6 months until the US enforces a no-fly zone over Ukraine so Rafales and F-35s stop shooting down Su-34s

Oops! All PSF!

The community manager was also probably trying to sleep, so rude from that earthquake to wake us up like this.

When you want to make clear you’re blaming the Jews for it, not the Romans.

I just found out about hobby farms and are you people all right. All of human history is about escaping agricultural labor and some people do it for fun????

HCQ as a COVID cure was a 7.5, FTL neutrinos a 5.3, this is fun

Bad science communication can be disastrous. But a typo clearly isn't as bad as fraud. Clearly, a scale is needed to resolve this ambiguity. Thus, I here propose the Loeb Scale for scientific PR disasters. It is NOT to be confused with the recently proposed Loeb Scale for interstellar objects. 🔭

I miss machine learning as the buzzword. It promised less

You know, I would be very interested in reading the Scott Wiener theory of accumulating political capital and using it.

Gib maps pls.

Any surrender would be futile. Resistance is our only option.

I love the positive version of America. The one that strives to be better. Because America today is a hell of a better place than it was in 1620 or 1776 or 1865 or 1945.

Thinking of that professor I know who moved from U of Florida to A&M because he didn’t like the departmental politics there.

Actually the continued sharpness of Einasto, Silk (born 1942), and Peebles (1935) proves that working on dark matter is the key to longevity. ☄️

A new study by scientists at @oskarkleincentre.bsky.social & @fysinfo.bsky.social have developed an AI-powered method to build a digital twin of the Universe—reconstructing its early state and simulating its entire evolution up to the galaxies we see today. www.okc.albanova.se/news/leverag...

Question for the astronomers here: How likely is it, given the known neutron star populations, that LIGO’s o4 completed and we still have detected only one Binary Neutron Star merger? ☄️

I'm sad to report that Rainer (Rai) Weiss passed away yesterday at age 92. Rai developed the design for LIGO, he and Kip got it funded, trained countless researchers, and received the 2017 Nobel Prize. Rai always had time for students and treated us as equals. May his memory be a blessing

As a UC employee, I would encourage anyone at the DoJ involved in that complaint to go take a hike in the Pacific with it.

Hear me out fellow scientists 🧪:

Thanks everyone looping me in on the Sean Duffy thing. Short response to various questions 1) Nuclear power for the Moon is not new. Look up e.g. Kilopower. 2) None of this clearly would violate international law. 3) It can be done very safely, and I suspect NASA would do it safely.

Hear me out: a movie where a vampire kidnaps Liam Neeson’s granddaughter and he must retrieve her. It’s called Staken.

100kW? Oh you mean 250m2/one tennis court worth of solar panels?

I put that image in a talk at some point to replace an Avi Loeb joke because I thought it was mean.

The flight I rebooked on due to a six hour delay on the original, which ended up leaving around 2am, is now 8 hours late. Thanks United Airlines! I love losing 24 hours for this!
