The agglomeration of said mass will increase the gravitational pull said mass can exercise on other masses. This sphere has an amount of mass in the 10 to the 24th power kilograms. Let us simplify the earth to the shape of a sphere to simplify it. Ok let us use the application of Newton’s Universal LAW of gravitation and Kepler’s Laws which is the gravitational field. The idea that straw-based drinking has anything overcoming gravity is the opposite of what I believe. The muscles of your mouth and lungs created a partial vacuum inside you, and the room's air then pushed the fluid into that partial vacuum. The fluid rising up a straw is caused by gravity pulling the atmosphere down creating its ~1bar of pressure. That simple vacuum can easily overcome “gravity” which is the opposite of what glerfers believe.ĭo you really think you've created a perfect vacuum inside your mouth each time you've had a milkshake? We can prove this easily by creating a vacuum using a straw and such up liquids due to the pressure differential between the vacuum in your straw and the liquid which is under atmospheric pressure. What the atmosphere does close to a planet is not one of those contexts. Most of it is so close to being a true vacuum that it's normally a silly waste of time to mention the difference. It's unfortunate that so many people think it is. There can be no pressure (water or air) at any distance from earth unless there is a barrier, or so-called “space” is not a vacuum. If it wasn't: why aren't we all dead from suffocating in argon and carbon dioxide? They're both denser than oxygen. Water vapour aside, it's pretty mixed up homogenously all the way up to. Different gases exist at each layer of the atmosphere - do you not agree?
