Other leading physicists familiar with the research program have observed such a strong metaphysical predilection among their colleagues. As University of London theoretical physicist Bernard Carr has observed, “To the hard-line physicist, the multiverse may not be entirely respectable, but it is at least preferable to invoking a Creator. Indeed, anthropically inclined physicists like Susskind and Weinberg are attracted to the multiverse precisely because it seems to dispense with God as the explanation of cosmic design.”
