From Eric Kvaalen, Les Essarts-le-Roi, France
The introduction to your interview with Laura Mersini-Houghton began by asking: “How did our universe begin?”
But, of course, her theory doesn’t tell us how it began(5 November, p 43). She says that “in the very first moment, before the universe emerged in space-time, you can think of the universe as a wave function in an abstract space of energies”. But how did that come into existence?
