Discover Magazine quotes UB physics professor Will Kinney on renowned scientist Stephen Hawking’s last paper. According to Discover, Hawking and co-author Thomas Hertog submitted a paper to an as yet unknown journal dealing with the “multiverse,” a motley collection of universes that exist simultaneously. Kinney explains a multiverse theory called “eternal inflation” to Discover, telling the magazine, “Eternal inflation creates an infinite number of patch universes, little bubble universes, all over the place with this inflating space between them.” As Kinney points out, however, Hawking and Hertog don’t suggest ways that we might be able to see evidence of the multiverse, meaning that their theory remains, for the moment, untestable.
