It’s the weirdest thing: quantum theory works incredibly well in practice. It powers devices ranging from MRI machines to lasers and the very computer you’re reading this on. But even after 100 years, ...

For nearly a hundred years, one of the most celebrated minds in science, Albert Einstein, had a lingering quantum thought ...

What happens after death? This age-old question has intrigued humanity for centuries, with countless theories from religious, ...

Decades ago, a renegade physicist suggested that gravity isn't so much a force as just a byproduct of the universe's tendency ...

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted ...

This quantum balancing act—long debated by Einstein and Bohr—was tested without traditional “spring” components, instead relying on atomic “fuzziness” to confirm Bohr’s view: you can’t observe both ...

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...

The imaginations of scientists and sci-fi lovers have just been stimulated with the news that a warp drive is being studied ...

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

The mind-bending concept of time dilation results from a seemingly harmless assumption—that the speed of light is the same ...

Predicted by Albert Einstein in 1916 as a consequence of his general theory of relativity, they were dismissed even by Einstein himself as too faint to ever be detected. For nearly a century, they ...
