Julian Barbour, a modern-day "gentleman scientist" has a couple books devoted to time:
The End of Time (reimagining physics without time)
https://www.amazon.com/End-Time-Next-Revolution-Physics/dp/0195145925

The Janus Point: A New Theory of Time
https://www.amazon.com/Janus-Point-New-Theory-Time-ebook/dp/B083J14S57

My physics background is weak for understanding the finer points, but a lot of the material is accessible to people who enjoy questioning their basic assumptions. The idea of "nested nows" for example.

"Heat death in the form of thermal equilibrium is not the end state of the universe. Variety, expressed through shapes and ratios, can increase forever." #JulianBarbour #TheJanusPoint
