In response to "The gun WAS off to the side. now it makes a sound directly behind each runner." by loosilu

Yes, but the light being emitted from the gun is still only coming from the side, and since light is roughly 88,000 times faster than sound it gets there first.

- If Usain Bolt wins by .00000002 seconds we'll know who to blame! -- nm - Ender Aug 3, 13:24 9
  - they clearly have to make the lanes farthest from the gun, a couple of nanometres shorter -- nm - zork Aug 3, 13:37 1
    - Hmm, if they run north-to-south that might be accommodated by increased expansion due to the western lanes having been exposed to the sun slightly longer... -- nm - Ender Aug 3, 13:42
  - Are we also accounting for the Corilolis Effect? - Reagen Aug 3, 13:25 6
    - The 100m track runs north/south so they'd all be affected equally. -- nm - Ender Aug 3, 13:27 5
      - but they're all on slightly different latitude lines. -- nm - Reagen Aug 3, 13:29 4
        
        (throughout the race) -- nm - Reagen Aug 3, 13:30 3
        
        Well, that's their own fault for not running faster. They all start at the same spot (within a few mm at least). -- nm - Ender Aug 3, 13:32 2
        
        this was the point I was about to make. the start and finish lines are not *exactly* 100m nor exactly parallel. - zork Aug 3, 13:35 1
        
        do left handed athletes have an advantage in the southern hemisphere? -- nm - zeitgeist Aug 3, 13:58
