There is 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, the surface tension, and a little more 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 ones, with the very same pressure. Let's say their total area, which they occupy at the bottom, is about one decimeter square. 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 this is not explained. What modern physics has not really explained are some elements of macrophysics (more precisely, there are hypotheses, but not all of them can be experimentally verified at the moment, for example, wormholes), and also the transition from quantum physics to macrophysics is not entirely clear in some places.

The forum's technical capabilities couldn't accommodate your thought.
