In Star Trek, people eat food on the holodeck. Does the food disappear when they close their mouth? Why do they say it tastes good? Are they just roleplaying? Or does the holodeck special replicate the food like the replicators? If so, then why don't the crew of Voyager just eat on the holodeck, avoiding the need for replicator rations? In the first episode of Voyager, they mention the replicators and the holodeck run off different energy signatures, this why there aren't holodeck rations.
P.S. These are the kind of things I think about when procrastinating.
