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.

I agree that the nature will take always the road if we cannot solve or if we disappear, but we have the possibility to solve.

Hawking genious is solving problems about black holes that do not exist.

What a great thread! I'm just looking at it and am glad to see so many friends (in spite of differing views) from previous contests. In particular Christian Corda congratulations and a big hurrah! And Lorraine Ford I like your physics and political courage in support of senseable science (IMHO). And Akinbo thanks for your previous support and level headedness. And hello to everyone else.

And Pentcho if I were coach of a football team I would want you on my line, I have not seen anyone...
