What mysteries remain.

After finding out the Felt guy is "Deep Throat", it had me thinking what mysteries remain.

Here are a few:
1. What was on the erased Watergate tape (about 19 minutes)?
2. What happened to D.B. Cooper?
3. Did Oswald act alone?
4. Who revealed the CIA operative in 2003 (Valerie Plame) to Robert Novak?
5. What really happened to Jimmy Hoffa?
6. What happened to Ameila Earhhart in the Pacific (1937 world trip attempt)?
7. Who killed Chandra Levy?
8. Does the light really go out when you shut the door on the refrigerator?
9. What causes the inital release of a gamma ray burst?
10. What is really at Area 51?
11. Are UFOs real?
12. In some cases why does hot water freeze faster than cool water?
13. Is Einstein wrong?
14. What do cats think people are (I think bigger cats)?

To discuss the unexplained a good site is the Unexplained Mysteries site at

Everything in "Star Wars" that remained a mystery was pretty much explained in the last movie. If I am wrong, put a comment in!

There are supposedly a bunch of remaining mysteries in quantum mechanics. Since I don't understand quantum mechanics, that's all I have to say on that.

Blah Blah Blah Blah... on through the unexplained.
