Contemporary physics seem to indicate that there are good reasons, theoretically and physically, for an idea that there is a plurality of worlds. This concept has come to be understood as the multiverse. The multiverse is not monolithic but it is modeled after the contemporary understanding of an inflationary model of the beginning of this universe. Max Tegmark has championed the most prominent versions of the multiverse. Tegmark has made a four-way distinction.
I have gathered together all my posts relevant to the multiverse. Since this is one of the biggest topics on the blog, I thought having all the posts gathered into one place would make finding the content much easier.

The Drake equation is advocated by SETI (Search for Extra Terrestrial Intelligence) to show that the probability for ETI has a high probability (N).
- N* Number of stars in the Milky Way
- fp Number of habitable planets in each system
- ne number of planets that are Earth like
- fl number of planets that emerge from inorganic matter or organic precursors
- fi fraction of those planets on which intelligent beings also evolve
- fc fraction of those planets on which sufficient communications technology arises
- fL fraction of average planet lifetime
The problem with the equation is that each f is a number between 0 and 1, the product of the equation will be vastly lower than the total number of suitable stars in the galaxy N*. Many variables are unknown. So, the numbers that are brought in depend profoundly on the assumptions we bring into the problem.
