Planet Blob - variable gravity On the planet Blob there is an unusual phenomenon. It is known to emanate from the planet's core but 2018-level scientists have no understanding of it. The phenomenon Gravity isn't constant. It varies between 1g (Earth units) and 0.5g. The variation is sinusoidal at a frequency of 1hz. The inhabit... (more) |

Aquatic aliens and the effects of acceleration in space-flight A sentient species of water-dwelling aliens achieve space-flight. Their living quarters contain water [no free gases]. They have evolved over millions of years to regulate their buoyancy at will. Question Will they be able to withstand much higher acceleration than an air-dweller. Reason for qu... (more) |

Is it possible to survive just by absorbing food and water through your skin? Part 1 The outer layer of skin of a human is called the epidermis. It is supposed to be waterproof, however: Using any current science and substances, would it be possible for humans to survive for two months purely by absorbing substances through the epidermis? The skin must not be pierced or otherwise ph... (more) |

Moon take off without rockets Take-off in a craft with rockets allows a gentle acceleration that doesn't kill the occupants. Given that the Moon has no atmosphere: Is there any current technology that would allow safe takeoff without using rocket propulsion? A giant spring for example? You can assume that technology is today's... (more) |

Swimming in space. What is the mechanism? A large (compared to Earth life) species of creatures live in space. They gain energy from interstellar dust and starlight. How they do this is a separate question so not relevant here. However they can adjust their metabolism to eat enormous amounts quickly when food is available or hibernate for th... (more) |

Post-Apocalyptic Earth. Escape from Warehouse Moon In its heyday Earth was a great interplanetary trading post on account of its low gravity moon which was used as a warehouse for all kinds of goods. The Moon was covered almost entirely in large warehouses and each had a staff of thousands. These people were manual workers, management and administra... (more) |

Shrinking people and objects - what physics could accomplish this? Popular science fiction is full of examples of people and objects being shrunk down to the size of insects or smaller. Let us assume that everything is shrunk. Thus an animal would still contain the same number of cells in its body. Also, each atom and molecule would shrink. Assumption: Physics has... (more) |

How does my aliens' tractor beam work in space? Researchers create a sonic tractor beam By Hanae Armitage 27 October 2015 1:00 pm Using a simple set of loudspeakers, scientists have figured out a way to levitate and rotate objects in midair. If perfected, this "sonic tractor beam" could find uses ranging from treating kidney ston... (more) |

Every now and again God puts us on pause. Can we detect this? Imagine that God has many universes to deal with or just needs a break sometimes. He has a pause control. What plausible mechanism does God use to perform the pause without breaking the laws of physics he has created? Is there anything in our current knowledge of physics that forbids a pause? What ...

TotalRewind™ (brain chip) In 2015 we can rewind the TV, our CCTV footage and, if we wear an action cam, our latest adventure. However if we walk down the street and something happens we didn't quite catch, the annoying fact is that there is no 'real-life' rewind. Background In the not-too-distant future anyone who can a...

Lego world. How do they reproduce? It is difficult to find statistics for the ratio of Lego men and women in the general population but from a non-scientific survey, I get the impression that Lego men vastly outnumber Lego women. Yet clearly they do reproduce. Here is a picture of a pregnant Lego woman. Setting aside the gender rat... (more) |

What is the best planetary orbit around a black hole in order to support life? Note: I am aware of a previous question Physiological effects of living on a world close to a black hole As I understand it, that question refers specifically to a planet that is in a non-ideal orbit for life, i.e. it is 'close' to its sun. I'm asking for a description of the optimum orbit for li... (more) |

Small universe - is there any point in interstellar communication? Everything on Earth and in the Solar system is as we know it. However it is discovered that we live in a small but unbounded universe. That is to say if we travel far enough in a straight line we will return to Earth. You may be familiar with the classic Asteroids game that can be played here. If yo... (more) |

The universe is in a long, slow decline to darkness (the stars are going out) - What can we do about it? The universe is in a long, slow decline to darkness Sorry folks but it's true, read the article! Here's a much edited-down version: The universe is cooling down, its stars pumping out about half as much energy as they did 2 billion years ago. From the birth of the first stars, nuclear fusio...

Dumbbell planet - how would humans cross the bridge? Note: I am aware of this question Could two planets be tidally locked to each other so close they share their atmosphere? My question is not about that. It is specifically about human travel. By a cosmic accident, Slartibartfast's design, or through God's will there is a planet that is shaped like... (more) |

Personal fart power - is it viable? It's the future and oil resources have run out. A scientist has suggested using personal fart power to meet our individual power needs. World governments are seriously considering this. They have identified a strain of genetically-modified bean that is easy to grow and results in an incredible degre... (more) |

Glass rot - could we survive it? In the near future on our own planet of Earth, an odd plague has descended from space. It affects glass. Any glass whether natural or man-made turns into powder. The chemical elements are the same, it's just like incredibly finely ground glass. Glassmakers can melt the powder and turn it back into ... (more) |

Where is the inside of the Tardis? Is it a world in itself? Is it part of a different world? The Doctor's TARDIS is larger on the inside than on the outside. How can this be achieved? The conventional answer is that The TARDIS is dimensionally transcendental ... the interior exists in a different, relative dimension to the exterior. http://www.thedoctorwhosite.co.uk/tardis/ Howe...

How would a species evolve in a world exclusively made of water? There is a cold planet (maybe a moon of a gas giant) far out in a solar system. It has a solid core and the surface is a thick layer of ice. Because of nuclear fission in the planet's core it is warm enough for there to be a huge ocean between the core and the ice. Enough gases and minerals bubble ... (more) |
