Star Gates?

I know the movie Star Gate is just a movie and the series is just a tv series, but it makes you wonder if maybe there is a Star Gate.

I mean when you think about how big the universe really is, its theoritically possible that maybe an advance civilization could have make some sort of device that lets you travel through the universe much faster than using a space craft. We can't be the only ones in the universe, so perhaps maybe there is one?
