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.

Individual Stories
Towards a Quantum Internet
The Chinese quantum space satellite Micius has helped set an entanglement distance record and enabled the first demonstration of a quantum key distribution between a satellite and the ground. Team leader Jian Wei Pan describes how long it may take to establish a global quantum communications network, to Zeeya.

A Big Bang in a Little Room
Can we make a baby universe -- complete with stars, galaxies, planets and people -- in a particle accelerator? Cosmologist Eduardo Guendelman explains how it may be possible -- and how the theory could help the search for a model of quantum gravity. Recorded at the Physics Days Meeting at the Eastern Mediterranean University. Plus we discuss the new popular physics book on building a DIY comsos, by Zeeya Merali.
