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.

today in physics there are two fundamental approaches to time. The first and most common approach says we use clocks to measure the time component of space-time, space and time being confounded as the basis of physical reality. However this approach has no experimental support. There is no evidence whatsoever that clocks measure one aspect of space-time, and in truth we cannot observe space-time at all. The second approach here presented says time is merely run of clocks in...

Amrit and anyone else who thinks that time has no "arrow",

According to the Prime quaternion model subjective time most definitely has direction. All macroscopic objects are in continuous motion along the 4th dimension of the quaternion spatio-energetic continuum. This motion gives rise to subjective time, gravity and creation of matter at all scales. There is no stopping or going in reverse because this motion also holds all matter together. This motion can also be considered as decrease...

An arrow is a lethal quantum of action. It is a distant action but not a spooky one. Let's consider two two simultaneously shot bullets, one with positive "spin" the other one with negative. They have a good chance to coexist for some coherence length. However, I doubt that they might be suited to build a computer with the promised extraordinary performance. At least, I have no idea how to individually steer bullets in flight, while I recall claims that quantum computer are available. If I...
