Stephen Hawking has made a compelling case that black holes ultimately evaporate, however the time scales are past our skill to detect it. A brand new paper means that primordial black holes passing by the Photo voltaic System could possibly be releasing positron emissions that might be detectable after they cross as much as 10 AU from Earth. If discovered, they might verify Hawking’s theories and supply a proof for darkish matter. Sadly, our greatest know-how is not fairly delicate sufficient.
