Physics challenge - Prove that mass causes gravitational acceleration |
We know that photons are affected by gravitation, which proves that
energy causes gravitation.
The fact that massive bodies are affected by gravitation does not mean
that the gravitation was caused by the mass, as massive bodies also
have energy.
So I challenge the physics community to prove that mass causes
gravitation or to accept that it is only energy which causes it.

Hello,
I just joined the group, so I'm not aware of what was discussed before.
But I think I can clear a bit the last comment.
Energy is causing gravitation. But total energy is composed of
momentum AND mass. The E=mc^2 formula is only valid for particles at
rest. The complete equation is:
E^2 = m^2 c^4 + p^2 c^2
where p is the momentum (p = mass * velocity, for low velocities).
if p=0, we find E=mc^2
So both momentum and mass contributes to the total energy, that bend
the space and the observable effect is gravity.
As for a measurement of the gravity by two objects, I refer you at the
Cavendish experiment which was performed in 1798.

I have sometimes the impression that many in the fisix community think
that not mass, but math, causes gravity.
A matter of spelling.

A body in motion has kinetic energy. A body at rest has rest energy.
Mass and energy are inseparable. If mass alone causes gravity one COULD
attribute the cause to energy -- but they'd have to prove it. Can you?
I have a theory about gravity. Basically, it says that all bodies
sublimate a sub-particle particle.
These particles travel outwards in all direction at c. That means that
any two bodies will exchange particles. As they approach a body they
are drawn in with such force
that they pull the body in the direction of the incoming particles --
which means the body is pulled in the same direction as the other body.
THIS CREATES THE ILLUSION OF ACTION AT A DISTANCE.
The force drawing the sub-particles is a vorticle force created by the
spin of all particles in the absorbing body. That's why the force of
gravity is proportional to the mass.
So, in essence, gravity is the result of mass/energy.
