The Sky Is Falling

Close your eyes and see the sky is falling: Josh Homme.

The sky was indeed falling through the immense (worlds largest made from blocks of stone) dome of The Pantheon.

It is highly likely that it could not be built to such spherical perfection in the modern day.
(using the giant blocks of stone...none of your prefab nonsense)

At least we can sit and waste our time looking at photographs on the Internet...woops.
