What happens when one turns on an electromagnet? Surely the force travels from one point to another.
Or when two enormously massive objects such as neutron stars or black holes collide. Prior to the collision, their gravitational fields are different than they are afterwards, and the newly created combined effect is propagated outward into space.
Terminology that indicates no proof, but a strong belief. That's fine. But it hasn't been measured, has it?
Or when two enormously massive objects such as neutron stars or black holes collide.
A black hole collision has not been seen (as far as I know), so you are basing this statement upon models (I assume) which are inherently flawed since they are based on the developer's biases and data.
Tell me--how does a "graviton" particle that is traveling away from the source object actually attract another object towards the source object?
