A bold new quantum theory of gravity may finally bridge the long-standing rift between Einstein’s general relativity and quantum field theory. This potential "Theory of Everything" could answer some o ...

The universe may not be infinite or flat. Physicist Glenn Starkman and his team propose it could have a complex topology, possibly shaped like a 3-torus, resembling a hyperdimensional doughnut.

Inflation was invented to explain a couple of features of the universe that are really hard to explain without it. The first is that Einstein’s general theory of relativity famously makes mass ...
