How can merfolks stream video in a way much similar to our WiFi but underwater? Right now merfolks are totally envious of us watching a live stream video of cat(fight) via WiFi or satellite internet, ok ok I get it's not the speed but its latency... Urrrr. Nevermind that I sincerely hope that the merfolks can receive WiFi but obviously the signal doesn't penetrate far underwater... (more) |

How to explain one side of Super Earth is smoother than the other side? A spaceship flew across an unclassified region of the Milky Way galaxy and found a Super Earth in an unnamed system. The planet is almost twice as massive as Earth and is orbiting fairly far away from its parent star. Unfortunately, there is no liquid water and is deemed too cold for settlement. St... (more) |

Why bother programming facial expressions for artificial intelligence if humans are bad at recognising them? Set in the near future, robots and mankind coexist amicably due to the great technological advancement in robotics and artificial intelligence. They are everywhere and some took a human form. All of them are hardwired to obey the robot version of penal code which keeps updating. I kept wondering, sin... (more) |

Would it be more efficient to build fleets in orbit? My Dino theme park business didn't end well and I reluctantly fall into depression and decided to go into suspended animation to seek a cure. 200 years later, a lady claims she works with the military woke me up and wants to award a contract of constructing 1000 space ready battleships within 5 years...

Permanent flag for space pirates Space is filled with all kinds of things that are unkind to cloth, such as dust and radiation, and they are the reason why sticking a nylon national flag on the moon isn't permanent. In my world I would like my space pirates to compete for territories and even collaborate with corrupted government b... (more) |

Why would spaceships still have acrylic/glass windows when force fields are cheap and reliable? Force field technology has come a long way. The latest energy-efficient engines can guarantee stable energy output in any situation, making force fields extremely reliable and very cost effective compared to acrylic and glass. Power failure is a thing of the past. Force fields eliminate the need for ... (more) |

Can I program nanobots to behave like sperm and fool an egg? In short I'm looking at creating an artificial sperm smart enough to fertilize an egg and develop into an embryo, so that would mean the sperm must have some means of carrying information similar to DNA and interact with it. I think of it as a parasite scavenging for necessary material from the egg a... (more) |
