Nifty! That really gives you an idea of the relative sizes and colors of both Earth and Moon. I guess Deep Impact has nothing better to do at the moment, so why not take in the sights?
This is definitely neato-rama. There are all kinds of potential ways to harness ocean energy (waves, wind, tides, thermal gradients), but that's one I hadn't heard of.
Matt is actually right. The only reason the asteroid (and make no mistake, this is an asteroid, not a meteorite) would be glowing initially is if it were cooling from a recent impact. Sloppy job on the part of Discovery Channel or whoever does their CGI, but the point remains that we're well and truly screwed in the unlikely event that something like this happens.
However, nocedhal, it is quite possible for large objects like this to go "unnoticed". We like to think that we've got all the large stuff out there, but they're still finding smaller earth-crossers (~1km) with some regularity that would still cause us a world of hurt.
Furthermore, at the scale of this impact, mountain ranges, ocean floors and other diffraction sources are totally insignificant to the propagating blast wave. It makes a difference when the scale of the object is similar to that of the wave, but not for something this big.
It is certainly *not* possible. Even with modern age-record winners, proving date of birth can be tricky. There's no way someone was three times older than the oldest humans ever proven.
Another bright ray in the gloomy modern world. And another is that, in 50-some comments on this thread, everyone seems okay with this. I'd expected a lot of reactionary homophobia and poorly-spelled name-calling from the resident Neanderthals.
Yes, marriage was originally a religious institution. But it has been thoroughly secularized and thus religious definitions of secular marriage can no longer apply.
Congratulations to George and Brad and all the other couples.
