A pretty quick read about a super-fast proton detected in 1991, with a nice set of comparisons to get the point across. Such as that the proton had enough energy:

to light a 40 watt light bulb for more than a second.

Yowza.

That said, included in the article is this:

[Star Trek's best ship would take] a little more than 21 years [to reach the center of the galaxy]. By contrast, an observer on board the Oh-My-God particle would arrive at the nucleus of the Milky Way, according to his clock, just about 3 seconds after leaving Starbase Terra. That's more than 9,700,000 times faster than the starship.

* bzzzz * wrong. It's only perceived as faster to the riders, the particle takes ~32,000 years (according to their numbers) to do the same trip, which isn't pointed out in that section. At which point our whole civilization is probably dead or passed you by long ago. And they've apparently forgotten about suspended animation.
