APOD 2.4

The 11/14/2010 picture is an artist's representation of the concept of the multiverse. Obviously one cannot take a picture of an alternate universe, as with most astronomical phenomena, so the picture is really just a chance for the artist to doodle some circles and neat colors and call it a multiverse. Essentially, the multiverse is the collection of universes. Many scientists don't even agree that there are other universes, but they are hypothesized to explain where matter goes when it falls into a black hole, for example. It is very tantalizing to ponder what life is like for parallel analogues of myself in other universes. For instance, while I chose to eat a peanut-butter and jelly sandwich for lunch today, my parallel twin might have eaten a Caesar salad. Scientists are pondering other, less important issues pertaining to the multiverse, but there is virtually no way to empirically test them.
