Call in sick, take the day off, quit your job if you have to... Today, Sir David Attenborough takes us through a fascinating journey, exploring the last great frontier on Earth: Caves.Filled with unbelievable footage, and to the sound of a beautiful musical score, this episode will acquaint you with a world full of exotic life forms and amazing geological formations, including the world's greatest concentration of crystals. Some of these caves are so large that not only could jumbo planes fly through them, they could easily engulf the Empire State Building!
Watch out for the amazing optical illusions that form when fresh water meets with salt water; it's truly mesmerizing...

I find the sulfuric cave mollies particularly incredible: an amazing feat of evolution and proof that life can exist in an environment that is relatively inhospitable to us common animals. Take that creationists!!
ReplyDeleteYou know, it's always struck me as a bit naive and narrow-minded when astrobiologists assume that the conditions for the possibility of life in the rest of the universe should resemble those with which we are familiar here on the shallow surface of the planet.
ReplyDeleteWater? Other liquids may work just as well...
Photosynthesis? Chemosynthesis can do just fine on its own...
Carbon-based? It's not the only social element, you know?
That also kind of makes you wonder whether we would even be able to recognize many life forms were we to actually run into them, doesn't it?
