Astroquizzical: How Does Gravity Escape From A Black Hole?

“Information doesn’t always travel at the speed of light, though — depending on the environment that the information is traveling through, and the form of that information (which is not always light), the speed of information can proceed at speeds that are much slower than the speed of light. The speed of light in a vacuum seems to be a hard upper limit that nothing can surpass, but if your information is in the form of a compression wave, like sound, then the information travels at the speed of sound in that medium.”

There’s something puzzling about black holes, if you stop to consider it. On the one hand, they’re objects so massive and dense — compacted into such a small region of space — that nothing can escape from it, not even light. That’s the definition of a black hole, and why “black” is in the name. But gravity also moves at the speed of light, and yet the gravitational influence of a black hole has absolutely no problem extending not only beyond the event horizon, but infinite distances out into the abyss of space. Jillian Scudder has the answer to this puzzling conundrum!

One of the biggest mysteries in modern physics may have just been solved. The scientific community is abuzz with rumors that physicists have finally detected gravitational waves, fluctuations in the curvature of space-time that move at the speed of light throughout the galaxy. Noted physicist Albert Einstein first predicted them in 1916, theorizing they might explain how mass affects the very fabric of space-time. The discovery of the gravitational waves would be one of the biggest discoveries in physics in history
