They're huge. They're voracious. They're blacker than a panther on a moonless night. They're black holes, the mind-bending, space-warping cosmic objects with gravity so insanely powerful that even a beam of light that wanders too close will be sucked in, never to emerge. Einstein's theory of general relativity predicted they might exist, but the great physicist himself doubted it would really happen.

Bertha! is that you?
Think about it.Literally the heart of the universe.However,suggesting that nothing can escape it is incorrect.Light or physical objects drawn into a black hole must exit at some point.To space travelers,learning to navigate black holes is the key to long distance space travel.By allowing their crafts to be drawn in to the black hole by it's gravitational pull,they can emerge light years from where they started.This they have accomplished in what seems like a few minutes to the space travelers.Earth is too far from the nearest black hole for humans to take advantage of one,unless they generate their own artificial black hole.
lol smoking weed?
God created the heavens and the earth. The heavens declare His Glory. Eye has not seen; nor ear heard what God has prepared for those who are believers. WOW !!!
I am a former Hubble engineer. Hubble permitted people to "look back in time" because it collected light output from a long time ago. It's not a difficult concept. You just look at a source, calculate how far away it came from, and apply the speed of light.
