The top quark is about 100 trillion times heavier than the up quark. But why?
Paul Sutter received his Ph.D. in Physics from the University of Illinois at Urbana-Champaign in 2011. After spending three years at the Paris Institute of Astrophysics, he is now a visiting scholar at the Ohio State University's Center for Cosmology and Astro-Particle Physics. Sutter is the host of several podcasts and YouTube series, consults for TV and film productions, and frequently makes public appearances discussing physics and astronomy topics and the role science plays in society.
Mad scientists through the ages have dreamed of holding the world hostage by threatening to destroy the whole thing. Here's how that could work.
These tiny subatomic particles, showering down from the depths of space, continue to surprise (and annoy) physicists chasing them.
Brown dwarfs are cooler than stars but hotter than planets, and despite the name, they're not even very brown.
In the cosmos' most energetic events, we find some truly out-this-world methods of manufacturing radiation.
For the precocious hunter of off-Earth life, the Drake equation is the ever-ready, go-to toolkit for estimating just how (not) lonely humans are in the Milky Way galaxy. But it's not useful.
Magnets and the magnetic force are ubiquitous in our everyday lives, helping to guide us in unfamiliar territory and attach our kids' artwork to the fridge.
In 1980, physicist Alan Guth proposed a radical extension to the standard Big Bang model of the history of the universe, proposing a transformative event called cosmic inflation.
The "vanilla" Big Bang model, without any other additions or amendments, can't explain all the observations. Here's how it might have worked.
We've known for about 20 years that the expansion of our universe is accelerating, but how does the dark energy that causes it work?
Space is an amazing physics laboratory, because we can see stars and other objects behaving under extreme conditions.
When stars explode, they generate light that you can see across the universe, and they hold a key to measuring how the universe grows.
Entanglement is one of the most confusing aspects of quantum mechanics — a field of physics that isn't exactly known to be clear-cut, sensible, common-sense or easy-to-understand.
