I If we wait infinitely long, will macroscopic objects undergo quantum tunneling?

[vanhees71]

Quantum tunneling of macroscopic objects is so improbable that FAPP I guess, we'll never observe it. Nowadays it's however possible to observe quantum behavior at pretty large, sometimes macroscopic objects, like entanglement between diamonds

Even in a universe with infinite time?

Even in a universe with infinite time?

Based on the current accepted cosmological model, chairs and walls will fluctuate into existence over vast amounts of times until eventually a chair tunnels through a wall.

Then the simulation will mercifully come to an end, and debts will be settled.

In some ways, that's not too bad. Still, if I were rich in the future, didn't get old, and we solved the entropy problem, wouldn't it be something to think about?

We now have three threads covering pretty much the same ground. This thread is closed, discussion can continue in https://www.physicsforums.com/threa...-theoretical-possibility-and-reality.1055408/
