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,
