FINDING evidence to back up a theory of everything was always going to be difficult. Now two particle physicists say they may have tracked some down – lurking inside black holes.
The pair’s calculations have revealed that black holes might be harbouring enigmatic hypothetical entities called magnetic monopoles. If they are, not only would physicists have stumbled upon a key ingredient for a theory of everything, but it may explain why some black holes rotate.
Physicist first proposed magnetic monopoles in 1931. Unlike magnetic poles, which come in north and south pairs, monopoles carry just a single…
