The first detections were incredible. But now the real fun — and the real science — truly begins. On August 17, the signals from two merging neutron stars reached Earth after a journey of 130 […]

Would there be only blackness past the event horizon? Or something more? Black holes are some of the most perplexing objects in the entire Universe. Objects so dense, where gravitation […]
We know that it’s ‘the red planet’ because of the iron in its soil. But why, with such a thin, carbon dioxide atmosphere, is the martian sky so red and bright? […]
While it’s reasonable to trust that science will eventually answer our unsolved questions, assuming that it has all of the answers right now is not.
One of inflation’s cofounders has turned his back on the idea. But practically no one else is following him. Is he right? This article was written by Sabine Hossenfelder. Sabine is […]
We’re taught that the most massive stars in the Universe all die in supernovae. We were taught wrong. Create a star that’s massive enough, and it won’t go out with a […]
Unless you can make a force that travels faster than the speed of light, a singularity is inevitable. The more mass you place into a small volume of space, the […]
Instead of nearly-circular ellipses, comets are extraordinarily elongated, or even on an exit path. Why so different? When you look at how the planets orbit in our Solar System, the […]
The indirectly find was completely unexpected, and, if it holds up, could give the James Webb Space Telescope its first tantalizing target. In the quest to understand our Universe, and […]
If it were, we wouldn’t be here. But there’s a scientific answer that’s been spectacularly confirmed. When we examine our Universe, looking out at the planets, stars, galaxies, and vast […]
Last week, the crew found themselves in the mirror Universe. Here’s what science has to say about that. Star Trek: Discovery entered their midseason hiatus on a terrific cliffhanger: they had […]
Where gravity comes from has been an utter mystery. String theory offers an explanation.
BASE particle physicists have discovered a very precise way to examine antimatter.
In 1990, the Hubble Space Telescope was launched, leading to a revolution in astronomy. But for many purposes, Earth is still the best place to be. When you think about what’s […]
99 years ago, General Relativity was still unproven. During the 1918 eclipse, a small team of Americans almost changed that. “Astronomers are greatly disappointed when, having traveled halfway around the world […]
The theory could solve certain stubborn physics questions such as, where’s all the antimatter.
Understanding this evaluation process may help us create more sophisticated A.I.
If you can’t explain the astrophysical signal that you see and cry ‘dark matter,’ chances are you’re not thinking hard enough. Despite our knowledge of the laws of physics, and the […]
If space were really curved due to matter and energy, we should see light deflect. A solar eclipse provides the perfect opportunity. “Eddington had needed to make significant corrections to […]
Einstein believed in the unseen—like gravitational waves, ripples in space and time. Now, we can see this, as shown by the 2017 Nobel Prize physics winners.
The four fundamental forces might have been just a single, unified one in the very early Universe. Could that be true? “Those who begin coercive elimination of dissent soon find themselves […]
There’s something all of us—physicists included—are getting wrong about dark matter, says Neil deGrasse Tyson.

They seem almost indistinguishable in some regards, but only one of them represents our physical Universe. When it comes to describing the physical world, we can do it anecdotally, as […]
Theoretical physicist and cosmologist Lawrence M. Krauss spoke at CSICon 2016 about scientists’ attempt to look back in time to the beginning of our universe.
If you don’t learn this one lesson, you’ll not only never be good at science, you’ll never learn anything new. “Right is right even if no one is doing it; wrong […]
Researchers said this feat concludes “one of the major challenges in modern cosmology.”
There’s no way to frame this as anything other than a disaster for humanity. This article was originally written one week ago, on the day the FY2019 budget was released […]
Figure skating has a lot to do with physics, and here’s what we mean. Also, what’s the difference between all those figure-skating jumps?
The Universe may defy our intuition, but that’s what science is for! If you take a look out at the Universe, and in every direction you look, you see objects rushing […]
