Scientists are on the verge of being able to detect the "memory" left behind by gravitational waves.
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.
A new study has called into question the prevailing notion that the universe is "flat." The stakes of this cosmological debate are huge.
At some point, the rules of the subatomic give way to the rules of the macroscopic. But how? We're not exactly sure, and it's been a long, strange journey in trying to answer that question.
An ambitious new fleet of spacecraft could reveal whether space-time is smooth or chunky, and in doing so the ultimate nature of reality.
Two legendary scientists gave us an understanding of gravity, and how to apply that understanding to the motion of the sun, planets and moons.
A brand-new particle has possibly emerged and is altering the future destiny of our entire cosmos, a physicist says.
Different measurements of the universe's expansion yield different results. Are we getting something wrong, or do we need brand-new physics to figure it out?
You might not recognize Peebles' name, but he theorized the existence of dark matter and has been a key player in painting the portrait of the universe that we now understand.
The 1995 discovery showed that the sun isn't the only star to host a family of planets — something we had long figured but never demonstrated — and also that the universe is really, really weird.
Obviously, some chain of unfortunate events led to the ejection of 'Oumuamua from its home system. But what could possibly cause such a catastrophe?
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.
