The Existence of A Parallel World

[Laurell]

In REBORN!, isn't this the one called Phalaenopsis Paradox? The concept is named after a group of orchids (class Phalaenopsis) which create new branches when you divide original branches.

What if you found a portal to a parallel universe? What if you could Slide into a thousand different worlds? Where it's the same year, and you're the same person, but everything else is different. And what if you can't find your way home?

DAMN! That's what I'm talking about! The eeriness that the idea gives you...

And another question:
WHAT IF SOMEDAY, SOMEHOW, YOU FOUND YOURSELF FACE TO FACE WITH A PARALLEL VERSION OF YOURSELF?

I'm under the impression that you've never heard of the series called Sliders, in which case (if you like the concept so much), you should go check it out if you want.
