Disk size and speed.... (Score 1)

I think the disk size and speed play the part in how much it will change the affect of gravity of something. Since Gravity is according to mass then even if we obtain 100% of earth then another larger plaent would be less than 100% but a 50% reduction her on earth would be greater in or on somewhere like the moon. I have though if you spong a hollow disk at hight speeds and then after obtaining that speed if you sping it around you it will force you as the center of gravity and you would hover. Well guess we will have to see on that one if we ever live to see that day comeing. Hey who knows it might be sooner than anyone thinks if they prove this.
