They at least brought up the falling through the floor bit on the SG:1 spoof, Wormhole Extreme. I think the director told them not to worry about it.
Well (non-floating) ghosts can walk through walls in horror movies, yet don't fall through the floor. If someone is out of 'phase' with this reality, why would there even be an Enterprise there? Or, how could they hear and see other people, yet the reverse isn't true? I could see everything gradually re-emerging when they were slowly brought back into 'phase'. But wouldn't you figure how Ro and Geordi showed back up to other people when Data found the technobabble explanation and brought them back into phase, is how other people would show back up to them? Suspending disbelief is the only option!!!
That's right...EM was the one where they were in Sloan's mind Those two really did tend to go where no one has gone before
Whenever they went to the holosuite to play their Alamo program, it was really a gay bathhouse. That's why no one else was allowed to join them.
