I'm not the one claiming that a bubble cannot form – it's modern, generally accepted physics that makes this claim.

There's no contradiction, Ariputra. The pressure inside the bubble is only slightly higher than atmospheric pressure, just enough to overcome the atmospheric pressure itself, the pressure of the liquid column, and the surface tension, plus a little extra so that the bubble can expand. That's all. (And if you still insist that the pressure inside the bubble is 10^8 Pascals, then take a pot of boiling water. Bubbles form at the bottom, the very same bubbles with the very same pressure. Let's say their total area, which they occupy at the bottom, is about one square decimeter. That is, the force acting on the bottom is 10^6 N, which is the same as placing 100 tons in the pot. Why doesn't the bottom of the pot fly out from such a force?). Any schoolchild knows this, and doctors certainly couldn't say that it's not explained. What modern physics hasn't really explained are some elements of macrophysics (although there are hypotheses, but not all of them can be experimentally verified at the moment, for example, wormholes), and the transition from quantum physics to macrophysics is not entirely clear in some areas.
