The only time I ever see a post from truth social is when it’s a screenshot of one of trump’s messages. I like the idea that he is literally the only person that posts there and the feed is just a list of his ramblings

One more paper from the group out arxiv.org/abs/2508.00062 🎉 Led by Lieke Sippens Groenewegen, who finished her MSc in my group @grappainstitute.bsky.social in February, and with @sanjanacurtis.bsky.social we developed an end-to-end pipeline for kilonova lightcurves and spectra #highenergyastro 🔭🧪

3D full-GR simulations of magnetorotational core-collapse supernovae on GPUs: A systematic study of rotation rates and magnetic fields We present a series of fully three-dimensional, dynamical-spacetime general relativistic magnetohydrodynamics (GRMHD) simulations of core-collapse supernovae (CCSNe) for a progenitor of zero-age-main-...

To kick off here on bluesky I wanted to share some recent work from the group. First off arxiv.org/abs/2504.11537, the first science paper produced with our new GPU-accelerated GRMHD code GRaM-X.

An NES cartridge with a label that reads "The Old SwitchAroo" and "Blast Corps" with an illustration of two robots from Blast Corps and one remote controlled car. The additional text below the label reads "-or- I've Heard of a Crash Course, but this is ridiculous" and the text to the side reads "with Nate Brown"

In the newest episode of The Old SwitchAroo, Nate Brown (NateBlackest on Twitch) joins us for Blast Corps, the 1997 action-destruction game for the Nintendo 64.

AAS Journal Author Series: Amber Young on 2024PSJ.....5....7Y

Amber Young (Northern Arizona University, NASA Goddard Space Flight Center) chats about her article on Earthlike exoplanets.

I had this exact same thought when I saw it

Exoplanet discovery database, ExoFOP, reaches 1 million files and counting Discovering an exoplanet doesn’t mean having one, definitive eureka moment. Instead, it requires multiple observations, sometimes from multiple observatories, and the scientific community coming toget...

Some fun news to interleave in your TLs - the Exoplanet Follow-up Observing Program is an open sandbox for the astronomy community to collaborate on confirming and characterizing planets. It's totally voluntary, but apparently, if you build it, they will come!

"Why should my tax dollars go to fund your astrophysics research?" A thread. 🔭🧪

Brushing aside how absurdly little of the federal budget goes to science (according to the Planetary Society NASA accounts for only 0.3% of federal spending), the benefits of funding astronomy fall into two camps. (1/n)

Absolutely the route. A very common question here (maybe elsewhere too) when people get together is “so, which way’d you come?”. It’s almost like an ice breaker

Protecting American Energy From State Overreach By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered: Section 1.  Purpose.

Does anyone know if this EO furthers Yarvin’s plans? Is it increased isolationism or is it just unrelated?

www.whitehouse.gov/presidential...

Snippet from the latest executive order on domestic energy production reading: “For example, when States target or discriminate against out-of-State energy producers by imposing significant barriers to interstate and international trade, American energy suffers…”

I feel like the new EO has a lesson about tariffs

WHAT YOU NEED TO KNOW ABOUT TRUMP’S TARIFFS The quick version. On April 2, Trump announced sweeping tariffs on every country except Russia, North Korea, Cuba, and Belarus. Tariffs are a tax that are paid by the importer when goods enter our country. Prices on everyday items will increase radically and responsive tariffs will harm US businesses. Ask your federal representatives (numbers at reps.fyi) to revoke Trump’s ability to apply tariffs. Who pays tariffs? The country of origin does not pay tariffs. Whoever is importing the goods in the US pays the tariff, and passes the cost along to regular consumers—in other words, we, the people will pay the tariff. How did Trump calculate his tariffs? Trump’s tariff sheet claims that countries charge the US exorbitant tariffs. This is a lie. The number he lists has nothing to do with tariffs, but is instead a trade deficit ratio, calculated as the dollar amount we import from that country divided by the amount we export to that country. What is the difference between a trade deficit and a tariff? Trade deficits are not tariffs. We buy more from some countries than they buy from us because many Americans have disposable income and purchasing power. It is not possible, or beneficial, for countries to have perfectly balanced imports and exports. What impact will this have on your life? You will pay more for everything you buy, and American businesses will lose overseas customers. The last time America passed sweeping tariffs was in 1930; this is part of what made the Great Depression last so long. Trump’s tariffs are higher than the failed 1930 tariffs. Who is responsible? • Donald Trump and his cabinet for imposing the tariffs. • Every Senator and Representative who fails to block Trump’s tariffs. What can you do?

• Contact your Senators and Representative (info at http://reps.fyi), and ask them to revoke the so-called national emergency that Trump is using to impose these tariffs. • Distribute this fact sheet so that people know who is responsible and how to join in. • Join a protest against Trump’s damaging policies. Sources for these claims & this sheet itself can be freely downloaded at TrumpsTariffsExplained.com

I've finished my extremely basic normie tariff discussion. Here's what it looks like.

I agree with everything you say, except that I didn’t give a definition of caring. I just said not posting isn’t not caring, and not posting also doesn’t mean no action

I have an admittedly very small network, but I’ve never heard anyone say posting about Palestine is worthless

Retaliation from tr*mp is one obvious reason (and that of all the big scicomm accounts you singled out an immigrant woc is why I posted), but there are likely more.

I agree it’s a deliberate choice, but you have no idea what’s happening in the vast majority of their lives. Have you asked any of them why they haven’t shared these posts?
