    The turning points question on measuring light speed.. Anyone do distance over time?
    Other than that it was fine, some answers i got:
    24V
    11m
    250 muons
    First box
    4.69x10^5V
    Yep same... Where was 11m ???

    Surely you would add 1 to 2.57 AU? The max distance is going to be when the earth and asteroid are aligned and at either side of the sun?
    Yeah that's correct

    Yep you add the distances because maximum distance is when earth is on opposite side of the vestra(?) asteroid.
    Something like 3.57AU
