Speed of Light

Calculating the most influential scientific equations is no easy task. But these five certainly rank in the top tier.

It's hard to say at this point, but a crucial first step is to establish whether they exist so any future arrival won't come as a complete surprise

An MIT study narrows the search for particles called ultralight bosons, which, if they exist, could be an important component of dark matter. Certain ultralight bosons would be expected to put the brakes on the spin of black holes, but the new results show no such slowdown.

The muon is a tiny particle, but it has the giant potential to upend our understanding of the subatomic world and reveal an undiscovered type of fundamental physics.

By bert hubert bert@hubertnet.nl / @PowerDNS_Bert / https://galmon.eu/ Late July 2019, Galileo, "the European GPS" suffered from a week long outage. I'm a proud European, and I think we should have our own well-functioning navigation system, so I tried to figure out what was going on. Surely someone was monitoring this stuff in public? I come from the internet where we monitor all the things, if someone asked for…

If you take enough mass and compress it into a small enough volume of space, you'll inevitably form a black hole. Any mass in the Universe will curve the fabric of spacetime around it, and the more…

Ask anyone — even someone with no background in science — to name something that Einstein did, and odds are they'll come back with his most famous equation: E = mc². In plain English, it tells us…

And one for the conspiracy skeptic.

Shooting beams of ions at proton clouds at the speed of light provides a clearer view of nuclear structure, MIT physicists report. Their technique may help researchers map the inner workings of neutron stars.

Navigation for starship commanders just got easier.

Scientists from the international Event Horizon Telescope (EHT) collaboration announced Wednesday that they had been able to map the magnetic fields around a black hole using polarized light waves …

Physicists could be on the verge of a major breakthrough as new results hint at a challenge to the standard model of particle physics.

The AV landscape is vast. What started as a moonshot project at Google X a decade ago has morphed into a respectable tech field in its own right, with plenty of startups occupying all kinds of niches…

The Atlantic covers news, politics, culture, technology, health, and more, through its articles, podcasts, videos, and flagship magazine.

New research solves a decades-long riddle: from where do the highest-energy cosmic rays originate? Even supernovae - exploding stars - can't explain them. Now it seems these sorts of cosmic rays may come from clusters of young, hot, massive stars.

We humans aren't complete slaves to time. We've devised ways to pack an extra hour of sunshine into our day, thanks to daylight saving time. But who came up with this idea and why do so many people loathe it?

For decades, researchers assumed the cosmic rays that regularly bombard Earth from the far reaches of the galaxy are born when stars go supernova—when they grow too massive to support the fusion occurring at their cores and explode.

The source of the 160,000-light-year-long jet of particles is PSO J352.4034-15.3373 (PJ352-15 for short), a rapidly growing supermassive black hole, or quasar, located about 12.7 billion light-years away in the constellation of Aquarius.

Scientists were able to capture a high-energy particle in the South Pole.
