About Time: The Physics of Time – with Carlo Rovelli

Time is seen as part of the fundamental grammar of the world. Yet there is little evidence proving it actually exists. This episode seeks to mop up some of the biggest misconceptions around time, and explores the theories that have shaped our scientific understanding of it.

Podcast guest Carlo Rovelli draws from his latest book, 'The Order of Time', to explain how people create a sense of flowing time in a world where it doesn’t physically exist – and offers a new model for thinking about time.

I read the Order of Time by Carlo Rovelli and it was brilliant; I think I had a brief moment where I understood it all, but it is already slipping away.

I too have read Order of Time and I am just starting to glimpse underneath the veil. Bells idea that reality is "none local" well of course, if there is no such thing as "instantaneous" . There can only be an instant - if there is time. If no time, then no such phenomenon as instant connection. But it is so hard to get your head round these ideas with our temporal brains. Our brains are state machines! For us the "present" is due to present_input and past_output. X_present = A.X_past_present + B.U_present .

First, with certainty, it is stated what time is definitely not, which of course requires one to fully understand what time is in the first place to be able to do so, and then it is said that time is not fully understood ????
