In the early stages of the hot Big Bang, matter and antimatter were (almost) balanced. After a brief while, matter won out. Here’s how.

Perhaps the most well-known equation in all of physics is Einstein’s E = mc². Does mass or energy increase, then, near the speed of light?

Einstein’s most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.

If nature were perfectly deterministic, atoms would almost instantly all collapse. Here’s how Heisenberg uncertainty saves the atom.

Over a century after we first unlocked the secrets of the quantum universe, people find it more puzzling than ever. Can we make sense of it?

More than any other equation in physics, E = mc² is recognizable and profound. But what do we actually learn about reality from it?

If it weren’t for the intricate rules of quantum physics, we wouldn’t have formed neutral atoms “only” ~380,000 years after the Big Bang.

The mass that gravitates and the mass that resists motion are, somehow, the same mass. But even Einstein didn’t know why this is so.

Scientists just viewed one of the tiniest, most isolated, lowest-mass galaxies ever found with JWST. Despite all odds, it’s still growing.

Often viewed as a purely theoretical, calculational tool only, direct observation of the Lamb Shift proved their very real existence.

Research suggests curiosity triggers parts of the brain associated with anticipation, making answers more rewarding once discovered.

Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it’s magical.

Sunita Sah hopes that by redefining defiance, we can build societies that allow people to live more authentic lives.

The fact that our Universe’s expansion is accelerating implies that dark energy exists. But could it be even weirder than we’ve imagined?

Nurture your passions instead.

Without wormholes, warp drive, or some type of new matter, energy, or physics, everyone is limited by the speed of light. Or are they?

To understand others, you need to see past their fleeting emotions. You must perceive who they are as people.

You can only create or destroy matter by creating or destroying equal amounts of antimatter. So how did we become a matter-rich Universe?

There’s value to be found in the arguments that make you uncomfortable — especially in a culture that has trained us to avoid them.

In “Enough Is Enuf,” Gabe Henry traces the history of simplified spelling movements and the lessons they teach us about language.

Rich is brilliant at his job. He completes work in half the time of his coworkers. Should he have to sit at his desk just as long?

A great many cosmic puzzles still remain unsolved. By embracing a broad and varied approach, particle physics heads toward a bright future.

Executive coach Jodi Wellman explains how to “make it to the end with no regrets.”

Stanford psychologist Jamil Zaki discusses the dangers of cynicism and how skepticism can invigorate our relationships and communities.

Lord Kelvin is thought to have said there was nothing new to discover in physics. His real view was the opposite.

What would it take to create a truly intelligent microbot, one that can operate independently?

The AI is helping Twitter users plot movies, design meal plans, and more.

Whether you run the clock forward or backward, most of us expect the laws of physics to be the same. A 2012 experiment showed otherwise.

If you’re out on a walk, you will see a different world than your dog, a bee, or an ant. Here are three reasons why that matters.

For the first time in nearly 1500 years, fewer than half the people in England and Wales consider themselves Christian.
