The thing is that some people believe that the windows of heaven is an astronomical repulsive force and as the windows open the force increases.
They reckon the force changes time so that in the time of the flood the windows of heaven caused time to pass faster so as they opened up to billions of years passed by in 5 months.

If it happens whilst God opening the window then how come the flood on cleared when he stopped them? Why are people looking for ways to explain the flood?
It seems pretty obvious to me that God has a channel where an abundance of anything can be passed to earth.
