Parallel Universes
• The simplest and most popular cosmological model today
predicts that you have a twin in a galaxy about 10 to the 10^28
meters from here.
• Space is infinite in size and almost uniformally filled with
matter, as observation indicate.
• Each universe is merely a small part of a larger “multiverse.”
• This idea of Parallel Universes is grounded in well-tested
theories such as relativity and quantum mechanics, and it
fulfills both of the basic criteria of an empirical science: it
makes predictions, and it can be falsified.

COSMOLOGICAL DATA support the idea that
space continues beyond the
confines of our observable universe. The
WMAP satellite recently
measured the fluctuations in the microwave
background (left). The
strongest fluctuations are just over half a
degree across, which
indicates—after applying the rules of
geometry—that space is very large or infinite
(center). (One caveat: some cosmologists
speculate that the
discrepant point on the left of the graph is
evidence for a finite volume.) In
addition, WMAP and the 2dF Galaxy Redshift
Survey have found that space
on large scales is filled with matter uniformly
(right), meaning that other universes should
look basically like ours

Bubble Nucleation
A QUANTUM FIELD known as the inflation
causes space to expand rapidly. In the bulk of
space, random fluctuations prevent the field
from decaying away. But in certain regions,
the field loses its strength and the expansion
slows down. Those regions become bubbles.
