My observation was from the view point of physics and not of engineering.
If I take a balloon that has a little bit of air inside and place it into a bell jar, then evacuate the bell jar, the balloon will expand and the density of the air inside the balloon will decrease. Right?
If the laws of physics work on the small scale of the bell jar demonstration, then why could it not work on the larger scale of the planet.
I am not arguing against the continental drift phenomenon. I am simply saying that perhaps the planet Earth could become larger if the atmospheric pressure is reduced. The mass of the Earth would remain the same, or it may get more massive due to the dust and meteorites that rain down every day, but essentially it would maintain the original mass and gravitational field, only the size would change. Same as the change in the size of the balloon in the bell jar.
Keep smiling
