Stephen Hawking famously asked, “What is it that breathes fire into the equations and makes a universe for them to describe?” In the context of the MUH, there’s thus no fire-breathing required, since the point isn’t that a mathematical structure describes a universe, but that it is a universe. Moreover, there’s no making required either. You can’t make a mathematical structure—it simply exists. It doesn’t exist in space and time—space and time may exist in it.
