AI Thread Summary

The distance between the star systems Sirius and Alpha Centauri is approximately 9.5 light-years. From the perspective of Alpha Centauri, Sirius appears as a close double star with Betelgeuse, located less than a degree apart in the sky. This information supports the realism of interstellar travel in science fiction narratives, allowing for plausible changes in starship destinations.

Is it a bottleneck, how the possessed people will be able to receive...

Thread 'How would an Earth-like Planet fair with a Uranus like moon system?'

Earth has one large natural satellite in reality. This is only talking about the context of a habitable, planet that has the conditions as Earth, with similar axial tilt. It would have a moon system similar to that of Uranus. Let's say it has 6 moons, similar in size to Puck, Miranda, Ariel, Umbriel, Titania, and Oberon. These 6 moons would orbit in safe, stable orbits around the Earth-like planet. What would their apparent size, and realistic distance be from the Earth-like planet? What...
