So this might be a too simplistic question on many accounts.
My pchem professor said to us that in QM, anything that can happen will. And it's a matter of probability, right? I guess I'm just curious what the scales are for something like, say, walking through a wall (the goto example for a lot of popular science books on QM)? Like, 1 in a billion or what?

The likelihood of that happening is so low that the universe is far too young for that to be an outcome.
At least, most likely. You never know, maybe something like that has happened.

probability and quantum possibilitiesIt should be noted that anything that can happen will happen with enough time. Even the probability above says that if the universe lasts long enough, a tunneling event of that magnitude should likely happen.

It may have been smaller, I can't remember now XD It was definitely e^10 to a really big power, but it may have been closer to 100 than one million. At that point though, what's the difference, really? It's not gonna happen, lol.
