@#8049 Yep, it's just bad translation to English. The little chemistry I studied, I studied in my native language :) I'll edit. (more) |

A: Was the total amount of water on earth ever significantly different? Kind of depends on whether you mean water as in H2O molecules or water as in state of matter = liquid. The amount of liquid water will naturally vary a lot depending on seasons and warmth. We know that the temperature on earth has varied a lot in different time periods. In warmer periods, more water ... (more) |

How exactly can you reverse it? The sea water will freeze there naturally if the climate is cool enough all year around. Seems to me the only way to reverse it is to drop global temperature back to normal levels. What's "climate engineering", sounds like something from sci/fi. (more) |

A: The more horizontal a building (on planet earth) is, the more years it can survive a collapse? This is general mechanics: all objects have a center of gravity. On a square-shaped house, this center is right in the middle, at coordinates (width/2, height/2). The wider the building is in relation to the height, the closer to the ground the center of gravity gets. A building might collapse whe... (more) |

Homo sapiens fit the bill very well, save for the "no tool" requirement. A group of early evolution humans could kill a mammoth using nothing but spears and hunting tactics. It's quite feasible that humans would also be able to kill such animals even without tools, by stressing them up and eventually... (more) |

@Pastychomper†Yeah so some other means of credentials must be used in parallel, there are many problems with this technique. But lets face it, what we consider secure every day is not. We still rely on things like photos and signatures to this date, which are very easy to forge. It's just _the illus... (more) |

A: How do you establish identity when people can change their appearance at will? One obvious answer is RFID tag microchip implants, for example attached to the ear at birth, at the same time as someone is given their personal credentials. The body can change but the chip will remain the same. This technology is already available today, used on pets and livestock etc. There are... (more) |

I don't think it is clear from your post if the creature can fly or not. I'm assuming it can't? (more) |

A: How do I realistically keep my large mammalian predator hidden from other pack hunters. I don't think it is feasible for an elephant-sized hyena to hide on the actual hunting grounds, least of all from predators that have similar excellent senses. What it should do is to lay low some distance away from good hunting grounds, then watch the sky for carrion birds. If a predator has suc... (more) |
