The document discusses four levels of possible parallel universes. Level I proposes that other universes may exist beyond the observable bounds of our own, as space is believed to be infinite. Level II suggests that other universes could have formed from bubbles in the early inflation of the universe. Level III describes the multiverse theory arising from the quantum mechanical many worlds interpretation. Level IV encompasses other mathematical structures that may constitute universes under different physical laws.

Powerpoint Templates Page 3 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.

- 6. Powerpoint Templates Page 6 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

- 8. Powerpoint Templates Page 8 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.
