Star Trek - First Frontier

the long version

An experimental shield system thats tied to the warp engines is tested near the largest star in the galaxy, but as they test their new shields near the star a gravitational like black hole is created and there only escape from the crushing gravitational forces is to enter with due haste to save the ship. Soon the learn that they are in a parallel universe where everything seems the same, but it is not only different but a hostile universe. To correct this anomaly kirk spock mccoy and a well rounded science team must travel 64 million years in earth's past to correct what went wrong. It is the jurassic period with many dangers, but soon they discover a species that is much too intelligent to be a coincidence.
