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.

Dissolving Quantum Paradoxes
The impossibility of building a perfect clock could help explain away microscale weirdness.

The Cosmic Clock Ambiguity
The way we choose to mark time in the early universe could profoundly change the fundamental laws of physics we measure. Physicist Andreas Albrecht discusses his research and whether it means we'll never find a unique theory of everything.

I too thoroughly enjoyed this short talk. Like Andreas Albrecht I have long been satisfied with Hugh Everett's many worlds hypothesis -- not at all a fantastic or preposterous notion -- and requiring fewer ad hoc assumptions than conventional interpretations of quantum theory.

Albrecht finds that clock ambiguity "deeply undermines" the "concreteness of physical laws." Perhaps -- however, when one discards a probabilistic wave function for continuous measurement functions, concreteness...


Hi Paul,

Thank you for your kind words! We hope you enjoy future editions too.

I think Andreas Albrecht would admit that even he didn't fully grok the implications of his work immediately! You can read more about it in this article by Bob Swarup: "The Accidental Universe." There you'll also find a discussion thread about his theory. Occasionally, our physicists dip into those threads and answer questioned posed to them there.


Really enjoyed this podcast. This was the first I have listened to of this series, and I plan to subscribe. I have to confess I didn't fully grok Anders Albrecht's idea about the choice of time in the early universe and the physical laws, but it is a fascinating idea. I think,
