Interstellar flight is a real pain in the neck.
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.
There are some odd little particles out there that are bound by the strong nuclear force, but physicists can barely get a glimpse of them before they flit out of existence.
A giant linear collider the size of Manhattan could finally help us find new physics, scientists argue.
Our lives here on Earth are small and insignificant and inconsequential — but only in a certain frame of reference, and that frame of reference doesn't necessarily apply to cosmic scales.
Moons of "hot Jupiter" alien worlds may detach from their parent planets and begin orbiting stars on their own.
Astrophysicist Paul Sutter breaks down the science behind NASA's historic Apollo moon missions for Space.com. Tune in here!
The universe really likes its information — but black holes pose a huge paradox physicists can't yet solve.
At the very largest scales — zooming out from solar systems, stellar clusters and even galaxies — a surprising pattern emerges in nature.
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.
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.
