel in a straight line, but being stopped. Link to comment Share on other sites More sharing options...
nanogrinder Posted March 10, 2006 Share Posted March 10, 2006 its an acceleration? Link to comment Share on other sites More sharing options...
ydoaPs Posted March 10, 2006 Share Posted March 10, 2006 the acceleration is towards the center of rotation. Link to comment Share on other sites More sharing options...

NeonBlack Posted March 10, 2006 Share Posted March 10, 2006 Yeah, "centrifugal force," which is the outward force cause by rotation does not exist but is actually a "pseudo-force," since the rotation frame is non-inertial. I voted in this poll too, just to see how many people had actually voted. Link to comment Share on other sites More sharing options...
swansont Posted March 10, 2006 Share Posted March 10, 2006 Yeah' date=' "centrifugal force," which is the outward force cause by rotation does not exist but is actually a "pseudo-force," since the rotation frame is non-inertial.[/quote'] But the actual acceleration is centripetal, which, as yourdad notes, is toward the center of rotation.
