I've often thought about many things at night when I can't sleep. There is one thing, though, that truly keeps me up thinking about it at night. If you believe in science, then you also believe in parallel dimensions and alternate realities (think Sliders tv series). The thought that keeps me up is, since I believe in alternate realities, if all our fiction is fantasy, then there must be a reality where our fantasy is real.

The reason I worry about this at night is because of one thing. If the said realities are real, then one of those advanced realities has a scientist or dictator working on some device to go to the other realities, and if they have made such a device, how long til everything we know as fantasy is burned asunder to reveal a new truth?

So... You think about bad science fiction when you can't sleep?

I think there are some false inferences going on here...

Even if there are "alternate realities", there is no science that I am aware of that would imply that there is a reality where our fantasy is real... Just because these alternate realities could be anything doesn't mean that there will be one for everything, even if there are infinitely many of them.
The so called many worlds interpretation of QM certainly does not claim that there is a reality where our fantasy is real. In fact, for many worlds, the assumption is basically that the laws of physics is the same for all those worlds. The only differences are the different outcomes from various quantum measurements.

What usually keeps me up at night is the noise that the people downstairs are making.

I apologize for all the assumptions. It is just I saw a discovery science special a few weeks ago and all the scientists agreed that, "We (the scientific community) would have to be fools to think we are alone in the universe. Likewise, we would be foolish to think our reality is the only one." The scientist who said this was the one in charge of NASAs warp speed testing (is that still going on though?). The special had the scientists in a room asking them questions where they all got to say their opinion, surprisingly everyone agreed with his quote.

Now that I stated my source as to why I made the above assumption about science, let me tell my logic for thinking the way I do. I was thinking that if these realities are infinite like scientist theorize, then that means that in one I'm a game programmer, in another I'm a serial killer, yet another I'm a bum, yet another I'm rich, I'm a president, etc. So it brings to reason that if the realities have alternate persons, then there are realities where are fiction is reality maybe not with the ficticious names we gave them though. For example there may very well be a reality where there is a Federation of Planets, Klingons, etc but there may not be a James T. Kirk, Picard, Riker, etc.

This is why I lose sleep once in a while, because if these realities do exist. Then what is to keep the advanced realities from figuring out how to reality jump? Granted this could be good or bad, depending of course.

Is there an Act of Dog?;D

I'll see your "many worlds interpretation",
and raise you "the hidden varible consideration".

The thoughts that keep me up at night are the ones that involve making cups of tea and smoking fags.

Does anyone really believe in parallel universes or do they just like the idea ?
I bet travel agents are keen on it, and unemployed journalists.

Today in Beta 10017, Sauron finally made peace with the west of middle earth in order to counteract the ongoing insurgency from Beta 10018 by the forces of Ganon.
Flights from Heathrow to the shire have all been cancelled.

Where's the evidence they exist ? I thought science was evidence based.

Mehehe, in North America that doesn't mean the same thing.

Finishing my current project tops the list, but rethinking the day's events (did I use the time allotted to its fullest potential, was I kind to others, etc.) and worrying about the war place highly.

Sometimes, I have nights where I wonder if things I've done years ago have been horrid mistakes and if I (and maybe the world) would have been better off if I'd have chosen a different path, and I end up not sleeping at all.

Bah, mistakes are underrated. How would you learn anything if you didn't make any mistakes?

Right now, what's keeping me up is the entire first season of Transformers: Beast Wars.

Everything contributes to the advancement of civilization. Some things directly improve civilization, and other things just teach us what not to do.

The nous, gumption or attitude is useless without that piece of paper, unless you think of something truly innovative.
