An explosion on the Moon

I don't know Joe, but his definition would encompass things like gunshots and car crashes that are definitively NOT explosions.

Then you must not have read his definition before you posted it.

Using your own post #80 against you again, "There is no fixed definition of an explosion."

But look at Wikipedia: "An explosion is a sudden increase in volume and release of energy in a violent manner, usually with the generation of high temperatures and the release of gases."

Nothing there about it being stored energy. The above definition includes an electrical explosion - not from stored energy.

I am starting to understand your own narrow and personal definition of the word as stored chemical energy or pressure that is suddenly released. But then why is a gunshot not an explosion?

It took her a while to get there, but we finally found out what happened to Alice Cramden.

Slight correction:

It took her a while to get there, but we finally found out what happened to Amelia Earhardt

Don't buy that one?

How about Judge Crater (thats actually a good one. Crater, get it?)?

Jimmy Hoffa?

Al Gore's lock box?

OK. Your's was better, except for the fact that there is no way Ralph would have EVER actually hit Alice. He may have been an unrepentant male chauvinist pig but, he was a chivalrous unrepentant male chauvinist pig. He would never have touched her and she knew it. End of story.

I've actually been thinking about this whole topic today, as crazy as that sounds (no comments from the peanut gallery). I watched The Quiet Man as part of the Christmas (???) John Wayne marathon on cable today. Talk about un-PC!!! But you know he would rather die than hurt her.

We live in a different age.

Since a meteor is an atmospheric phenomenon, should the term be applied to the airless moon?

I think the correct term for a such an object striking the Moon is "meteroid."

Sounds vaguely French.

I was just getting ready to say the left will soon be blaming this on "lunar warming", caused by Bush and greedy capitalists (of course).

I think it's more like 5 inches, and it would have at least picked up the net gravitational energy difference between the surface of the Moon and the top of Earth's atmosphere, a piece.

The two guys standing beside the flag on the LEM have had extensive experience with the criminal justice system

The guy on the extreme left has some political leanings, and is married to Barbra Streisand

Seriously, it shows that there is still room for amateurs in astronomy. It would be worth someone's time to keep an eye on the Moon during meteor showers, to see if they could spot another strike.

Apollos, Atens, and Amors are the NEA families currently known, with about 500 known I think, plus another 1700+ which are still having their orbits analyzed. It is likely that one of these families of NEAs struck the Earth 65 million years ago, extinctifying (I just coined that) the dinos. Given the number of potential encounters, probably all, or nearly all, the catastrophic impacts (such as the one that formed the Ries Basin in Germany, the Haughton astrobleme in the Canadian Arctic, the Tunguska event) result from encounters with these NEAs.

When it first went on in 1975 the end of the century seemed so far away.

The end of the century is STILL so far away.............
