I’m using an LG K9 right now. Works ok, but I’d prefer a smaller screen

But then they don’t use PhD’s preferred pronouns to refer to PhD in the tweet 😔

How do they measure eerieness? What if it’s a reassuring green glow?

I find Wolfram Alpha helpful for this sort of thing. It said

13 TeV ≈ 13 × approximate kinetic energy of a flying mosquito ( ≈ 1.6×10^-7 J )

So absolutely tiny on everyday human scales. Credit to astronomy that they can even detect it over something as large as the earth’s atmosphere.

Oops, I’d assumed that was the total energy delivered to the atmosphere, but it’s the energy per photon, and they detected at least 140 of them (so there were probably a lot more unobserved). Who would have thunk to read the article before commenting?

That’s not known. Relativity predicts that they shrink to an infinitely dense singularity, but we don’t know that relativity is still applicable in that environment. They could shrink to a small but finite volume, or they could stay at uniform density within the sphere of the event horizon (which would make SMBHs less dense than water), or space could just stop at the event horizon and there wouldn’t even be an inside. And all those possibilities would look identical from the outside.

Oof my grouchiness was intended for the headline writer - sorry that you caught some of it. It’s fine enough to read a little blurb about GRBs over morning coffee, and this article for the most part was just that. It’s just a shame today’s journalism needs to cram some sort of angle into everything.

Anything 2 billion lightyears away ain’t going to do diddly squat to life on earth. Now let’s check the article to find what the heck today’s apocalyptic headline is misrepresenting…

Here we go. You remember October 2022 right? When a gamma ray burst seared the atmosphere, and that’s why we all live underground now.

the October 2022 event, known as GRB 221009A, was exceptional, saturating detectors on NASA’s Fermi Gamma-ray Space Telescope and leaving an afterglow at longer visible wavelengths that even amateur astronomers could see for hours.

Your comment got formatted as a numbered list! (At least it did on the client I’m using). I think you can fix it by putting a backslash before the period, like 1992\. But space fans..

U R my number -e^iπ

Same, same.

That’s numberwang!

I know it’s not relevant and nobody cares but those bigger -illion numbers really tick me off. Like, it was once was a perfectly usable system. It was a million to some power. So a quintillion is a 5-illion, is a million to the 5th power, is 10^30. Simple. But then headline writers got a hold of the words billion and trillion to sensationalise about stuff like national budgets, who cares if they’re using the right words for the right numbers, and now the pattern is broken. It’s, what? A thousand times a thousand raised to a power?

So 40 quintillion is … 40 × a thousand × a thousand to the fifth power, is … 4×10^(1+3+15), 4×10^19? Is that right? 40,000,000,000,000,000,000? Why does it have to be so difficult? It’s just numbers.

Keeps going faster, and slower, and faster, and slower

the link doesn’t work? 😅

Lemmy community links are their own special mystery. Try now?

If you ever get close to a human, and human behaviour, you will see real stupidity. It is a kind of bottomless stupidity, a fiendish stupidity. They are the most horrifying, cannibalistic and nightmarish creatures in the world.

The other obvious casting choice

Haha. So, after I posted this, I thought I should crosspost to the Björk community. But there didn’t seem to be one, so I made it. And of course I wanted that video as the first post, so you just saved me a YouTube search.

This is what I found. I guess it’s some sort of limited release that cinemas can request if there’s interest

The film will be trickling into IMAX cinemas across Europe and North America in the coming weeks / months, and may already be playing at a theatre near you. Please contact your local IMAX cinema for more information.
