Primordial black holes older than the big bang could rewrite cosmology by providing evidence for a previous universe. It's a wild idea, but some physicists think we've got a chance of finding them

Most experts think we have to tweak general relativity to fit with quantum theory. Physicist Jonathan Oppenheim isn't so sure, which is why he’s made a 5000:1 bet that gravity isn’t a quantum force

Ancient philosopher Anaximander's discoveries about rain, wind and the cosmos may make him the true force behind modern science, argues physicist Carlo Rovelli in his newly republished first book

If we can’t measure something, we can’t know its true nature. This fundamental limitation hampers our understanding of the quantum world – but it doesn't preclude scientific thinking

When matter falls into a wormhole, the wormhole is expected to collapse – but a probe may be able to send a signal back through before it’s trapped on the other side

Inspired by the art of Cornelia Parker, physicist Carlo Rovelli explains the idea of relational quantum mechanics - and how it could resolve some key problems concerning the nature of reality.

Physicist Carlo Rovelli explains the strange principles of relational quantum mechanics - which says objects don't exist in their own right - and how it could unlock major progress in fundamental physics
