Description: SG10 are on a planet when one of the binary stars becomes a black hole. They try to escape by dialing Earth, but fail to get back. The SGC sends a probe and sees the black hole, but then they find they cannot disengage the wormhole and the gravitational effects are starting to effect Earth. SG-10 is trapped on a planet where a star has imploded creating a black hole. The time warp created by the astronomical event causes time on the planet to move very slowly in comparison with those away from black hole, though for the SG-10 team time would seem to be going forward normally. With the Stargate at the command center open, there is some slim hope that the men could escape but when it seems hopeless, their attempt to close the portal is unsuccessful. As as result, the gravitational effect of the wormhole begins to affect time and space on Earth, now restricted to the command center but spreading and over time, it will affect all of the Earth.
