Stephen Hawking wants live forever on this commemorative black hole coin



Stephen Hawking is immortal, but now his work is being written down on a coin that should last until all the black holes in the universe evaporate.

The UK Royal Mint has released the most appropriate coin ever to keep the late physicist's memory alive forever, or at least as long as Earth is around. It's kind of like you can fit in your pocket.

"I wanted to fit a big black hole." on the tiny coin and wish [Hawking] chortling at the thought, "designer Edwina Ellis told the BBC about the 50p (about 72 cents) coin they wanted to embody how he made them accessible, engaging and relatable

About these black holes evaporating-this is where entropy comes in. Entropy is how it is. Because nothing, not even light, can escape the extreme gravitational force of a black hole, Hawking started to wonder what that did to entropy. This is how the concept of Hawking radiation emerged. Black holes, he believed, must be loose and thus radiate matter from their surfaces.

The equation on the coin merges general relativity (laws of gravity) and quantum mechanics (laws of the tiniest particles) to explain how even black holes will dissipate into the ether over billions and billions of years.

"It's a great privilege to be featured on a coin," said Hawking's daughter Lucy, "and I hope my father would have pleased to see Sir Isaac Newton and Charles Darwin as" who made it on to money. "

If you do not live in the UK, that does not mean that are light-years away. Get one right now from the Royal Mint's website and put a black hole in your pocket.
