Yes, we are made of stardust. But so is garbage.

We crossed the borders from Netherlands to Belgium to Luxemburg to France today with only the road signs making us aware that there is the (imaginary, human-made) border at all.

I don't want to live, again, in a world where there are more borders.

Eine absolute Leseempfehlung: "Die Katze des Rabbiners" von Joann Sfar.

Unglaublich tiefgründig, unglaublich witzig, unglaublich berührend.

Ich habe spätestens auf Seite 25 gewusst, dass es ein fünf Sterne Buch sein wird - und der Rest hat nicht nur nicht enttäuscht, sondern sogar mehr geliefert als erwartet.

@TeaKayB @TalesFromTheArmchair eeeeeh - most things out there in the Universe, even the very high energy ones, don't have enough energy to create black holes. You'd need to get pretty close to the Planck energy (assuming spacetime does not have extra dimensions which we so far seen no evidence of) and there are no known processes that can bring stuff there.

@TeaKayB @TalesFromTheArmchair in today's universe: yes! Possible totally absolute fringe cases notwithstanding.

@TeaKayB @TalesFromTheArmchair Excellent question! No, definitely not. Not even in the big natural space-accelerators such as supernovae etc.

The world is what it is - but there are flowers.

Welcome to the tulip extravaganza.

No, covid did not teach me that online conferences are just not working. It taught me that 2/3rds of all conferences could be fully online (though one still needs to think about best structure for them and not just transplant them without any adaptation) - and the remaining third needs to focus even more on interaction (unconferences, small workshops, hackatons...) and not the usual talks.

Royal Alcázar of Seville

(I'm absolutely in love with Mudéjar architecture but there seem to be no books on it except in Spanish 😢 If you know any in English or German, recs welcome.)

Córdoba at sunset.

[My phone camera seems to be dying (and it bugs me that I don't understand how the particular CCD artefacts I see come to be), so not sure how long I'll be able to provide these, but let's try as long as it works.]

It's both impressive (I got a good nose for stuff like this by now) and scary (I did have to develop the nose and also yeah, those people are here) how often I read a single thing comment, think "this sounds like someone denies Soviet atrocities" or "this sounds antisemitic" or "sounds like far right stuff", check the profile of the commenter and lo and behold, there is a Stalin (and often also Putin) apologist, antisemite or a nazi there.

I'm thinking about what to do with this place and how to use it productively. And the best, most useful thing I get out of it is the happiness of shared books and recipes and the chance to meet new great people.

So what I will try is to make it a happy and productive space for us for the next months. I will not always succeed but we need it.

@goatsarah when things get very small, so when things get close to singularity, we need to use both General Relativity and quantum mechanics, however so far we do not know how to combine both. Finding this "Quantum theory of gravity" or "Theory of Everything" is one of the big questions of today's physics! So a singularity is a handy description within the general relativity but we know that general relativity is (likely) not enough...

What did you always wonder about #BlackHoles? Something that you always wanted to ask an astronomer working on them?

Collecting questions for a reason, maybe even answering them in the comments (or at a later point).

Let's focus on happy things we need to refuel: What are you reading this weekend?

Here, it's classic Scandinavian crime fiction (Martin Beck series). Not sure what the second book will be once I finish this one.
