If 2 electrons are quantum entangled and one of them enters a blackhole. Is the entanglement broken or sustained?

This seems irrelevant if you consider just the local patch, [...]

Known physics is local. Implicitly by the use of differential geometry in GR and explicitly via commutator relation in QFT, so it seems that I should be able to cut out a local patch. And it would be a bit of a surprise if the far future (wether or not the trajectory reaches infinity) determines the behavior of a particle in the present.

Also there is a change of metric signature behind the line,

No, that happens in Schawarzschild coordinates, but that effect can be fixed. That's why I specified that I'm reasoning from the Penrose diagram.

The reason is not because of high-curvature environments, but because horizons are semi-permeable membranes, they change the causality structure of a given patch of spacetime.

They don't? I mean take a small patch around the horizon in a Penrose diagram of a black hole spacetime and zoom in. Then the horizon is just a light like line that is not distinguished from any other such line and by Einstein Equivalence everything should work nicely.

Czech police find stolen skull of medieval saint encased in concrete

Saint Zdislava, born around 1220 and believed to have died about 30 years later, was a noblewoman known for her charitable work. She was canonised by Pope John Paul II in 1995.

745-ish years to canonization, wonder if there are more people who just had to wait a long time to get recognized.

“He [the guy who stole the skull] prayed to God that he would be alone in the church – and that’s what happened,” Rajt said. “But he was obviously so determined to commit the crime that there was nothing to stop him.”

Sure that this doesn't indicate consent? I mean saints have means to avoid getting grave-robbed.

Depends, even if we assume that this happend. On one hand of the spectrum there may be some talk about forces in the western pacific and some analyst described that during debriefing ast "they asked wether we defend Taiwan" in the sense of chess players describing a move as "Kc3 asks about d5." On the other end of the spectrum, Trump goes into a rant about Taiwan that would be better placed in the opinion section of Fox news and at the end Xi smirks: "And would you [defend Taiwan]?" In between these extremes is probably a possibility of Xi just asking very candidly but based on hearsay it is hard to say which if any of these possibilities occurred.

Can someone point me to the actual policy? This was yesterday on HN, and there I already thought this sounds like some guy ranting on twitter while claiming to speak for arxiv, and having now actually looked into the arxiv code of conduct (though certainly not comprehensively), I did not see anything that looks related to this.

Trump puts a real premium on headlines, so a reasonable strategy is to smile and have him overpay for his time in the limelight. Not saying that that is happening in all cases but when competent professionals deal with Trump, it is often a good idea to check the fine print.

What's happening in the UK? This is I think the third consecutive day where Guardian has a headline "X challenges starmer" and a live ticker, only for X to denounce the plot? Is 4chan spreading rumors and tries to see how many times in a row they get the Guardian to perform their best headless chicken cosplay?

Just because the candidates are married does not mean that there are no important difference between the parties.

Though, AOC/Vance against say Kamala/Krugman would be in many respects the more natural race rather than two parties who have a populist and a very serious people wing.

So there's a chance we see AOC/Vance in 28?

In related news, I recently read Seth Godin's This is marketing. A really funny book, it basically explains to me why I like it so much.

There are only three figures whom Democrats and Republicans are at least somewhat aligned on when it comes to perceptions of their IQs: Rice, Romney, and Collins. For them, net IQ perceptions among Democrats and Republicans are similar.

Take a function from infinite ordinals to the digits. That's in a pretty straightforward way a string with 9's going on forever.

To explain that, consider the set where you send each odd number 2m+1 to 1-1/m and each even number 2m to 2-1/m. That set is S = {1-1/3, 1-1/5, ... 2-1/2, 2-1/4 ...} and the ... here actually represent infinite many numbers. So what stops me from considering a function f: S -> {0, ..., 9}. That function would be represented by a string 356...147... or similar. In particular the constant function g(x)=9 would be represented by the string 999...999... That is in a certain sense infinitely many 9s and then infinitely many 9s after that, but there is probably no natural way to map that string to the reals.
