basically lots of gravity sufficiently far enough away.

Someone do the math here.

Take the size of our visible universe ... multiply it by lets say 20 ( arbitrarily )

Then use the gravity formula to calculate how much mass would be needed to have the mass at 20 VUs away provide say the gravity we feel from jupiter here.
