Black Holes Course Us.

Space-Time is a sheath with four dimensions With Time as the fourth to length, width and breadth. A massive object causes curvature The way a rock does in a rubber sheet. The bigger the mass, the more the depression. If the massive object accelerated, It would produce gravitational waves The way a speed boat makes wake in water. Black holes orbit one another, circles, Come closer, speed up, spiral in, and colloid With a huge burst of energy released. The effect is the gravitational waves. These waves penetrate any in the path. The Gravity itself is the effect of The curved geometry of Space-Time. Waves from black holes course us on the earth.
