I love the sound of rolling out a thin carpet on top of a shelf.

I read about this from Kip Thorne, but it was his "Black Holes and Time Warps," which was assigned reading when I took freshman astronomy in 1997. Careful with your "looooong time ago," scamp.
The idea is that you make a wormhole whose two mobile ends are initially near each other in spacetime. 1/

Schlieren imaging really feels like magic. You do some fiddly adjustments with a lamp and a camera together right at the focus of a curved mirror, and suddenly the fiddliness becomes sensitive to tiny variations in the air density near the mirror itself.

I really enjoyed this colloquium-style talk 🔭 about the origin of the Chixulub impactor — a carbonaceous chondrite which must have formed in the outer solar system, beyond the "snow line," and then scattered into an Earth-crossing orbit.

Everybody's favorite extremophile, the tardigrade, is sometimes also called the "moss piglet" because supposedly that's where you can find them in your yard.
Now we have learned about an extremophile moss, so future space tardigrades can have a place to come home to!

Is it an anachronism to put this kind of acrostic into Chaucer's mouth? My understanding is that acronyms are (more or less) a twentieth-century development. But there are acrostic poems going back to antiquity.

A video about how "high sodium is bad for you" and it's a chemistry nerd using sodium metal to set water on fire
I keep seeing videos that are like "THE SHOCKING TRUTH ABOUT/YOU DON'T WANT TO EAT/THIS IS WHERE IT REALLY COMES FROM" about food and i dont know how to explain to people the concept of "cooking is a transformational process that turns one thing into another"

Apparently tsunamis displace enough air to distort the ionosphere. This past summer, such distortion was used in real time to monitor the evolution of the tsunami from the Kamchatka earthquake.
A striking example of how interconnected the system is:
A tsunami created ripples high in the atmosphere...

'It sounded kind of crazy': How ripples in the high atmosphere warned scientists of a tsunami in real time
Tsunamis are notoriously difficult to spot on the open ocean as they race towards shore. But in the summer of 2025, scientists watched one unfold as it happened.
