It's pretty new. The pages come out on Tuesdays, and there are only 2 of 'em... so I'd guess the site's only been online for 9 days. :)

Well, that explains it then! (I did notice that after I commented, but... yeah.)

Well, what a coincidence. It's mine now, too.

Ok.... now let's turn the entire analysis on it's head, just like a physicist might, by changing only one assumption. Let's assume the game is no longer being played in a normal ballpark on Earth and is now being played in a perfect vacuum instead (with the team in pressure suits, of course). What then?

The obvious answer is that the batter never perceives the ball coming his way before it passes him due to the incredible speed being too fast for his brain to process. So I suppose the next natural question is how far the pitcher and batter must be separated to give the batter a reasonable chance of hitting the ball.

The answer to that question: A LONG FREAKING WAY AWAY. A 90 mph fastball takes approximately half a second to reach home plate. Because the pitch is moving a 90% the speed of light, we must account for the 10% difference in speed between the ball and any light that would allow perception of the ball.

It's simple math, really. 0.5 seconds divided by 0.1 (or that 10 percent difference), yields a total flight time of 5 seconds for our major-leaguer in a vacuum to perceive the near-light-speed ball as though it were a 90 mph fastball. 5 seconds of flight time at 90 percent of 186,283 miles per second (approximate speed of light) is a total distance of... 838,273.5 miles.

That batter better have some AMAZING eyesight and reflexes, or some seriously advanced optics if he is to see an object of that size approaching from half a light-second (93,141.5 miles) away.

........ I am such a nerd.

Anything you can math, RagingTerror can math better.

Those were fantastic. XKCD impresses further.

LOL I liked the thing about speed of light baseball. I would pay more attention to professional baseball if there were more mushroom clouds involved. ;-)
