Question	—	Would a very heterogeneous planet be spherical? I have a planet with homogeneous core and mantle, but a thick crust separated in two parts: the north half is composed of water and the south part is an alloy of heavy metals, making the north lighter than the south. What would be consequences on planet shape? The usual - not perfect - spherical for... (more)	—	about 9 years ago
Question	—	Would an AI try to create AIs to improve its life quality? Let's take a classic AI revolution scenario: An organic civilization seeking more comfort in their lives created robots with self-learning algorithms to make them more efficient. But while the AIs were becoming more and more intelligent, they started to want to live their "lives", wanted more than a... (more)	—	about 9 years ago
Question	—	Would there be evolution on a perfect world? Imagine a planet with the same climate all on the surface. There is only one living creature on this planet (let's say a plant to avoid food problem). It is perfectly adapted for the climate. And as there is no herbivorous animals, there is no reason to evolve for defense systems. In this case, wou... (more)	—	about 9 years ago
Question	—	How to prepare for a huge asteroid strike? The scenario is the following: a civilization with technology level similar to humanity's current, on a planet similar to Earth, shall be hit by a massive celestial body in approximately one year. The impact would be around three times more powerful than the one that caused the end of dinosaurs, but... (more)	—	over 9 years ago
Question	—	May an AI civilization grow peacfully with organic civilizations? Imagine a sci-fi world where many organic civilizations would have raised and have an empire between many planets and systems. Even if there is some political tensions, they all live in peace together. (A Mass Effect-like universe). Now, for some reason, imagine a race of machines, with a population...

Question	—	May a very short-lived species raise as a stable civilization? Consider a planet similar from Earth: very suitable for life, with vegetal and animal life forms thriving onside. I wonder if one of these life forms could raise as a civilization as humans did, if genetic evolution would have give to them at least the same intelligence, but a very short life expect...
