Time and space travel

Hello,

I know I already covered this but I was J-walking across Richmond Avenue today near Augusta and it occurred to me that time travel is not as simple as it may sound. I have no idea why that when I am crossing a street and hurrying to not get run over that I would think about such a thing but it is a fact.

In the movies, whenever there is a time machine, the "travelers" always end up at random places at random times since the "kinks" have not all been worked out. But since the Universe is everexpanding and Planet Earth is constantly moving, it is impossible that time travel would work without some fairly lengthy calculations.

As far as time travel goes a trip down "memory lane" is about as real as it is going to get. At least considering the parameters of the physical universe as we know it.

Like I said, I know I have covered this but I still am puzzled why I would be thinking about this while quick-stepping across the road to avoid traffic. This may seem like a trivial concern but so what?

Some people think the world is going to end in 2012.

As far as I am concerned, if there is an asteroid headed towards earth, I don't want to know about it in advance.

For all practical purposes, the world ended for Nostrodomus and the Mayans a long time ago.

The other day I was watching a show about a scientist who found blood vessels in dinasaur bones. They seem pretty certain that they are going to be able to get some dinasaur DNA and put it in chicken embryos and make dinasaurs again. The scientists have come to believe that birds are all decendents of dinasaurs and share the same dna so if they can just make it turn on and off the right way and wha-la.
