Looking back on my life, there are a number of really stupid things that I almost did. Now I find out that somewhere out there, I actually did do them. How embarrassing is that?

[Sir Gawain]

This is old news. I read about this stuff back in the 80s.

Is there a copy of you reading this article? A person who is not you but who lives on a planet called Earth, with misty mountains, fertile fields and sprawling cities, in a solar system with eight other planets?

Of course not, that would be silly. But let me get the opinion of my friend Larry, who lives in my eyebrow. Larry?

Does anyone know of a way that I can get into one of those parallel universes?? I'm not all that happy being in this one.

[CJ Wolf]

that must mean that there are two hillaries too! AAAAAGGGGGGGGGGHHH! the horror!

[Just another Joe]

So I actually AM the Beloved Emperor of the Universe somewhere?

Hey, buddy, beam me over! I'll be your body double.

[Servant of the Nine]

The universes are only parallel to a Democrats standard of factuality.
They actually are just more or less, kinda, maybe, in the same general direction.

Tales From A Parallel Universe?

When do we leave!?

If there is, why is HE the one that sold all of his Internet stocks and used the proceeds to buy out-of-the-money QQQ puts in late March of 2000? Huh, why? And can he loan me some money?

[Paradox]

Somewhere out there, Monica didn't dribble, and President Gore is still wondering what to do about all the AlQaida attacks on US soil..

I am not really an expert on Cosmology, but I suspect that the author of this article isn't one either. Let me state a why I think this is bogus (and why Scientific American should know better):

Most mainstream Physicists believe in the Big Bang. The Big Bang theory stipulates that at the beginning the volume of the universe was zero. After that, it expanded (extremely rapidly) and continues to do so, such that the total volume of the universe grew and continues to grow at a high but finite rate. If you start with something finite (zero) and over a finite period of time add finite quantities to it, you end up with something finite. My Point? The universe is just big, not infinite. Something around 5*10^9 to 20*10^9 light years across. Big yes, but 10^10^28 light years? Give me a break!

I suppose poeple do enjoy reading an article like this, but I thought Scientific American tries to be scientific.

[The Duke]

Maybe in the other universe I took the BLUE PILL!?!?

The idea of such an alter ego seems strange and implausible, but it looks as if we will just have to live with it, because it is supported by astronomical observations. The simplest and most popular cosmological model today predicts that you have a twin in a galaxy about 10 to the 1028 meters from here. This distance is so large that it is beyond astronomical, but that does not make your doppelgänger any less real

Can I claim him as a dependent on my taxes? Because if I didn't exist, he wouldn't either. That should be worth something, especially in an age when you can get a tax credit when you didn' pay taxes...

Parallel universe bump.

I knew it! This am Bizarro World!

Is Jherek Carnelian lurking?

[MEGoody]

The idea of parallel universes has been floating around for a long time. Sort of like the food irracacycle on the Jetsons or the little green men from Mars.
