Are irreversible processes absolutely irreversible, even given infinite time?

[Kinker]

Entropy reduction or quantum phenomena can occur microscopically, but entropy reduction is absolutely impossible by chance, and if a macroscopic object's wave function collapses due to measurement, does that mean that the macroscopic object will never be able to cause quantum phenomena? Even in a universe with infinite time?

You have already asked basically the same question twice in previous threads:

https://www.physicsforums.com/threa...ic-objects-undergo-quantum-tunneling.1055304/

https://www.physicsforums.com/threa...-theoretical-possibility-and-reality.1055408/

Both threads were closed because you kept belaboring the point even after your question was answered. Enough is enough. Do not post on this topic again; it's already been addressed as much as it can be.

Thread closed.
