Physicists suggest harnessing the gravitational pull of black holes to create ferocious particle accelerators. The trick? Carefully set everything up so the particles don't get lost forever.
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.
In one upside-down, hypothetical version of the universe, a bizarre type of black hole could exist that is stranger than an M.C. Escher sketch: charged black holes.
Black holes can get big … really big. But just how big? It's possible they could top out at over a trillion times more massive than the sun.
A physicist proposes that the moon is a great place to build a particle collider and conduct high-energy physics experiments.
Physicists are figuring out how close you can get to a black hole before you are unlikely to escape. That threshold is called the innermost stable circular orbit (ISCO).
Magnetars — highly magnetized, rapidly rotating super-dense stars — are among the most enigmatic creatures to inhabit the cosmos and their origins are shrouded in mystery.
It was a big moment for our cosmos when the first stars awoke, but it's an elusive one for scientists.
String theory is a powerful idea, unfinished and untested, but one that has persisted for decades despite inauspicious beginnings.
The world of the teensy-tiny, the quantum realm, could have a favorite flavor. Here's why that's a big deal.
An ambitious new fleet of spacecraft could reveal whether space-time is smooth or chunky, and in doing so the ultimate nature of reality.
