['Civ note:] The paper was a smoking hot pile of BS from day one, but it attracted a lot of attention. The overdue retraction was a whole month ago, and this is the first I've heard of it. Glad that stupidity is now over. Fringe online sources cover this as if it has anything to do with the ScanPyramids project, which it does NOT. Why? As Peanuts character Lucy VanPelt once said, "have you ruled out stupidity?". Next up, I'm sure, will be how these findings have been suppressed by 'them', and that 'they' don't want you to know about.

I'm glad that's over.

An entertaining expression of opinion.

George Noory is disappoint.

[Merrick]

I’m shocked!

Except of course for the fact that I called this out as complete BS 3-4 years ago when everyone was losing their minds over this.

ALIENS!!!

If there’s no internal chamber, then where do they keep the saucers?

[bk1000]

Why can’t we do proper exploration on those sites?
Are they afraid they will find Jewish artifacts older than the Arab artifacts?
What could be the reason?

[TheThirdRuffian]

“ where do they keep the saucers?”

Next to the cups, of course. Duh.
