Investigating how the quantum measurement process might be related to the emergence of intelligence, agency and free will.

Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

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...
