Tunguska Explosion
Feb 18 2009, 2:24 PM EST
Again, a classic mystery, this time Russian Siberia in the early 20th century. Was it a black hole that struck the earth and kept on going but didn't come out on the other side? Was it an unidentified aerial phenomenon? A meteor? A fragment of a comet? Has anyone been up there lately with a geiger counter and other modern equipment?
Do you find this valuable?
