A Typical Neutron Star Is Only 13.6 Miles Wide, According to New Ultra-Precise Measurement

A Typical Neutron Star Is Only 13.6 Miles Wide, According to New Ultra-Precise Measurement

A typical neutron star measures 22 kilometers (13.6 miles) wide, according to new research. It’s the most accurate measurement yet of these highly compact, super-dense objects.

If black holes are the most extreme phenomena in the universe, then neutron stars have to be a close second (unless quark stars exist, which has yet to be confirmed). Formed in the wake of a supernova explosion (when a...

Scientists Figured Out the Perfect Recipe For Making Gigantic Soap Bubbles

Scientists Figured Out the Perfect Recipe For Making Gigantic Soap Bubbles

Now that most of the world’s major problems have been resolved, science is turning its attention to the less pressing issues plaguing humanity, including how to mix up the perfect soapy solution for making gigantic bubbles that don’t immediately pop.

Scientists have actually been interested in bubbles dating back to the 1800s, and why shouldn’t they be? It seems completely illogical that a...

'Remarkable' Mathematical Proof Describes How to Solve Seemingly Impossible Computing Problem

'Remarkable' Mathematical Proof Describes How to Solve Seemingly Impossible Computing Problem

You enter a cave. At the end of a dark corridor, you encounter a pair of sealed chambers. Inside each chamber is an all-knowing wizard. The prophecy says that with these oracles’ help, you can learn the answers to unanswerable problems. But there’s a catch: The oracles don’t always tell the truth. And though they cannot communicate with each other, their seemingly random responses to your...

Has Hubble Detected Rogue Clumps of Dark Matter?

Has Hubble Detected Rogue Clumps of Dark Matter?

Scientists using the Hubble Space Telescope have discovered evidence of small clumps of dark matter warping the light from distant quasars.

Regular matter seems to form only a small part of the universe—much more of the matter seems to be “dark” stuff that influences regular matter via gravity but can’t be detected directly. The most widely accepted theory to explain dark matter suggests that...

CERN's Oldest Particle Accelerator Is Still Running 60 Years Later

CERN's Oldest Particle Accelerator Is Still Running 60 Years Later

The oldest particle accelerator at CERN, home to the world’s most powerful particle accelerator, is celebrating its 60th birthday. It’s still running.

The Proton Synchrotron (PS) accelerated its first protons on November 24, 1959. It was the world’s highest-energy accelerator when it first began running. Though it’s since lost the title, today it supplies protons or heavy ions to a number of...

Let's Pump the Brakes on the So-Called 'No-Brainer Nobel Prize'

Researchers in Hungary have published the exciting new claim that they’ve discovered a new subatomic particle, but it’s nowhere near time to start talking about Nobel Prizes, as CNN (and now everyone who syndicates them) has done.

Since 2015, the team at the Institute of Nuclear Research (Atomki) and the University of Debrecen claims to have spotted a mysterious correlation between pairs of...

Google Scientists Are Using Quantum Computers to Study Wormholes

Google Scientists Are Using Quantum Computers to Study Wormholes

Google researchers are figuring out how to study some of the weirdest theorized physics phenomena, like wormholes that link pairs of black holes, using experiments in a lab.

One central question driving theoretical physics today is how to use the same theory to explain both gravity and the rules that atoms follow, called quantum mechanics. The two haven’t played nicely yet, since gravity is an...

First Look at 'Sycamore,' Google's Quantum Computer

Between the mountainous and coastal vistas of Goleta, California, sits an unassuming office on the side of a building next to the freeway. It could belong to any Southern California company; workers sit in gray cubicles beneath fluorescent lights, and there’s a rack to hold employees’ bikes and surfboards. But at those desks are physicists and computer scientists developing a computer like...
