Take the tour ×  If I were on one side of the room and moved at
the speed of light to the other side of the room, to an observer
it would appear that I teleported. If time stops at that speed,
it would be instantaneous but we know that light is not
instantaneous (see light years). So I'm curious what the
difference between traveling at the speed of light and
teleportation is. I think teleportation has to do with
deconstructing objects and then reconstructing them which allows
them to travel through things etc., but is there any other
noticeable difference?  share|improve this question i don't
think teleportation is a well-defined scientific term. Wikipedia
states that is refers to "notions concerning the transfer of
matter from one point to another without traversing the physical
space between them".. in physical terms this would correspond to
disconnected worldlines. maybe more appropriate for scifi.SX. –
