The week's question
In December 2024, in the thread "Re: BRK: Why Not XOM?", BreckHutHigh asked the members: "What about the long road trips with kids?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

I may need some time to digest this. Very interesting.

phys.org - Thermodynamics expansion universe

The authors show, using the Grüneisen parameter, that continuous cooling of the universe is associated with a barocaloric effect that relates pressure and temperature and occurs owing to adiabatic expansion of the universe. On this basis, they propose that the Grüneisen parameter is time-dependent in the dark energy-dominated era (the current universe era).
