Albert Einstein was intrigued by a simple puzzle: an old car must travel 2 miles at an average of 30 mph. The twist? Its structure makes the solution impossible. Can you solve it?

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

Right at the brink of a black hole, gravity twists space and time so violently that ordinary physics starts to fall apart.

When black holes collide, the impact radiates into space like the sound of a bell in the form of gravitational waves. But ...

What if the Big Bang wasn’t truly the beginning? A team of cosmologists is using the power of supercomputers to push past the limits of Einstein’s equations and explore mysteries once thought ...

A new review argues that modern numerical relativity can push cosmology past its usual shortcuts and test ideas about what, if anything, came before the Big Bang. The approach is simple to state and ...

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed that far back in time. Yet a new paper published in Living Reviews in ...
