I believe this sentence:"Today, it is thought that a universe, such as our own, is born into an energy state known as a "false vacuum," called 'false' because, unlike the 'true' vacuum in which our universe abides, it is

unstable." ..is icorrect?, it is stating a "Universe such as our own" eminates from a "FALSE-VACUUM" energy state, and then states that our Universe is abiding within a "TRUE-VACUUM" ?

Hi Richard,

I like the analogy of a loaf although I use the idea of a whole pie instead, but I would argue there is an obvious way of slicing the loaf or the pie. Since we invariably are slicing the whole of all universes in the multiverse, and inline with Tegmark's idea the universe is ultimately a mathematical system, I will call the whole zero, and think of it as the ground state. We can most obviously slice zero in half, thus dividing apart all positive numbers from all negative...
