Einstein explained gravity over one hundred years ago: He said it was warped space-time and told where to look for it, the bending of light in a gravitational field. He explained the bending of light was caused by space rising from the surface of the...

Push Gravity Sir Issac Newton said that space moves through matter freely without friction. By moving through space, you experience momentum, change in momentum lags behind the change in velocity. The momentum of an object applies pressure on the ...

Gravity is the result of warped space-time. Matter affected by gravity is the result of experiencing a change in uniform motion. Change in momentum lags behind a change in velocity. Matter on the surface of the Earth is applying pressure on the core:...

Are these events that common? I understand that colliding massive objects may appear as common when considering light=gravity speed, distance, the time of the event and the size of the universe but still, one event a week? ...

Ok maybe it was not an alien craft and the acceleration was outgassing... Did we detect deceleration when is was coming? (probably we don't have that data... bummer)

Science debate in action. I started to express a sense of skeptical curiosity when it appeared that LIGO was detecting several signals in a year or two. That would mean there are several black holes merging, maybe too many? ...

The conservation of energy is an absolute law, and yet it seems to fly in the face of things we observe every day. Sparks create a fire, which generates heat—manifest energy that wasn’t there before. A battery produces power. A nuclear bomb ...
