Yeah, think I get it now, any man made construct is still part of the universe despite its location and/or acceleration. I guess you can tell I'm not formally educated in physics, but I do have an interest in it, sorry if my question was unclear.
I see, but then is there a point at which gravity is taken out of the equation and self propulsion over takes the initial force, could a object between the galaxies brake free of the expanding universe?
If the universe as a whole is moving at great speeds and spaces is a mostly vacant vacuum why aren't space shuttles lost when they brake free of gravity?
