This is an invited comment on both Gruber et al (2022) and Bunamano and
Rovelli (2022), which discuss the relation between physical time and human
time. I claim here, contrary to many views discussed there, that there is no
foundational conflict between the way physics views the passage of time and the
way the mind/brain perceives it. The problem rather resides in a number of
misconceptions leading to the representation of spacetime as a timeless Block
Universe. The physical expanding universe is in fact an Evolving Block Universe
with a time-dependent future boundary. This establishes a global direction of
time that determines local arrows of time. Furthermore time passes when quantum
wave function collapse takes place; during this process, information is lost.
The mind/brain acts as an imperfect clock, which coarse-grains the physical
passage of time along a world line to determine the experienced passage of
time, because neuronal processes take time to occur. This happens in a
contextual way, so experienced time is not linearly related to physical time in
general.
