quantumstrides

if you separate one part of a quantum pair and keep it on earth and accelerate the other one to near c, will the one remaining on earth get smaller and more massive?

you cannot think of the universe and the ship as the same system without accelerating both uniformly and simoultaneously. there is no physical contraction to the universe, and no paradox.

i am curious as to what the result would be if you wrapped it in insulated wire and ran a current through it. kinda like an electromagnet... for instance, if i encase my ferrous fluid in a non conductive sphere, wrapped it in multi-(but symetrical) directional wiring, and run a current through it. i am trying to find out what kind of forces are produced, and if there are forces can they be manipulated to have a specific result. (edit for spelling and specifity)

I am an ameteur physicist (i actually have my degree in meteorology), and i have some questions about the EM properties of liquid metals or ferrous liquids when in spherical form. I understand if you are too busy or if i sound off, but if you do have the time to answer a few questions, it would be greatly appreciated. Thank you, Aaron Stewart
