  • Is there something explicitly limiting the speed of light?

    speed_of_light
    If I’m travelling at 50mph and throw something forwards at 50mph then you can add the 2 speeds to see that the object is going at 100mph. However, light does not behave that way. The light that leaves me when I’m stationary goes the same speed as when I’m moving. Imagine a head-on collision seen […]

  • The geometry of space-time

    GPB_circling_earth
    We have determined how to translate coordinates between two observers in relative motion, and this tells us that the speed of light is a) finite, and b) the same for every observer, regardless of their relative motion. It has nothing to do with that. I am talking about the effect happening before the thing that […]

  • Accepting E=m*c^2

    e=mc2
    I am hardly afraid to touch black holes; I don’t feel any more time should be wasted on them than already has been. That “artillery officer” you mention is none other than Pierre-Simon Laplace; in fact, he was simply an examiner at the (French) Royal Artillery Corps, appointed because of his prior academic achievements. He […]
