As we all know, in Einstein's theory of general relativity time and three-dimensional space are treated together as a single four-dimensional pseudo-Riemannian manifold called spacetime.

And under general relativity time and space are interchangeable, i.e. time can be exchanged for space and vice versa, e.g. by traveling at one mile per hour for one hour, you exchange an hour of your life for moving one mile in space.

But by twisting these principles beyond their breaking points -- we've got leather seats and a flux capacitor as options in the Volkswagen -- this evening I will travel 750 miles west and thereby travel back in time -- back to the age of the dial-up internet connection.

My voyage through time will last until January 4, 2005, so my postings until then may be sporadic at best.
