Why do we have the Hubble limit?
Why the numbers of quanta fall off with the square of the distance.
Scientists agree that Einstein's principle of equivalence is correct.
why gravity acts like acceleration
The speed of gravity
amount of mass increase
is equivalent to the mass increase
Relative mass is increased near a ponderable object
by accelerating something
Einstein was correct with his principle of equivalence.
