What if black holes aren't black holes at all, but rather the cosmic equivalent of fuzzy, vibrating balls of string?
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.
The EmDrive doesn't just violate our fundamental understanding of the universe; the experiments that claim to measure an effect haven't been replicated. When it comes to the EmDrive, keep dreaming.
A pair of astronomers is advocating a daring new research program: to turn our widening search for life beyond Earth into a hunt for dark matter.
Our sun's death is a long way off — about 4.5 billion years, give or take — but someday it's going to happen, and what then for our solar system?
At the center of a black hole, matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down.
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.
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 recent survey sheds some light on what the mighty Aztecs thought about the rare and wonderful solar eclipses.
For all the biological activity on our homeworld, we're not the only interesting planet orbiting the sun. There are some other equally amazing places in the solar system. Here is just a sampling.
Astronomers recently spotted perhaps the strangest white dwarf yet: a dead star the spins twice a second, sucking down material from a nearby companion as it goes.
Life on Earth can seem pretty hazardous, but if you ask astrophysicist Paul Sutter, it's still safer than anywhere else in the universe.
