Multiple universes: The evidence is good

'What if you had an identical twin? What if you had 10 identical twins? A million twins? what if all of these "others" were more than just twins in the sibling sense? What if these others were literally "you," yet living independently in their own world or universe?

Astonishing as it may seem, this may actually be the case. There may be millions, billions, and in fact, an infinite number of "alternate" universes stacked like so much Tupperware within our own universe. In each of these other universes lives another you leading a full and very real life, just like your own life.'
