Canceled movie in the 90s can't find any info on it!?

A movie was supposed to come out in the 90s about a woman sent on a course to the center of our galaxy around a black hole to return to earth in the future. I seen the commercial for it and the one part i remember from the commercial is the woman traveling warp speed like in the shuttle and the voice of some guy saying when you return everyone you know will be dead. Now apparently the movie was canceled by the government with no explanation why. What was that movie called and is there anyone who knows anything about it?
