### A Tragic Wormhole Journey

What a tragedy. In this animation someone travels through a wormhole, from the University of Tübingen in southwest Germany to the French seacoast in Boulogne-sur-Mer.

Where is the tragedy you say? He is going to the beach!

Oh yes, the beach. That is the good part. The terrible part is that he spends very little time there, and then, RETURNS back to University, almost right away!

Beach? School? Beach? Work? Beach? Anywhere else? Beach? Hmmmmm.

This is a tough question, yes? NO !!! ALways choose the beach, over everything else!

Well perhaps he forgot his towel, and it will be a happy ending after all.. :-)

WORMHOLE MATHEMATICS - Quickie version

Theories of wormhole metrics describe the spacetime geometry of a wormhole and serve as theoretical models for time travel. An example of a (traversable) wormhole metric is the following:
$ds^2= - c^2 dt^2 + dl^2 + (k^2 + l^2)(d \theta^2 + \sin^2 \theta \, d\phi^2).$
One type of non-traversable wormhole metric is the Schwarzschild solution:
$ds^2= - c^2 \left(1 - \frac{2GM}{rc^2}\right)dt^2 + \frac{dr^2}{1 - \frac{2GM}{rc^2}} + r^2(d \theta^2 + \sin^2 \theta \, d\phi^2).$

 Beach = Good
 School/Work = Eh.           Not as good as Beach!

I'm not quite aware of how I should interpret these equations so as to understand why one can travel so quickly trough space-time with wormholes.

Dear Pr. Colyer, can you explain this to me?

Sure, however, unless you can find a bunch of exotic matter, create some negative energy, and figure out a way to channel infinite energy, you can relax and not worry about creating a wormhole anytime soon. :-)
