Hi!
I think most of us are familiar to this paradox which solved a mystery and expresses in indirect speech that the night sky will be even brighter and brighter through time(why do you think?!)its idea is a real powerful one!
I have a question of that!If the night sky supposed not to be dark some day in future,how long do you think it takes for it to be as bright as the day sky?!
In the other hand,would you find an equation for the rate of decreasing the mean magnitude of night sky over time?mean dm\dt?!
let's find out:thumbsup:

if we figure out how long it took for it to be as bright as it is now... since it was...umm dark...maybe it'll be a little hint:P
