The Stargate program is going good on Mars and the Moon-base. After they have made a few hundred space ships the size and similar shape as the Giza Pyramid but silvery white in color instead of gold like Gould used.
They had the coordinates of the Gould home world. The dropped a red Mercury atomic device into the sun of the home world. As they exited the solar system the Gould sun for their home world became a black hole and began sucking the solar system into it.
As they left there they had a few other stops in the IDA galaxy to turn the home world of the Ori into a black hole as well and the home worlds of the wraith and Asurans, mechanical creatures.
They then returned to their home system and lived happily ever after.
Yeah right sure they live happily ever after until it was time to pay income taxes.
