[xelasnave]

Intersting idea, but I'm not sure that explains anything gravity doesn't. Many things in physics can be expressed equally as either a positive force or a negative opposing force. I think I've actually heard this concept of gravity before. Mathematically, I think the two concepts are identical.

That's pretty much exactly what the 'standard' theory of gravity says too. If you built a heat resistant hollow sphere and put it at the center of the earth, you could float around inside it and feel 'weightless'. Provided that you didn't get too far away from the center point, since then you wouldn't be in equilibrium. Under standard theory, you would hover there because you'd be pulled by the rest of the mass of the earth equally. Under xelasnave's theory, you would float there because the pressure pushing on you would be equally balanced as well. You can't block ALL the pressure pushing on you (black hole?) since then all the electrons and atoms in your body would fly apart.
Alex….. well lets go the opposite way past the great walls of galaxies to where we find the voids. Consider all that meets you there I suggest that on this approach to say we are without gravity and weightless is not the way to look at it weight is irrelevant it is a Earthbound human concept. In space if we are floating I suggest it is the gravity rain from all directions that provives this phenomenon.

One thing though that this brings up is something that scientists are still arguing about and is one of my favorite theoretical subjects.

Xelasnave's theory advocates that the 'speed' of gravity is infinite and felt everywhere at once.
Alex…. no
I I think we are limited to the speed of light, as gravity rain must be part of the electromagnetic system and as such should travell at the speec of c. But it is felt everywhere but fluctuations in pressure are presumably bound to C.
This is basically the Newtonian Physics view of things. Einstein physics says that gravity propogates at the speed of light. In the newtonian view, if the sun disappeared now, the earth would immediately go flying off into space, even though the sun would appear to stay in the sky. The Einstein view says that we'd happily move along for another 8 minutes or so until we SAW the sun disappear and THEN go flying.
I agree with the great man and saty that the gravity message from the Sun is in effect 8 odd minutes "late"

Conceptually, accepting the Newtonian way makes more sense... but many tests and LOTS of math seem to indicate that Einstein's explaination is what actually happens. (IE: frame dragging, etc) People are still arguing about it, and basically there's a lot of math in general relativity that attempts to reconcile this effect... I think a lot of mathematicians don't like it because it seems too complex, but nobody has been able to disprove it yet. There IS an explaination that fits the 'gravity obeys the speed of light' thing... but I'm not smart enough to understand the equations
alex....I see it this way gravity travells at c gravity rain explains the force causing space time to bend and as such it does not seem to conflict with the math.
I am sorry this reply is a little out of order.. had to do it on the run so I was not able to put as much into it as I should please forgive my off the top of my head approach...but in the interest of moving on I have let it go this way...and now doubt being so hasty I will have made errors that you can get onto.
Thanks I have not had so much fun since I read the dictionary backwards.
