Five-dimensional black hole could 'break' general relativity

Researchers have shown how a bizarrely shaped black hole could cause Einstein's general theory of relativity, a foundation of modern physics, to break down. However, such an object could only exist in a universe with five ...

You don't exist in an infinite number of places, say scientists

(Phys.org)—If you've read about how modern cosmology may imply that, in an infinite universe, the existence of planets and the life forms that live on them must be repeated an infinite number of times, you may have been ...
