So here we have a third possibility; a little well known cave.
This doesn't jive with Hawass' contention that there are no
caves at Giza either. Surely it wouldn't be all that complicated
for someone to peek in and see if there's no cave at all, a little

How unlike rocket science can this get. There is great confusion

Caves can exist for millions of years underneath much larger
mountains than the pyramids.
Did the guys who dreamed up ramps in the 1850's check the seismic
record? They've been running wild with a theory for 150 years and
won't even check to see if there's a cave in the TotB.
One of the largest sinkholes in the world is right there in the "Land
of Horus". This wasn't the result of the collapse of a 30' cave.
