Is gravity (according to Einstein) the effect from a distortion in the space-time fabric or the actual curvature of space-time?

First, it’s notable: You have to realize Einstein’s theory is a model of gravitational phenomenon per our observational affirmations. In … More

Do photons have mass if they are bent by gravity?

No. It’s a massless force carrier of matter, via the electric force (or the electro-magnetic force to be broader). It’s … More

Photons are massless and so do not influence the gravitational field. They do propagate through space-time, which is influenced by … More

It’s possible gravity is an interaction between massive particles with force carriers exchanging in an unseen dimension. This would describe … More

Gravity. Without it there can’t be all those atoms crushed together and radiating electromagnetic radiation and particles and at such … More
