Could light travel more slowly than the “universal speed limit”? Could this imply quantization of spacetime? discontinuity in the range of possible velocities. Would that perhaps mean that spacetime is quantized? (I'm not sure that I'm being any clearer . . .) |

Could light travel more slowly than the “universal speed limit”? Could this imply quantization of spacetime? @RetardedPotential: If all of an object's motion through spacetime is devoted to moving through space, it seems like that object wouldn't move at all through time. Light, however, does move through time (maybe?), so it must not be devoting all of it's motion through spacetime to moving through space. Therefore, the "constant speed" at which everything moves through spacetime would seem to be faster than the speed of light in some sense. If there are no possible headings through spacetime that make an object move through space faster than light, it would seem that there is a (continued) |

Could much of the “missing” antimatter make up neutrons? That is what I meant by "negatron". |

Magnetic fields and gravitational waves. How far do they reach? @Raindrop: If I understand correctly, if a force's gauge particle is massless then its extent is (maybe?) infinite but if its gauge particle has mass then its extent is bounded. I think the strong and weak forces have gauge particles with mass. |

How is wavefunction probability redistributed after partial wavefunction collapse? Yes, I meant that the beamsplitter would still be present but without the camera off to the left. Just to be absolutely clear, would having no camera off to the left give the same interference pattern that having a camera off to the left would give (assuming the presence of the beamsplitter in both cases)? Thanks for spending time on this question. |

How is wavefunction probability redistributed after partial wavefunction collapse? Does this mean that the pattern observed at CCC would not be affected by whether C is present or not? |

Does Newtonian mechanics predict the bending of the course of light by objects with mass? Hmmm . . . it seems you did interpret it literally. My bad. |

Does Newtonian mechanics predict the bending of the course of light by objects with mass? You might also be able to say (at least if gravitational mass and inertial mass are assumed to be the same thing) that the Newtonian equation modeling gravity predicts bending of space . . . |

Does Newtonian mechanics predict the bending of the course of light by objects with mass? If we interpret "Newtonian" very literally, you might say that light is made up of particles. |

List of physics paradoxes What do you mean by "terrible consequences"? Do you mean it would imply current theories are incorrect? That the Earth would be destroyed? That someone would lose tenure? |

Are there any Earth-Meteorites on Earth? One hypothetical way this could happen might be for the meteorite to slingshot around the sun (think Apollo 13 slingshotting around the moon) to get heading back in the right direction. Does anyone know if this could happen? |

Do objects with mass “suck in” spacetime? So, if the GTR is correct, would that make it seems unlikely that gravitons exist? (Should that be a separate question?) |

Does the mass of an object change as it moves away from the earth? @voix: If the energy used to lift the plate above the Earth came from the Earth-plate system as it was before the lifting occurred (say, from fossil fuel), would the mass of the Earth-plate system be the same after the lifting as it was before? |

Does Newtonian mechanics predict the bending of the course of light by objects with mass? Would it work to say that you want to talk about Newtonian mechanics and the quantum theory of light? |

What counts as a measurement? The concept of "macroscopic" is kind of fuzzy and arbitrary. It seems like it shouldn't be relevant to what is measurement and what is not. |

Does the mass of an object change as it moves away from the earth? Do you have any sources or justification for why this is? |

Does the mass of an object change as it moves away from the earth? I wasn't meaning that sort of increase in mass, though I guess my questions doesn't indicate that. I'll edit my question to specify what I mean. |
