In the very early Universe, practically all particles were massless. Then the Higgs symmetry broke, and suddenly everything was different.

Maintain peace of mind during tax season by correctly filling out your W-4.
In our Universe, matter is made of particles, while antimatter is made of antiparticles. But sometimes, the physical lines get real blurry.
There's a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.
On New Year's Eve 1899, the captain of this Pacific steamliner sailed into history. Or did he?
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.
For decades, theorists have been cooking up "theories of everything" to explain our Universe. Are all of them completely off-track?
Freethink's weekly countdown of the biggest space news, featuring Starship's second test flight, a new "dark mysteries" telescope, and more.
Fermilab's TeVatron just released the best mass measurement of the W-boson, ever. Here's what doesn't add up.
In general relativity, matter and energy curve spacetime, which we experience as gravity. Why can't there be an "antigravity" force?
The zero-point energy of empty space is not zero. Even with all the physics we know, we have no idea how to calculate what it ought to be.
Music is part of the human experience, which is why some philosophers have written about it. Some had wacky ideas.
At a fundamental level, only a few particles and forces govern all of reality. How do their combinations create human consciousness?
It's nearly 20,000 miles long.
Origin of life studies have always focused on a set of strict environments that could give rise to life. Ante-life opens new possibilities.
Some constants, like the speed of light, exist with no underlying explanation. How many "fundamental constants" does our Universe require?
"Conceptual isolation" offers an agreeable solution.
Even without the greatest individual scientist of all, every one of his great scientific advances would still have occurred. Eventually.
This collection of learning and development quotes serves as a reminder of the meaning and purpose behind this important work.
In 1903, a Vermont doctor bet $50 that he could cross America by car. It took him 63 days, $8,000, and 600 gallons of gas.
Forgetting and misremembering are the building blocks of creativity and imagination.
It could evolve, strengthen, decay, or not be alone. Our known Universe contains matter, radiation, and dark energy. While matter (both normal and dark) and radiation become less dense as […]
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at even higher energies, something even greater happens?
Despite the Sun's high core temperatures, particles can't quite overcome their mutual electric repulsion. Good thing for quantum physics!
The tonal Native American language differentiates words based on pitch and makes Spanish conjugation look like child’s play.
In our common experience, you can't get something for nothing. In the quantum realm, something really can emerge from nothing.
Each year in mid-August, Earth plows through the debris stream of an enormous comet, creating the Perseids. 2023's show will be magnificent!
Four key components to guide the creation of emotional intelligence training for leaders.
Move over, IC 1101. You may be impressively large, but you never stood a chance against the largest known galaxy: Alcyoneus.
2023's Nobel Prize was awarded for studying physics on tiny, attosecond-level timescales. Too bad that particle physics happens even faster.
