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.

Thermo-Demonics
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.

These astute Australian astronomers claim to know that although the stars we see with our naked eyes emit light and radio waves, their radio telescope has detected a different kind of radio wave emanating from some sort of very cold gas which existed before it started forming into the first finite stars. But if the extremely cold gas formed the finite first stars, how on earth is it still emitting the special radio wave solely to the Australian radio telescope? Why could not the ultra freezing...

I am ever so glad that the alert astronomers have actually detected (finite) signs of light from the first stars in the universe. Of course, it would have been better had they spotted actual light from the first stars, but the fact that they were able to isolate the first (finite) stars (without confusing them with the second set of (finite) stars) is yet another sparkling example of scientific capability at its most profound.
