    wow

    Keep it up and you'll be the next on the list!
  2. It basically comes down to it's thrust to drag efficiency. It reaches a speed where the drag equals the thrust. Since the apparent wind is shifting further and further forward it is harder and harder to gain thrust to match the increasing drag (mostly aerodynamic drag on an iceboat) inspite of the increase in available energy. Due to the efficiency of the iceboat this can still come at over twice the wind speed.
  3. The tree was beaten by Yourdad by 2 minutes edit: only 9,993 to go!
  4. There should be an almost negligible time dilation/increased lifespan caused by the increased velocities and accelerations, if no other effects overwhelm it.
  5. Or oppositely (albeit lacking gravity not antigravity) the crater itself would create an anomaly at the projected "surface" (average radius) compared to what it would be if the crater didn't exist or was filled with moon dust.
  6. deduct the apparent wind vector from the true wind vector and you get the boat speed (velocity) vector.
  7. So a capacitor is a pair (or more) of oppositely charged conductors. I had it pictured as a single charged (positive or negative) conductor. So either pole won't discharge to ground due to the proximity and opposite charge on the other?
  8. A capacitor with an electrostatic charge can kill, although it is the current it creates that is lethal.
  9. What does current theory say about this? If everything in the universe was, on average, rotating would a foucault pendulum be dragged around with it or not? If gravity and inertia are locked in step the way they appear, doesn,t the mass distribution and movement effect both inertia and gravity and through the same means? I don't know if this is right, but I think this is basically mach's idea. If this is not right then is space somewhat independant of mass?
  10. If it's massive enough he can cross the event horizon without feeling anything (small tidal effect), though his fate is sealed.
  11. So is the station in Brazil moving through space...or the one in China?
  12. Equal densities and same shape and the bigger one should land first. I'm assuming the drag coefficient is the same but frontal area is not increasing proportionally as much as mass.
  13. No If they are the same shape and density the 1 tonne weight hits first. I think the law is reckless endangerment and you go to jail.
  14. You extrapolate back anywhere close to the Big Bang and you've already strayed somewhere. Just my overpriced 2 cents worth.
  15. If it is perfectly rigid and frictionless an infinite force is produced horizontally.
  16. As a third choice he could spin on his own axis and hope his calculations compensate for it.
  17. Which in their reference frame is the same position. So they don't think (do the math), they just aim and shoot.
