Back in 2001, I changed fields completely… went from working for the housing and construction industries to working in science.

The toughest concept I learned – in addition to getting a crash course in just about every discipline out there (archaeology, astronomy, biology, chemistry, genomics, nanotechnology, proteomics, etc) – is that there are no absolutes.

Now, I thrive on absolutes, on guarantees, on infallibilities…. like knowing for certain that 100 cents makes one dollar or that 1+1=2 or that dogs bark and cats meow or that Friday is payday or that there are 24 hours to a day.

I get a little upset when ALIAS moves from Sunday to Wednesday nights, when my brother changes his email address and forgets to inform me, when the Euro starts to bitchslap the US dollar, when I finally understand that time is a constant (it does not pass – we pass through it).

Quantum Physics my friends – the multiple worlds theory. For a quick introduction, rent What the ^@!&@# do We Know?

So now, almost five years later, absolutes no longer exist in my world. And, I think my life is better for it, though it’s been a long process.

And it’s got me thinking…. IF this many-world view of reality is a possibility and IF some super-genius at MIT figures out how to travel between these universes and IF I could afford to travel in time (because we all know it’ll be ludicrously expensive when it’s first commercially available), then where would I want to go?
