New Theories / Re: what causes gravity??
« on: 14/10/2015 13:36:53 »
I saw someone on here say WHY ask what causes Gravity, can't we just accept it is? Well It would certainly help a lot to find a way to create gravity on a long range spacecraft (simulating it using centrifugal force is not the same thing). OR to learn how to cancel it on earth to fly without aerodynamic forces or lighter then air craft. Most of the fuel to launch a space craft is used just to break it out of earths gravitational pull imagine if we could simply turn off the earths effect on the spacecraft at will? There are many reasons to ask What causes gravity. It seems to me most of what we know about gravity is the study of it's effects not it's cause. I am not a Expert in anyway but it does not take a expert to understand solving this question and then to make practical use from that would be a astronomically HUGE scientific breakthrough. Everything else is hypothesis until you can not only explain your hypothesis but actually prove it with practical application. I also know the way it is discussed in schools (Meaning K-12 education text books) gives the impression Newton Understood Gravity what he did was come up with mathematical formulas that explained the effects of gravity on mass and motion. (not to say that was not huge and quite brilliant especially when you consider how long ago he came up with those formulas and we still use them today) My fear it is highly likely that it is a force SO dependent on mass that to duplicate the gravity of earth in a space craft that works the same as gravity on earth would require a spacecraft that had the the same mass of the earth. In the end it may just be one of those laws of physics you just can not change even if we did fully understand it. But that does not mean we should not continue to try or ask why. Asking why is what science is all about. (To those more educated then I please be kind as I know I may be way off)
