Stephen Hawking's most famous theory about black holes has just been given a sinister update — one that proclaims that everything in the universe is doomed to evaporate.
In 1974, Hawking proposed that black holes eventually evaporate by losing what's now known as Hawking radiation — a gradual draining of energy in the form of light particles that spring up around black holes' immensely powerful gravitational fields. Now, a new update to the theory has suggested that Hawking radiation isn't just created by stealing energy from black holes, but from all objects with enough mass.
