Re^2: Where should one report search.cpan.org breakage?

42 minutes and 12 seconds to be more exact. Here is the underlying math. One interesting feature is that any gravity train trip, from any two points, on any planet (of the same density as earth) will take the same time. One could speculate this is why Deep Thought came up with the answer 42 in the Hitch Hikers Guide to the Galaxy.

This does assume that the two points are the same distance from the centre. Which is rarely the case given that planets aren't quite spheres. In fact, if you were to dig a tunnel from London to Lagos and drop something into the hole at the London end, I don't think it would ever reach Lagos. Instead it would get most of the way there and then go back to London. IIRC this interesting little fact also assumes that the tunnel is straight - a tricky feat to pull off when most of the planet is hot and fluid.	[reply]

Ah, but you've completely neglected to address the economic complications of making such a tunnel! And they are peanuts compared to the political difficulties. The "frictionless" detail may also present a minor problem. But I think the perl 6 developers could certainly learn something from these considerations. - tye	[reply]
