An IIT scientist proposes a twin universe born alongside ours, where time flows in reverse. This theory challenges the Big ...

At the center of every black hole is a point of infinite density, called a singularity. It's what gives black holes their strong gravitational pull. And for decades, scientists thought ...

With Stephen Hawking, he showed that if Albert Einstein’s general theory of relativity is correct, then there would be a singularity, a point of infinite density and space-time curvature ...
