Okay so i have a friend in the US who has already seen a few episodes Of Red Dwarf, but is now working her way through them all from the start (or rather "The End" ). She just watched episode four last night with her nine year old son, who seemed to enjoy it, but he's a smart kid and has already has some questions as to the science behind certain aspects. I have my own throughts as to the answers, but i can't rightly remember if there were official explianations via the books or indeed later in the series, so any thoughts from you guys would be appreciated muchly. Whether official explanations or personal theories. So although i'm sure these questions have come up many times in the past, his initial question are as follows; Why does Rimmer need sleep if he's a hologram? And where does all the fresh food on the ship come from if they're 3 million years in space? The latter question came up when Lister gets milk for the cat. Seems a reasonable question to me. As i said i feel i can answer these questions, but want to make sure i'm not missing anything official and am also intersted as to any individual theories. There will likely be more questions added here in the near future too..
