It does make sense about the second law of thermodynamics. When I look the universe with Copenhagen interpretation, the universe is probabistic and I get why we consider the quantum interactions are random. But we don’t know for sure that quantum mechanics is complete. Say if we could measure the position of an electron at a certain time, every theory and principle fails. So that makes the ‘true randomness’ a ‘not sure if it’s truly a randomness’ right? Yes, it’s kind of a near hypothetical case. I guess it would be a true feat of exploration at that time. Hope this timeline favors that.
