Thread: Propultion

I thought of something:
What if you could make a gravity inverter magnifier. You could focus on a planet or star and intencify the gravity from just that point. You could travle the entire universse like spiderman. Pulling yourself toward a point and then getting a new point.
I saw a experiment on this on tv. Where they statically charged a ballon and then mooved water with it. If you can do that why doesnt someone invest 50billion into this. It would be a greater invention than the computer.
