Albert Einstein, everyone’s favorite wild-haired genius with a mischievous grin, is more than just a pop culture icon whose legend lives on today. He’s arguably the most influential scientist of the ...

Wormholes, conceptual tunnels slicing through spacetime, offer a theoretical shortcut between two distant cosmic points.

Twin black hole collisions detected in 2024 have provided the sharpest-ever test of Einstein’s theory while revealing new ...

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of ...

Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the driving force behind creation. Their simulations show that gravity and ...

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

Einstein was a great thinker who made plenty of mistakes—errors that sometimes led to more meaningful discoveries in physics, ...

The universe rarely fails to amaze. One of its latest surprises—nicknamed the “Einstein zig-zag”—reveals a stunning arrangement of galaxies and a distant quasar. Together, they produce a gravitational ...

It's a plot device beloved by science fiction: our entire universe might be a simulation running on some advanced ...

The faster you move, the stranger time becomes. By imagining how light travels to two people moving at different speeds, Einstein showed that time isn’t absolute. His thought experiment revealed that ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...
