Probability of hand through a wall vs an electron

Click For Summary
SUMMARY

The discussion centers on the probability of a human hand passing through a solid wall compared to an electron being 1 meter away from its nucleus. It concludes that the likelihood of a hand penetrating a wall is significantly lower than that of an electron tunneling, given the vast number of particles in a hand (~10^23). The probability of even a single particle tunneling through a wall is minuscule, emphasizing the improbability of macroscopic objects like hands achieving such a feat.

a friend and I were trying to see if it would be more probable to put your hand through a solid wall, or for an electron to be 1m away from the nucleus (consider the electron is the only particle around).

would this even be possible to calculate?
what would we do?

thanks!

I think the chances that your hand will pass through a wall will be smaller. For even 1 particle to tunnel through a wall, the probability is miniscule, and you have to do that for all ~10^23 particles in your hands.

But of course the answer depends on the specifics.
 
Well, the "wall" could be 1 atom thick...maybe...in which case they may be comparable...XD
