I remember this being talked about >20 years ago when the idea came up and they had to get clearance from the Egyptian gov which were not keen on the idea. If this is indeed the same "hidden passage" ... Gee .. 20 years to get clearance.

Just when you think Egyptology can't get more interesting, it does. No wonder "just a quick search about the Pyramids" turns into a lifelong obsession for many.
The Nature paper from last year: <a href="https://www.nature.com/articles/s41598-025-91115-8" rel="nofollow">https://www.nature.com/articles/s41598-025-91115-8</a>
What's exciting about this is the opportunity to examine an untouched area of history. Sadly, over hundreds of years, much of the artifacts from these sites were looted. Hopefully we've learned our lessons at this point and can preserve them this round.
Although from the photos of the space, it looks to be empty, so no amazing artifacts to be discovered. I would guess that any ancient unknown artifacts that are discovered in the next century will come from undersea archaeology with all the limitations that exist for finding things that have been underwater for thousands of years.
I sometimes wonder what digital historians will rediscover about our current era internet in 1000 years.
They're going to assume our entire society was built around /r/datahoarders (because that's all they'll ever find).<p>Would be fun to write a short story about it. I'm thinking a crossover between <i>Motel of the Mysteries</i> and <i>Galaxy Quest</i> and such.
We'd be exploring earth then like we are exploring mars now and someone akin to Elon would be making statements like "Occupy Earth".
They'll find whatever they need to find (or not find) just as we do. Its simply an impossible exercise to go back in time, carrying all of our assumptions about modern life and what we have been taught about the 'Ancient world'.
Who knows what the aliens left behind!
Are we able to generate muons outside of a particle accelerator, or does all muography rely on cosmic rays?
It's pretty much just cosmic rays. I suppose you can sort of create them by using an accelerator to generate a beam of the appropriate particles that'll hit a target or decay and become a beam of muons outside the accelerator but that's not really all that practical. Incidentally, this is how neutrino beams are generated.
<a href="https://en.wikipedia.org/wiki/Muon_tomography" rel="nofollow">https://en.wikipedia.org/wiki/Muon_tomography</a>:<p><i>“Muon tomography or muography is a technique that uses cosmic ray muons to generate two or three-dimensional images of volumes using information contained in the Coulomb scattering of the muons.<p>[…]<p>Since 2010s researchers are also exploring and attempting to use artificially generated muons—created by conventional accelerators or laser-plasma systems—for muon tomography.”</i><p>I may overlook something, but skimming the references, I get the impression the latter still is an idea. References are about simulating the machinery, discussing requirements of hypothetical machines, etc.
Muons are not stable, thus you cannot tear them off matter as you'd do with electrons. And they have a mass of 105 MeV each, which means you need a nice particle accelerator to create a few of them.<p>Furthermore, if you want (most of) them to fly in a particular direction, you need to scale that accelerator up.
another clickbait title<p>room was revealed and photographed with endoscope in 2023, nothing new happened since<p>it's not even "passage" - just a room
