It's a perennial sci-fi favorite: other worlds, other universes, other possibilities, right beyond the bounds of the known cosmos or just a flick of a magic device away.
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.
All four known forces of nature have their own unique place — and the strong nuclear force governs the very small.
Neutrinos are the changelings of the subatomic world, but physicists are getting closer to pinning down the particles' true identities.
The concept of atoms had been floating around off and on for a few millennia, but it took some clever experimentation to pinpoint their existence.
A recent search for oddball supersymmetric particles, which could explain some of the weirdness of the universe, came up empty-handed.
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.
