In space you need some sort of power, but fuel runs out. gravity does not!, if you think like a submarines diving and submerging with air by making its tanks heavy or light. the idea I'm suggesting is making an outer surface that enlarges like a big balloon that would be attreacted by gravity. its well known large bodies in space atrrack, even bit ships in our ports attract each other.
to be clear I'm saying increase the surface area, the balloon would still have a vacume inside it, you could turn on gravitational pull by enlarging an object in space, the reduce it to carry on in the desired path
I'm not sure how big the balloon would need to be, but its my best idea so far on space propulsion.
you would have to fill the tanks with a material that is lighter then nothing (vacuum) so a strange material which has somehow a 'negative mass' so it floats in a gravity well ...
where are you locate? with a little luck already near on the westcoast
if you have some free time jump in your car or get a bus ticket and visit 2311 Los Robles Avenue /Pasadena wait for Sheldon Cooper from that well known reality show BBT to leave the apartment house and discuss that material research progress with him, he the one who might can help you progress the idea O0 ...but please don't tell him i gave you the address :-X

sorry I was not clear, you just increase the size of the ballon filled with vacume, not air tight, what I'm saying is increase its surface size.
PS: if you drop a feather and a rock in a vacume the fall at the same speed, so weight is not relavant possably.
the balloon hull always have a weight, isn't it ? and that pull the balloon filled with nothing down, regardless how big the balloon is
Try to get an appointment with Mr Cooper, he might take a few minutes to listen to you if he find the concept Fascinating!
Mike I loved all those episode of friends, thanks for the smile. I think I laughed in every show

in a vacume there is no weight . all things move at the same speed
Sheldon just thinks he is the most intelligent, steven H read this thread :)
Nevermind.
In space no one can hear you groan.

Nevermind.
This made me LOL more than anything else. If Trailrunner has to hold back... ;D
Gameleaper,
there is still MASS in space. Gravity needs MASS, not weight. Your space balloons won't have much mass. It won't matter how big you blow them up.

the planets and moons are different MASS but there all attracted by the gravity effect, we don't know really what attracts large objects together eg: ships in a harbour will move towards eachother but we don't know why. Maybe the balloon may need to be filled with gas and then compressed to reduce if MASS is important.

Ships alongside each other are pulled together because of the flow of water between the ships which causes a decrease in pressure.

the water would always all be the same pressure, the boats as they move are attracted by some unknown force, they don't drift random or away from other boats they drift towards each other, but I think they have to be big for it to happen

Man you really need to stop eating those mushrooms..... :idiot2:
There is no unknown force drawing ships together, and it isn't gravity either.
You really can't be this dim.... so are you just trolling us for shits and giggles?
