Excellent article in @sciam about the impending opportunity to redefine the second using optical clocks, including the friendly competition between ions and neutral atoms. scientificamerican.com/artic…

World’s Most Accurate Clocks Could Redefine Time

New atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change

Yeah, if I had to bet I'd say the path to any viable interplanetary or interstellar future doesn't run through cryptocoin grifts, disinformation memes, pay-to-win video games, grievance-based policymaking, and a shameless embrace of neofascism. SpaceX makes nice rockets, though.

NEW: Does Planet 9 exist? No telescope has been capable of finding it—but in 2025, the Rubin Observatory will come online, and with its remarkable eye, it will find out, once and for all, if the elusive world is truly there. My cover story for @sciam: scientificamerican.com/artic…

If Planet Nine Exists, We’ll Find It Soon

If there’s a hidden world in the solar system, a new telescope should find it

It's hard to believe there could be a giant planet in the solar system that we haven't seen. But these are exciting times! We should know within the next two years either way 🪐

A hidden form of dark energy might have reshaped the early universe. By Nobel laureate Adam Riess and theoretical physicist Marc Kamionkowski: scientificamerican.com/artic…

Could ‘early dark energy’ resolve the mystery of cosmic expansion?

Estimates of how fast the universe is expanding disagree. Could a new form of dark energy resolve the problem?

It's so amazing to me that humans have built machines that can detect something so small and rare that it has less than 1 in 10 billion chances of happening: scientificamerican.com/artic…

First Observation of One-in-10-Billion Particle Decay Hints at Hidden Physics

Physicists have detected a long-sought particle process that may suggest new forces and particles exist in the universe

The rapid surge in orbital launches could add 50,000 satellites by 2030, increasing risks like space junk, metallic pollution, and threats to science, security, and the environment. Join Space & Physics Editor @LeeBillings for a panel on space junk at #SDGLive during #UNGA. Watch live at 2 PM ET: bit.ly/SDGzone

Black holes! Dark matter! Jostling planets! This story is wild but actually plausible: scientificamerican.com/artic…

Dark Matter Black Holes Could Fly through the Solar System Once a Decade

The universe’s hidden mass may be made of black holes, which could wobble the planets of the solar system when they pass by

As NASA prepares to send astronauts back to the moon, doesn't it seem like it's taken longer, cost more and been so much harder than Apollo? Turns out there are good reasons for that: scientificamerican.com/artic…

Why Is It So Much Harder for NASA to Send People to the Moon Now Than It Was during the Apollo Era?

NASA’s Artemis moon program faces challenges the Apollo missions never did

Happy birthday to astrophysicist and former IOP president, Prof Dame Jocelyn Bell Burnell, who donated her £2.3m Breakthrough Prize to support PhD #physics students from under-represented groups. This year, over £1m has been granted to awardees of the Fund. Read more here: iop.org/about/news/bell-burn…

In quantum mechanics, everything changes when someone makes a measurement. But who counts as "someone"? A human? An AI? This fascinating feature by @anilananth investigates: Can AI Save Schrödinger’s Cat? scientificamerican.com/artic…

Can AI Save Schrödinger’s Cat?

Outcomes in quantum mechanics depend on observations. But must the observer be human?

It was fun recording this with @RachelFeltman & @ClaraMoskowitz. Huddle up, listen in, and get ready for more fantastic podcasts from @Weirdest_Thing & from @sciam. (Also be ready for Rachel to do a flying slam jam elbow drop on @hankgreen & @johngreen off the turnbuckle).
