Thanks for visiting and reading this imaginary thread. So, recently I tried to write a novel. It is an ongoing project, and very far from completition. I've read so many Sci-Fi stories before, and some do not follow general physics very well. I want to make a world that is believable, but also scientificly correct. It doesn't need to be so precise, but it has to differ a little bit. I wonder if this forum can help giving some enlightenment on the subject, despite it being Sci-Fi stuff. I may ask for some thought exercise, what would happen in a planet that has 0.92 less gravity than Earth or 9 m/s2? I've come up with some rough estimates, such as - Trees being slightly taller - People from Earth jump slightly higher - People from this planet suffer fatigue and knee injury on Earth So, if you have other ideas on what will happen to this planet and Earth people that move to it, let me know! I might ask for rough formula to your theories, for example h = 1/g on jump height. Please feel free to go crazy on this thread! I might need all details I can get. Thank you.
