Last week, I watched a YouTube video about this, and honestly, the conclusions were a bit over the top. I can't find it now, but you could see the ground-penetrating radar images and these reconstructions—it was pretty ridiculous, to say the least.

Professor Lawrence Conyers, a radar expert at the University of Denver who focuses on archaeology, told DailyMail.com that it is not possible for the technology to penetrate that deeply into the ground, making the idea of an underground city 'a huge exaggeration.'

Saw this on Twitter yesterday.

There was always that thing about the tunnel that wemt through the sphynx's head.
They were always truing to cover that up.
Now there are mysterious shafts?

This news has been in my news feed the last week or so.

My question is why did it take so long to find? Surely scientists have been studying the pyramids for over 100 years. No one looked underneath?
