But this sweet, slightly unsettling song, with a video like a fragment of a Lynchian dream, was one of my instant favourites.
hi ho, hi ho, into the canyon we go
the ruts in the road won’t guide us back home

I’m enjoying They Might Be Giants’ new album “The World is to Dig”, though it’s a mixture of tracks I can take in after just one casual listen, and others where I need to sit down and read the lyrics from the song sheet and follow every word.
… discussing this with you if you’re simply convinced that you’re right and everyone else, including people like Thorne and Hawking who spent a lifetime on this subject, is mistaken.
If you’re serious about any of this, submit it for peer review, and actually listen to the feedback you get from people who have thought hard about these issues.
I have read what you’ve written, and I think that you’re confused about the implications, but there is no point in me or anyone else …
… try to have your claims properly assessed. If you just keep saying that everyone who has studied and thought hard about these things diligently for the last 60 years is just blind or stupid, no one will have any reason to take your arguments seriously.
Now, you have no reason to care what interpretation I put on these well-known facts that is different from the interpretation you put on them. I don’t have a PhD in physics, let alone one specifically in GR.
But that is why posting breathless claims on social media is a really unfortunate way to…
they will measure/observe each other moving separately at well-defined distances throughout the process. The fact that these distances are specific to these observers doesn’t render them irrelevant.
I plot some detailed results here:

Having a metric interval of zero between events does not make them “coincident”, just because there is no coordinate-independent spatial or temporal interval between them.
For example, it is an unambiguous prediction of GR that if a train of observers fall from the same point at successive times,
You are making way too much of the metric interval being zero between different things falling through the event horizon. This has been understood perfectly well ever since people started taking the Schwarzschild solution seriously; nobody has “missed this” for about 60 years.
But having read your paper now I suspect that the conclusions you draw from this are not shared by most experts in the subject.
As a non-expert, myself, I won’t attempt to address that. I hope you can have a productive discussion with the referees when it undergoes peer review.
I posted the link because @zygolatryfoe.bsky.social mentioned it, but had forgotten the details.
It’s uncontroversial that the metric interval between events where successive infalling bodies cross the horizon is zero, and there is no invariant notion of spatial or temporal separation between them.
Doing a word puzzle with a relative yesterday:
They: Ruth.
Me: That’s not a word!
They: You can be ruthless, so …
Me: That makes sense, but English is not that logical!
Concise dictionary: No “ruth”.
Complete dictionary: Archaic now, but yes, “ruth”: a feeling of pity, distress, or grief.
Our new album is out today! A sincere request to help spread the word!
The whole essay is a great take-down of the hype about AI spontaneously generating its own goals and interests.

This is hilarious! Amanda Gefter wanted to ask Yuval Noah Harari why he misrepresented the story of a chatbot hiring a TaskRabbit to get past a Captcha, but she couldn’t get past the Captcha on his web site … and nor could the TaskRabbit she hired to do it for her.

Our paper on detecting terraformed planets is finally published: doi.org/10.3847/1538...
Context: we wanted a method to detect life in the universe that does not depend on any particular chemistry or hyperspecific definitions of life

This is a great article — worth savouring not skimming — packed with human and scientific drama as it delves into the history of this idea going back to a 1964 thesis by Sjur Refsdal. Fifty years later, the first supernova used in this way was named SN Refsdal.
It’s astonishing that we can (sometimes) see the same supernova *billions* of light years away along multiple gravitationally-lensed paths that produce time differences on the human scale of 10 years or so.
www.science.org/content/arti...
Multiple lensed images of supernovae help pin down the Hubble constant:
“If SN Requiem reappears this year, it will lead to a higher value of the Hubble constant and validate the astronomers’ camp. If the supernova is not seen until next year, it will lead to a lower value…”

“My patient is refusing a drug studied in 170,000 people because of side effects that a 124,000-person analysis just confirmed do not exist — while injecting a compound studied in 14 humans, from unregulated sources, based on the recommendation of someone who profits from selling it.”
I haven’t eaten liquorice for ages, but when I read “You should not eat large amounts of liquorice while taking this medication” …
(a) I had a sudden craving for liquorice
(b) it turns out probably *no one* should eat *large* amounts:

In 3D Euclidean space, the surface equidistant from a point is a sphere, with constant curvature.
In (2+1)-dimensional Minkowski spacetime, the equidistant surface is a (1+1)-dimensional de Sitter spacetime, which also has constant curvature.
