Ok can someone explain to me how Humans manage to share the secret of hyerdrive with all the other races. Do they create thousands of hyper drive enabled probes and send them out across the galaxy. Clearly if they sent any sort of slower than light broadcast of the data it would take hundreds or thousands of years to reach the other civilizations by which point the humans will have probably already colonized most the galaxy using Hyper drive.
That part of the back story has never made sense how are humans able to disseminate knowledge of Hyperdrive technology without having met most races.
