Or straight up CGI with the guitar floating down the corridor...lol Seriously, with all those sensitive electronics way up there in outer space, wouldn't want a floating guitar on the loose to possibly damage that laptop. Do you ever look at the wiring in there? What kind of electrician would have a mess like that going on? Am thinking its just for show. props on the set. Same with all those cameras with big lenses......where are all the photos from those cameras? How come diligent recordings of the constellations have not been kept with daily photos to record them from their position? What science is going on up there? Looks more like theater to me.

Theater strune with continuity errors at that....like how come in one episode of men in space, a news person is talking live with an astronaut dry brushing his teeth, who explains how dangerous even one loose drop of water would be aboard their space craft up there in outer space.....and in another, we see a woman with her hair ridiculously permed, probably a couple of cans of aquanet to hold it up like its floating....and she laughing, doing back flips and spilling water everywhere trying to catch it in her mouth?? How does that work? Script continuity error.
