In the fundamental physics of the world, there is neither space nor time
I&#x27;m not sure about entropy arguments for explaining the direction of time. On Earth, the entropy doesn&#x27;t change much over time, thanks to a constant stream of low-entropy in the form of radiation from the Sun. Overall, the system is increasing in entropy. But why do we, on Earth, need to care what happens in the Sun? We could just as well go backwards in time as forwards, but influencing the past seems to be extremely difficult (just try kicking a football backwards in time).
