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.

Thread 'Are Clone Ships a Better Alternative for Space Colonization?'

We've just had an interesting thread about generation ships, but I don't think that that is the most reasonable way to colonize another planet.

Thread 'Looking for story advice on ancient aquatic reptile breeding grounds'

I'm looking to pick the brains for a fantasy story of someone who knows a little about how ancient aquatic reptiles (~65Mya) might have migrated to breeding grounds in ancient Atlantic Ocean and its shores. The premise is that such creatures, last seen 65 million years ago, managed to survive through the ages on the shores of mid-Atlantic islands - now gone - and ended up in (relatively) modern times. The questions are mostly about how their migration patterns for breeding might have...

Thread 'AI Consciousness?'

I know this topic is extremely contraversial and debated, but I'm writing a book where an AI attempts to become as human as possible. Would it, eventually, especially in the far future, be possible for an AI to gain a conscious? To be clear, my definition of a consciousness being the ability to possess self-created morals, thoughts, and views, AKA a whole personality. And if this is possible (and let's just say it is for this question), about how long may it take for something to happen...
