GRAVITY WAVES……WHAT ARE THEY? After searching for 30 years, scientists have found and measured gravity waves. This was announced yesterday. Gravity is the pull between the sun and the earth, or the pull between a human and the earth. Einstein one-hundred years ago (1916) published the General Theory of Relativity. In it he predicted gravity waves that would spread across the universe like ripples from a stone dropped into a pond. Except they travel at the speed of light.

But to create a gravity wave, you need to suddenly shift a very heavy object, such as a black hole. A black hole may be 30 times the mass of the sun, or almost ten million times the mass of the earth, but only 20 miles in diameter, which is mind-blowing.… More “Einstein and discovery of gravity waves”
