Every few years, there seems to be some brain theory that appears to have immense explanatory power to a lot of people and turns out to be largely off the mark, like "left brain/right brain", "mirror neurons", and now "dopamine reward". Will this ever stop? And what's next?

that time in relativity is basically space but with the opposite sign of metric tensor component. there is no change in that 4D, it is all static. how would you ever explain 'now' if that model is final truth?

Eternalist vs. momentary time does not yield different observables. On the classical theory level, it is merely a difference in notation. On the implementation level, it imposes very different demands, of course.

Trying to sketch in a single tweet: Time is rate of change on a flat regular topology as observed by an embedded computer (and thus relative to the rate of change of that observer). It emerges over the elementary state changes that give rise to the topological dynamics. Helpful?

mmhh... let me meditate on that one. What is the major difference in your opinion here to classical views of time?
