Egypt's main pyramid sites in Giza are accessible to the general public every day, all year long. Although you can go inside the Great Pyramid of Khufu when you visit, one of the smaller two pyramids usually is closed for restoration work. To further complicate your tourist plans, at the time of publication, only 300 tickets are sold per pyramid, per day. You must arrive early to secure your visit inside

I've also read that given the economic instability in Cairo, it's just a royal PITA to visit. Tourists get aggressively hassled to buy stuff, camel rides, tours, etc. I've been to New Grange and Stonehenge. While it's pretty neat to go there, it's just a structure. The real value and interest for me is reading up on what the researchers have found out. Let the plinths for Stonehendge were quarried 150 miles away in w…

Yeah... I've been there shortly after arab spring when there was next to one there. Camel ride people tried to steal from me, had to tell them I was going straight to the tourist police over there before they gave me back the extra money they took straight from my hands...

Here's a different take on all this: http://ajitvadakayil.blogspot.in/2010/12/secrets-of-egyptian... http://ajitvadakayil.blogspot.in/2016/10/eight-sided-pyramid...

Er, not sure if your post is a joke, but if not, that site is a crazy smorgasbord of crackpot theories that is so nutty that I'm not sure that the site even takes itself seriously.

Interesting how the pyramids have been around for 4500 years and we still don't know all about their structure... Fun fact: there's a Neolithic site in Ireland, Newgrange, that's actually older than the pyramids. Fascinating and worth a visit: https://en.wikipedia.org/wiki/Newgrange

Imagine if they find an opened chamber, and that it contains artefacts that can be carbon-dated, and they turn out to be thousands of years older than conventional Egyptology expects.

(I expect there will be artefacts, and I expect their dates will coincide with what we already expect, but I’m always holding out for ”new science” that needs to be explained.)

Nothing blows my mind more than Göbekli Tepe, especially its age. https://en.m.wikipedia.org/wiki/Göbekli_Tepe

Yes I visited it in 2012 and spoke with the German archaeologist who found it, Claus Schmidt. Amazing place and an amazing man, sorely missed.

Slightly off-topic but perhaps someone has an answer: After finishing "Dark Forest" / "Death’s End" I somehow ended up with the questions if our way of doing archaeology is actually a good idea. Currently we i) remove a lot of things from the ground / graves / ruins, ii) analyze them, iii) put them in a museum and iv) write books about them. This means that all the knowledge about those artifacts and our history is s…

why not make long term digital storage for things like this? I would donate for a project like this.

Does HN have any domain experts that can comment on how reliable this research is? I got super excited about the Queen Nefertiti / King Tut secret chamber theory a year or two back (which used similar methods, it seemed), and was really disappointed when it turned out to be all wrong...

Co-author here.

This is not the same method at all and this is much more reliable. For King Tut, they used ground penetration radar, which is very hard to interpret. Here: (1) this is confirmed by 3 independent teams using 3 different detection technologies, (2) we used the same statistical criteria as for discoveries in particle physics (deviation 5 sigma from the model).

In addition, we clearly see the new void on Nagoya's data (Fig.2).

Unfortunately, cosmic-ray muons cannot be used in King Tut tomb because we can only see "above us" (the muons come from the sky).

You could put in an orbit that would have a predefined reentry in the future. Design the satellite to survive reentry and somehow safely land in a way that relies on a mechanical system that wouldn't degrade like electronics in space would.

> You could put in an orbit that would have a predefined reentry in the future. it isn't clear what you mean by this, but there's no picking where something will reenter hundreds of years in the future. if you just want to ensure that it will reenter, sooner or later, that's easily done. > Design the satellite to survive reentry and somehow safely land in a way that relies on a mechanical system that wouldn't degrade…

Well, you could schedule a deorbit burn, assuming the hardware is still in working order far into the future.

> There are distinctions to quibble about, sure That's an example of stuff in the middle of a whole bunch of other stuff, not in the middle of a bunch of non-stuff. I'm not sure that it's all that similar at all, beyond as a a very general "finding stuff can be hard" example.

Oh, I may have become confused as to which part of this thread I was responding to - I thought we were talking about finding a satellite after reentry.

Oh, I imagine unplanned and reentry would likely make it very hard to locate, if not destroy the contents in the process. Decaying orbits would mean it's likely to happen, too. But I think if a civilization has the capability to reach an orbit, it's likely they have the technology to find something in orbit, or will shortly.

A better plan might be to create a structure on the moon to house it, and create giant triangles in the landscape of the moon visible through telescope that point towards it. The moon is fairly stable to my knowledge (except for meteorites, but I think that can be somewhat mitigated depending on the time frame we are talking about), and people always like looking at the moon through telescopes...

This diagram shows a shaft going into this void from two sides. I was wondering why they don't send a robot down into those. Seems the answer is that they have, but there's something blocking the shaft and they're not willing to destroy it any further for some reason: http://guardians.net/hawass/articles/news_on_the_robot_Dec_2... http://www.crystalinks.com/gantenbrink.html http://www.gizapower.com/Articles/door2.htm…

"...for some reason:" - they shouldn't be allowed to destroy such an important monument to satisfy their curiosity.
