You just said openly that Newton's Third Law doesn't make sense.

Basically, you're trying to tell me that negative pressure acting on an object in any plane doesn't cause a change in force direction of that object, correct?

So, if I were to assume you're correct, which, according to ALL the studying I've done on fluid dynamics, you're not, I'm getting the idea from you that airplanes just don't fly.

If negative pressure is exerted on any part of an object, the object will move in that direction. THAT is how lift works. Lowered pressure caused by acceleration of flow adhering to (but not solely becuase of) Bernoulli's principle. Once that has occurred, Newton 3 takes effect, in that all forces must equalize. If the pressure above the object is lower than the pressure below the object, the object will experience an increase in fluid buoyancy.

You can't argue with that.

The only way to counteract the force acting on the object is with an opposite equivalent force, i.e. the equivalent negative pressure on an exactly opposite point on the same shape, or two other exactly equivalent forces (plus the first one) acting on tangents which would cancel each other out, etc and so on.

The NET RESULT is zero lift in any direction, but the gross effect is still lift IN ALL DIRECTIONS due to pressure change IN ALL DIRECTIONS.

Imagine the object is hollow, with no entrance or exit to the interior space. There is dead air inside, at atmospheric pressure. That pressure causes the object to expand when the pressure outside the object is lowered, so the shape itself would expand at it's widest point, or the area on which the volume of gas inside could have the most effect on the surface of the object. Each segment of the object is, in essence, lifting away from the other segments. All segments working against each other in an equilibrium means that the net effect is zero.
