My teacher asked in classroom what would happen if there were no gravity. This question motivated me to think of some other "What if" kind of situations.
I thought about what would happen if there were no atmospheric pressure, since our bodies now tolerating a high pressure of 1 atm. My thinking is that in absence of atmospheric pressure everything will start expanding, even the human body.
I want opinions of genius minds and I shall be highly obliged to have your's.
