How is the speed of light constant in all directions for all observers? Nevermind, I've updated my question notes with the Lorenz Transform. From this, it appears time observed at a point in space is warped according to the direction of relative travel. For example, at the time of the Pulse, BoxGuy's mirror is at $(d,0)$, which maps to PlatGirl's $(\frac{2\sqrt{3}}{3}d, \frac{\sqrt{3}}{3}d/c)$. Thus, PlatGirl observes a current version of BoxGuy (for them both), but BoxGuy's "current" mirror is a future version of PlatGirl's "current" mirror. By symmetry, if the mirror and origin were reversed, PlatGirl's mirror would be the "future" one. Is this correct? |

How is the speed of light constant in all directions for all observers? Ok, so we set the space-time-origin (0,0) to Pulse at the Light for both BoxGuy and PlatGirl. The space-origin "moves" with the Light for BoxGuy, but is fixed relative to the platform for PlatGirl. At (d,d/c) and (0, 2d/c) for BoxGuy, Reflect and Return happen respectively. What is the formula for translating these space-time coordinates directly back to PlatGirl's coordinate system? |

Acceleration of two falling objects with identical form and air drag but different masses @MarkEichenlaub: That is true when air resistance is the driving force (e.g. The balloon is moving upwards at close to or past its terminal velocity speed), but that is not the case when the balloon is moving upwards at slower speeds (where gravity is the driving force). I have added this clarification to my answer. |
