In an effort to locate a planet that is capable of supporting life, a party of explorers venture through a wormhole in the universe. They undergo time dilation as they travel through the wormhole, which causes time to move more slowly for them than it does for those on Earth.
Once the explorers locate a habitable planet, they decide to live there. Once more, they are subject to the time dilation effect as time moves more slowly for them than it does for those on Earth. The explorers eventually become immortal as they start to age more slowly than individuals on Earth throughout time.
