I enjoyed both SciFi series & accept that the both stories require such mechanisms to avoid some problems related to traveling between solar systems and interacting with cultures in other solar systems. Star Gate is SciFi: There is equipment at the destination. Star Trek is fantasy due to lack of receiving equipment. I do not expect either technology to be a future development. The Star Gate seems vaguely possible, although I wonder about the time required. My wonder concerns the implications of instantaneous communication of information, especially over large distances. There is an implied (or perhaps explicit) use of worm holes in the Star Gate technology. It boggles my mind to think about the topology/geometry of the universe if worm holes are essential to the transport.
