14 DAY TRIAL // Black holes are basically places in space where gravity is so insanely strong that loads of matter gets squeezed into a tiny spot that is mind-bogglingly compact. Mind you, the gravitational pull of black holes is so strong that not even light can escape them.
Pretty much all galaxies have a black hole at their core. Even our Milky Way has one and so does neighboring Andromeda, astronomers say. Luckily, we, Earth dwellers, don't have to worry about getting sucked in by either of them.
Then again, just in case some of you wish to know what life near a black hole would be like, here's a video discussing what might happen if a black hole were to suddenly and without warning appear somewhere on Earth in an odd place like, say, your pocket.
However, a black hole with a mass similar to that of a coin would instantly perish and, in the process, produce three times more energy than the Hiroshima and Nagasaki bombs together. An explosion would happen and our planet would be, well, destroyed.
On the other hand, a black hole with the diameter of a coin would exert such a strong gravitational pull that the world as we know it would get ripped apart, ourselves included. So, no, this isn't a very appealing scenario either.
