Pyramids

From Discovery News:

After almost two decades of failed attempts, chances are now strong that researchers will reveal next year what lies behind the secret doors at the heart of Egypt's most magnificent pyramid.

It is amazing to me that something as old as the pyramids, particularly something that has been the subject of so much interest, can still have unexplored areas.

There are days when I get the feeling that there are too few unexplored places left in the world, but if we haven't explored every inch of something the size of a pyramid, what do we have left to discover in something the size of our planet?
