Does glass get stronger the longer its under water? @DavidZaslavsky it should be up to the OP, really. The answers would be cleaned apart from the top one. |

Maxwell's Correction to Ampere's Law Can you be more specific? You spend a lot of time explaining the parts you do understand, but are not very clear in what you need to know... |

Why are Navier-Stokes equations needed? Why would we need that much air to have turbulence? You should mention the minimum amount where NS equations are relevant. |

Vacuum energy and perpetual motion Maybe it's worth noting that the "spacetime regions that are very small" are actually galaxy size :-) |

Age of universe estimates @ipavlic I wouldn't be so sure: a lot of algebra and analysis have extremely close ties with geometry - e.g. you can calculate the equation of the line joining any two points via algebra. You can find such a line via a limit and so on... Thus, there would be counterexamples to proven theorems such that R is complete etc. |

Age of universe estimates I haven't thought this throug but is it possible that (eventually) changing physical laws "disprove" conservation of energy because of noether's theorem? |

Age of universe estimates @RonMaimon one could say it's "as reasonable as YEC" - which was precisely my point. The tricky bit is explaining to the OP how unreasonable that is :-) |

Is the EmDrive, or “Relativity Drive” possible? This belongs on Physics and it's very unlikely to get a decent answer here, in my opinion. Do you want me to migrate? |

What really allows airplanes to fly? @MikeDunlavey we are in violent agreement... :-) |

What really allows airplanes to fly? @MikeDunlavey the angle of attack is key, remember that airplanes are known to fly upside down (thus implying that the geometrical configuration of the wing can be reversible). |

How can we know, today, that there's something from 100 light-years from here? Note that the distance is irrelevant, we can only measure the past. The present is an illusion, if you think of it. |

Superluminal neutrinos @Alain I am a bit confused: if the clocks are in sync, the time measurement does not depend on the GPS movement. Or are you talking about the distance measurement (which is done once)? |

Superluminal neutrinos I watched the original presentation of the results, and they say specifically that the clocks are originally synced by using a portable atomic clock, twinned with the ones in the satellites. So this allows for a very strict (original) sync without relying on GPS directly. They further said that each site syncs with the GPS clocks to keep the two sites with max ~1ns difference. So I as far as I see, it would be very hard for the clocks to go out by 60ns. Finally GPS is used to find the site's positions. But these are two independent measurements. |

What would be the effects on theoretical physics if neutrinos go faster than light? @RonMaimon "when something crosses a threshhold of plausibility, it is impossible to say what the implications are." -- if you cannot give an answer then don't. Leave a comment saying "this is unanswerable, because...". Use the answer box just for answers. |

Superluminal neutrinos @Lagerbaer I think the trajectory is all underground... it starts in a deep tunnel at CERN and ends under a mountain at Gran Sasso :-) |

Common false beliefs in Physics @KimKim I didn't express myself properly: I've seen people believing that. |

Superluminal neutrinos You would still need to explain why a massive particle (the neutrino) moves faster than a massless particle (the photon). |

How bright can we make a sun jar? @ene thanks, fixed. |

Does the “Energy Catalyzer” generate energy by converting Nickel to Copper? Moved this off to physics, as it's better suited there. |
