Why does gravity have pull but no push? What is mean by gravitational intensity? When standing on earth, why do we notice the force of gravity around us constantly but not the electric force? What does light do when it passes from air into water? and why? What are the different theories...
Gravity and Black Holes A black hole is a region of space where the gravitational pull is so strong that not even light can escape from it. The point of no return around a black hole is known as the event horizon. Once an object crosses this boundary, it is inevitably pulled into the...
A black hole is so tightly packed that its gravity absorbs everything — even light. The light from a black hole can never come back to your eyes. That’s why you see nothing but blackness. So the next time, you look up at the night sky, remember: there’s more in the sky than...
The Gravia lamp relies on a much simpler concept: Gravity pulls objects downward. The lamp is a standing floor lamp, 58 inches (147 centimeters) tall and cylinder-shaped. Inside the cylinder, there are several basic parts involved in creating light: brass weights, a ball screw, a drive gear...
But more likely the gravity of Jupiter is to blame for Ganymede’s continuing geological activity. Ganymede is close enough to Jupiter that tidal forces from the giant planet may have episodically heated its interior and triggered major convulsions on its crust....
(3) We cannot see light when we look at a black hole because___. A. most black holes are so far away. B. the strong gravity sucks the light inward. C. as the star’s gases burn, it stops giving off heat and light. D. as a star cools, its outer layers pull in toward its...

What does this have to do with time? Remember: Any event that occurs in the universe has to involve both space and time. Gravity doesn't just pull on space; it also pulls on time. You wouldn't be able to notice minute changes in the flow of time, but a sufficiently massive object...
