Kurthin

Kurthin is a fictional planet featured in the science fiction novel "The Gods Themselves" by Isaac Asimov. It is a world orbiting a star in a different galaxy than Earth's. The planet is home to the Twin, a sentient, three-bodied alien species that exists in a state of perpetual, synchronized duality. The inhabitants of Kurthin are described as highly intelligent and technologically advanced, having achieved a deep understanding of the fundamental forces of the universe. Their society is characterized by its communal nature and a lack of individualistic ambition, a stark contrast to human civilization.

The most significant aspect of Kurthin in the narrative is the development of a technology that allows for the direct transfer of energy between the Sun of Earth's galaxy and the star of their own. This process, while beneficial to the Kurthinians by providing them with a new and abundant energy source, has devastating consequences for the Sun, threatening to engulf Earth and its solar system. The discovery of this phenomenon and the subsequent interactions between humanity and the Kurthinians form the central conflict of the novel's second half. The unique biological and social structure of the Kurthinians is integral to understanding their motivations and their role in the cosmic drama.
