A View From the Top
Thinking of causation as a "two-way street"—along which the passage of information can be inverted—could have implications for the origin of life.
Classic Article: Black Holes, Paradox Regained
In 2004, Stephen Hawking famously conceded that black holes do not devour all information when they swallow matter—seemingly resolving the "black hole information paradox" that had perplexed physicists for decades. But some argue that the paradox remains open, and we must abandon our simple picture of spacetime to unravel it.
Quantum Biology: Making Waves in the Natural World
Could quantum effects explain the mechanisms behind smell, photosynthesis and bird navigation?
The Accidental Universe
Have we been fooled into seeing one form of reality, with particular fundamental forces and laws, based on the peculiar way that we have chosen to measure time?
The Cosmic Hologram
Is our universe an illusion projected backward in time from the future?

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" ?
Which is it?..either way the initial inflation period, determines a...

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...
