Science has discovered that the two seas - salt and sweet water - cannot mix. Due to diffrences in salinity, density and oxygen the seas cannot cross eachothers. This information has been discovered using advacned equipment for measuring these valuables. The Quran also speaks of a separation line between sweet and salt water, and the fact that these waters cannot blend. ''And He is The One who has flowed two waters, one sweet and the other salt, and between them separation and a barrier. (Quran 25:53)
