Hello, I'm following an introductory course in modern physics.

So I understand there's a chance the particle appears on the right side of the barrier, and this has been experimentally verified.

Now I was wondering:

**can the particle also appear**

*in*the barrier?**If so**: is this directly measurable? If not, is this indirectly measurable? (for the latter, I'm thinking of the virtual bosons interacting for the fundamental forces: we can't directly measure them, but their effects are measurable)

**If not**: then what does it

*mean*that the probability function is non-zero in the barrier? Shouldn't the blue part be made zero then?

Thank you!
