    201201The first factor is the light-crossing time:

    203 [[latex($t_{light} = \frac{r}{c} = 8 ~days $)]]
     203[[latex($t_{light} = \frac{r}{c} \approx 8.2 ~days $)]]
    204204
    205205The second factor is the ratio of the box radius to the mean free path. We set this to = 1 in our derivation above:
