What would happen if you tried to hit a baseball pitched at 90% the speed of light?

Conclusion? "Everything within roughly a mile of the park is leveled, and a firestorm engulfs the surrounding city. The baseball diamond is now a sizable crater, centered a few hundred feet behind the former location of the backstop. A careful reading of official Major League Baseball Rule 6.08(b) suggests that in this situation, the batter would be considered 'hit by pitch', and would be eligible to advance to first base."

DO WANT

(anyone up for a trip to the Netherlands where we beg, borrow, bribe, or steal these?)

Unfortunately, the supplies involved seem to include a parasailing kite, which nevermind all the engineering involved (these are motorized; he's just controlling the timing of flapping) sounds expensive.

Does really drive home just how big of wings you need on a human-sized body (never mind a dragon) to enable flight in Earth gravity, though.

edit: See also Man Claims to Fly With Custom-Built Bird Wings; Analysis of the Human Birdwings, which discusses whether there's anything in the video saying it must be a fake based on camera motion and some of the physics; and Man Flies Like a Bird Flapping His Own Wings (Update 6) on Gizmodo, which has a bunch of updates with people saying both "OMG fake" and "this is feasible".

This really doesn't look like 3D CGI to me, though it could possibly be a physical rig with cables painted out.

Amazing World of Insect-Wing Color Discovered

Until now, the wing colors of many flies and wasps were dismissed as random iridescence. But they may be as distinctive and marvelous as the much-studied, much-celebrated wings of butterflies and beetles. ... Generations of biologists seem to have missed this partly because they didn’t look for it, and partly because the colors are most evident against a dark background. Against a white background, they’re invisible — which is exactly how most entomologists study transparent wings.

WCI student isolates microbe that lunches on plastic bags

Although my understanding is that even "biodegradable" stuff doesn't decompose all that well in landfills either, because of the way they're packed, but hey, it's something.
