Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations ... Still, others question whether Einstein’s theory of general relativity needs a rewrite.

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass ... speed limit — nothing with mass can travel faster than light. Einstein’s equation ...

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of ...

SciFi books and films never explain how faster-than-light speed works. Wormholes are one solution, but there are problems. Like, how can they exist?

Across the pages of Hindu scriptures, there are tales where time bends, realities duplicate, and consciousness transcends the ...

When something travels near the speed of light, strange things happen—not just to time and space ... contraction—a key part of Einstein’s theory of special relativity—doesn’t actually ...

The Terrell-Penrose effect, predicted in 1959, suggests that objects moving at speeds close to that of light appear rotated.

This is the central consequence of Albert Einstein's special theory of relativity. The object then has a different length than when it is at rest, and time passes differently for the object than ...

Einstein’s Special Theory of Relativity has long baffled and amazed scientists. It explains how objects behave when they move ...
