If physics is computational, then what gets computed when? This is a surprisingly deep question. The seemingly even computation of the universe gives us a *clue*, not just to the nature of *time*…
[instrumental music] This somewhat simplified visualization of a pulsar and an astronomer's brain in the hypergraph holds that clue I was talking about.
The pulsar, the blue circle on the left, emits pulses of radiation, which make their way across the universe to a radio telescope and into the astronomer's brain, the purple circle on the right.
Applying rules to the nodes and edges of the hypergraph gives rise to all the activity in the universe, the rotation of the neutron star, the emission of the pulses from its magnetic poles, the propagation of those pulses through space, the detection of the pulses at the radio telescope, and the perception of the pulses by the astronomer.
