Movie review

I watched the new Star Trek (came out in 2009) movie yesterday and realized that the one part was wrong. There was a star that was dying and it went supernova. Spock was in charge of saving the nearby planet but was too late and the supernova destroyed the planet. Spock still had to contain the supernova though so he injected "red matter" into it and created a black hole inside the supernova and swallowing up the explosion. Then he and another ship got caught and traveled through a black hole and came out back in time. This can't actually happen because you wouldn't survive going into a black hole and it definitively wouldn't be a time portal.
