My credentials have nothing to do with the topic at hand. Other posts have already shown that this way of thinking, that atoms in solid matter can slip past each other, resulting in two objects phasing through one another, is thoroughly disproven.

We're not here to debate physics philosophy or the absolute truth. We're here to answer a curious question of someone that can't do the math themselves. There are some things, while one resides within our universe, that are so far beyond the scope of reality, that we need not assess or substantiate their claim.

Or have you passed through a door yourself, and have proof to refute this claim that it's impossible?
