>>7616208>Anyone with a fundamental understanding of science knows this shitMore like any idiot that read about the laws of thermodynamics applying only to closed systems and didn't read anything else.
The universe itself is is a closed system, subject to the laws of thermodynamics
>But muh heat exchange between parallel universesThen at the most extreme, the set of all universes is a closed system. Same thing.
Beyond that, entropy isn't something that exists only in closed systems. Entropy is an intrinsic property of a system that is as real as temperature, volume, heat, or any other quantity. Entropy is extremely rigorously defined from statistical principals. It's the one law of the universe that can't be broken in alternate universe simulations. You can simulate universes where the very formation of subatomic particles happened differently, and completely change all the fundamental principals of newtonian physics. Hell, you can simulate a universe of only photon like particles. They are all still bound by laws of entropy. Because entropy is based purely on statistics.
And closed systems? Read into any higher level mass/heat transfer, thermodynamics, physical chemistry or process design literature. Examining entropy in open, unsteady state systems is extremely common.
The notion that entropy somehow only exists in closed systems is completely false.
