I am completely obsessed with wormholes right now. Weird, yes. However, the subject is soooooo intriguing, I became obsessed after watching a History Channel Special.
Last night. when Adam and I were laying in bed about to fall asleep, I said "Do you know what a worm hole is?" . LOL. and then randomly spaced about 7 minutes apart so that he couldn't fall asleep I piped up with all these random facts about wormholes. Anyway, you should check it out it's really quite interesting:
