Jeffrey, either one define a universe constricted, that represent a 'fish bowl'. In such a universe a Lorentz contraction still will be observer dependent though, meaning that as we have a fish bowl to go out from I can make smaller fish bowls in it, 'systems' that I limit by some mean. In my 'system' I can define as many observers I like. Each observer having a different motion relative all other observers. I can also let each observer inside that 'system' represent a different mass. Each one of those observers inside my 'system' will measure a different time dilation, and defining a Lorentz contraction as a complementary description to a time dilation, depending on frame of reference you use for your observation, there also will be differently Lorentz contracted 'fishbowls', all locally defined.

Either that is a illusion, or it is true. If it is true then using a 'fish bowl' perspective becomes very tricky, as the system you defined is observer dependent, and also as there is no frame of reference more right than any other, including the one you used defining that 'system'. One also need to acknowledge that a Lorentz contraction makes no difference between a vacuum and 'mass', for example looking in the direction one travel at a relativistic speed.

It is observer dependent.
