**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.

Future of Computation -- Fred Adams

Astrophysicist Fred Adams calculates the limits of computation, arguing we could run out of resources in just 32 years. And he discusses how alien civilizations could mine stars to create solar-system-sized "black cloud computers" detectable from Earth. From the 6th FQXi meeting in Tuscany.

What are the physical limits constraining the exponential growth of computation? And how might we overcome them?

In a talk that captures the spirit of the Foundational Questions Institute beautifully, astrophysicist Fred Adams began with a series of fairly grounded calculations looking at when we might run out of computational resources on the planet (spoiler alert: it’s a lot sooner than you might imagine) and ended with some fun speculation, by proposing that an advanced alien...
