Corrected entry: Rimmer is seen pressing a button before speaking into a microphone to send out a distress message. But Rimmer is supposed to be a hologram, an intangible being...and as such, can't touch things. HE is not capable of touching things until the Red Dwarf crew meet Legion in Series VI - then Legion upgrades Rimmer with a "Hard-Light" holographic drive, making him a solid being at last.
Corrected entry: Throughout this episode writing is backwards. Why, in a backwards universe, would writing be backwards? Surely it would be the correct way around, just that the people in this universe would read it backwards.
Timeslides - S3-E5
Corrected entry: When Lister changes the past so he does not get stuck on Red Dwarf, Rimmer is still there as a hologram, but he was only revived in order to keep Lister sane. If the history of Red Dwarf still remained the same (the radiation leak, Red Dwarf flying 3 million years into deep space etc.), despite Lister's absence, the captain would have surely been the only one revived as the most senior person on board. However, if for some reason, Rimmer WAS revived as a hologram, then he would have no memory of Lister as he would never have met him. Also, Kryten would still be aboard Nova 5, would never have discovered the developing fluid and would not have been able to show it to Lister anyway, so Lister could have never gone back to his 17 year old self to give him the tension sheet, therefore this whole episode is a paradox of itself and the Universe will now implode. Well, that's what you get for messing with causality.
Timeslides - S3-E5
Corrected entry: Want to know why Rimmer is alive at The End of 'Timeslides'? Here's a theory. Rimmer as a child sees himself from the future visit him to offer advice. He later works out that this was himself from the future. Later in the events of 'Stasis Leak', Rimmer is visited again by his future self. Because of his childhood experience, now Rimmer does not panic but takes his future self's advice and goes into Stasis, therefore surviving the radiation leak.
Correction: Sorry, but pet theories are not valid trivia.
Correction: However, it's possible for the radio to have holographic controls as well, perhaps reacting to the presence of a light bee, since in an emergency situation, a hologram may be the only one uninjured enough to send a distress signal.
