You might think that we live in a three dimensional Universe based on space alone. But you cannot leave time out of it. If you were asked to describe how you […]

All protons have the same exact mass as every other proton. For particles like the Higgs boson, this isn’t true. One of the most puzzling aspects of quantum physics is how […]
It’s massive, it’s transparent, and it’s ubiquitous. But so is our ignorance. When we look out at the Universe, we have two general ways to try and make sense of […]
If dark matter is fundamentally different from the normal matter we know, there should be a way to test it. Here are the results. Dark matter — despite the enormous indirect evidence for […]
The fine Facebook just paid was huge, but many in tech say it wasn’t nearly enough to protect your data.
Discovered by NASA’s Chandra X-ray observatory, it’s powered by a supermassive black hole. 2019 marks 20 years of NASA’s Chandra, humanity’s most powerful X-ray observatory. Artist illustration of the Chandra X-ray […]
They said the “missing half” of the Universe’s matter was just found. But what they found barely makes a dent to the big picture. When we look up into the great […]
It has already found several bizarre planets outside of our solar system.
Black holes are regions of extreme gravity, but dark matter barely interacts at all. Do they play well together? Black holes are some of the most extreme objects in the […]
The small step that one man took would never have happened without this narrow escape. On July 20, 1969, history was made as humanity set foot on the Moon for the […]
Think they all burn through their fuel, die, and leave white dwarfs, neutron stars, or black holes behind? Think again. The day will come when our Sun, like most stars, can […]
Even if you remove everything you can from the Universe, some energy will still remain. Here’s what that means. Imagine, if you can, what it would mean to have a Universe […]
Astronomy’s enduring quest is to go farther, fainter, and more detailed than ever before. Here’s the edge of the cosmic frontier. Astronomers have always sought to push back the viewable […]
Not everything needs a medium to travel through. If we can overcome that assumption, we don’t need the aether at all. All throughout the Universe, different types of signals propagate. Some […]
With the discovery of the Higgs boson, the Standard Model is now complete. Can we be sure there isn’t another generation of particles out there? The Universe, at a fundamental level, […]
The Universe is filled with something, as opposed to nothing, and scientists don’t understand it. When we look around at the Universe: at the planets and stars, at the galaxies […]
Forget Copenhagen, Many-Worlds, Pilot Waves and all the others. What you’re left with is reality. When it comes to understanding the Universe, scientists have traditionally taken two approaches in tandem with […]
How does one supernova get so bright, so energetic, and so massive? It’s a spectacular mystery to solve. On February 22, 2016, one of humanity’s automated sky-scanning telescopes — the Pan-STARRS Survey for […]
Was it a real thing? And the Wise Men? Or are they just myths?
It’s an incredibly useful approximation. But the truth takes us far deeper. Anyone who’s ever taken a physics course has learned the same myth for centuries now: that any object thrown, […]
There is a fundamental difference between matter and antimatter. But not enough of one to explain our Universe. Our Universe is a vast and enormous place, and if there’s one […]
The potential of blockchain might have been ruined for you by your unemployed cousin who wears Balenciagas to Thanksgiving dinner and told you to enter into the cryptocurrency market at […]
Kepler showed us that the Universe is full of planets around other stars. TESS is giving us our next great leap. It’s been nearly a decade since NASA’s Kepler mission first […]
We may never have to get more than one flu shot again.
Black hole mergers are some of the most energetic events in the Universe. Could the gravitational waves they produce ever harm us? The Universe is not a static, stable place. Out […]
Ideas are plentiful; execution is another story.
We know that life is possible on an Earth-like world around a Sun-like star. But can it find a way on a Super-Earth? When it comes to the origin of […]
