gravity caused by pressure and mass

Post 1

The Cracken

Gravity is commonly thought to be produced by the presence of mass, which distorts the space-time continuum.

Perhaps gravity is not produced by the presence of mass.

Perhaps gravity is actually produced by the pressence of mass under pressure.

Why do I say this, you ask?

I say this because:
It is an attempt to account for the vanishing of energy that occurs when a mass is subjected to an increase in pressure and remains the same volume.

Doesn't the energy just transform into heat, and dissipate?

If the volume remains the same, no work is done (ie no energy transferred) no matter what the pressure...

So, in fact, I don't think there's any energy going missing.

Gandalf ( Got my own Comp Now!! Still Redundant!! )

From what I remember from the basic Physic I did, energy can neither be created or destroyed.

If the energy is transformed into heat, and the heat dissipates, ALL the heat energy is still there. It is just dissipated over an expanding volume of space.

Thats what I think, anyway!

the energy is used to keep the object the same size so it is not missing but merely being used.
