What a momentous occasion. Been reading these book for 15 years, now in a few months it will all be over. I'm getting quite emotional :S

A few quick corrections...

Big Crunch (And thus Oscilating Universe theory) has been largely disproved to be possible in our universe. Galaxies are all accelerating, not slowly decelerating.

Pyramids have been largely explained, nothing too mysterious ther.

Stonehenge was found in the 19th century, entirely fallen down. It was re-assembled in it's current position assuming that it was intended as solstice shrine using modern technology (And maths). Nothing mystical there.
