Mars-Mercury gravity X 2.5 = Earth-Venus-Saturn-Uranus-Neptune gravity
Earth gravity X 2.5 = Jupiter gravity
Someone?
in the event you interested in this I'll start a response. w/o double checking earth gravity is not the same on any other planet and properly stated you want to say earth = 1 and then the relationship to that one, if its twice 2, five times 5 or half .5.
gravity is not explainable as yet and theory is all over the place. most think that, mass, core construction, magnetic fields (N&S poles) are involved and is an internal action. my personal thought is, it also as to do with motion and atmospheric conditions. that is the all the above affect a condition created by a friction of atmosphere (and its contents- in our case
primarily nitrogen 77% and oxygen 21%), based on our mass and planet
materials. and is an external action of traveling around the sun, thru space around our Milky way and the galaxy movement, through space.
i justify my THOUGHT, to what could have been 60k years ago when the likely much thinner atmosphere (apx .7-8 of earth today) was changed almost over night to a very thick and much more carbon than today and gravity increased to say 1.2 or even 1.4 of todays. this was no doubt from
unusual volcanic eruptions and a very large meteor landing near what is the Gulf of Mexico, today. now is i am correct, and a 100 pound thing would weigh about 140 pounds, almost overnight and the T-Rex for instants would just lay flat till dead and the animal chain mostly down would be dramatically affected. Birds couldn't fly and so on...then as the atmosphere clears and over some time, the gravity is back to 1 and stabilized.
just a thought to encourage a question...
