Supposedly, in a classic episode of Doctor Who, the Doctor calculated that there was a non-zero chance for all of the molecules in a rubber ball to align with all of the molecules in a wall in such a way as to allow the ball to pass through the wall. He then spent some time bouncing the ball off of said wall to test the theory. Perhaps something similar could be a backup plan for the guy in this comic.
IIRC, they were released from their imprisonment before the hypothesis could be fully tested. But I haven’t seen the episode in a very, very long time.
How is that possible? The ball is interacting with its own atoms via the electromagnetic field, right? Providing enough of a repellant force so it doesn't phase through itself. Why would the wall be any different?
I thought this kind of thing was quantum tunneling.
In a later scene, the companion would ask about the ball, and the Doctor would make an off-hand quip about it actually having passed through the wall, but they don’t believe it.
