Multiverse

The multiverse is a vast collection of parallel Universes. Many leading cosmologists believe that parallel universes are likely. In some universes the physical constants may be the same as in ours. In others the physical constants may be different and beyond our understanding. Laws of science that we know simply may not apply there. We cannot imagine what laws of science may or may not apply there. We cannot imagine what types of life may or may not be possible there. Scientists and science fiction writers try to imagine it.
