First Things First: The Physics of Causality
Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
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.

Gravity's Residue
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.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Spacetime Squids
Quantum physicist Sorin Paraoanu talks about building an artificial spacetime in the lab from SQUIDs--to test inflation and quantum gravity. In this extended interview he also talks testing the Landau-Zener formula beyond its limits and amplifying the vacuum. Recorded at the quantum foundations meeting in Erice, Italy, sponsored by COST.

Fantastic picture!

Mr Tegmark can make the multispheres if he wants :) but please play in a pure universality and not with bad tools !

a bridge in geometrical algebras ???? :)

all my net is checked even here ....for the prize in algebras ??? It is not cool in fact , I have seen the nobel prize in maths .what is this story ??? Perhaps Mr Tyson and Tegmark can explain me ??? I am not parano I know just the human nature but I am christian also, so I can pardon .... respect me and I will respect you .
