Spaghettification, sure — but if the black hole is rotating, shouldn’t we consider the possibility of rotinification / fusillification? ⚫️🔁🤔

I feel like keeping the jump at a constant 2 seconds makes it too easy for folks. May I suggest that the interval change gradually over the course of the year (i.e. fractions of seconds)? 🙃

Challenge! Daylight Time "solutions," but each one has to be worse than the one before. I'll start: Instead of a one-hour switch twice a year, how about 4 forward jumps of 15 min each, at one-week intervals, in the spring, and 4 backward jumps of 15 min each, at one-week intervals, in the fall. 🙃

Meet three scientists who said no to Epstein The warning signs included a web search, a mother’s doubts, and inklings of a “sexist attitude”

Many of the scientists Jeffrey Epstein courted were already well-established and well-funded. So why didn’t they all just say no? Science talked with three who did just that.

Here’s how Epstein approached them, and why they refused to have anything to do with him. ⬇️ https://scim.ag/40qbXnv

Oh, I'm sure you're not alone. (When I did a very informal survey on the old site some years back, it seemed there was roughly an even 3-way split between year-long ST, year-long DT, and the status quo.)
