I tried a search and was quite shocked that no one has posted anything on babylon 5. Now that is one seriously under rated sci fi. Lots of interesting physical concepts in it like centrifugal force on the earth ships to generate gravity because earth hasn't achieved artificial gravity yet. The growing of organisms for space flight etc. Personally I think if we don't become extinct and the innovation doesn't diminish we're pretty much on track to becoming a in-between of the Shadows and Vorlons I say this not due to technology but due to their philosophies which are extreme we don't lean on either end. But technology wise yea its on like donkey kong.
