Why Does it Rain?
In grade school we were taught how temperature, dew point and moisture in a cloud could condense around a tiny ice crystal to form a drop of rain. But scientists are not really all that sure how raindrops form.
The problem is that the particles of mist in the cloud are all negatively charged. Since their charges are all the same, mist particles don't attract one another; they repel one another so it should never rain.
Some scientists have suggested that radioactive radon gas is responsible for changing this state of affairs in the cloud so that rain is formed. As the radon decays, absorbed by the droplets, it adds a positive charge to them. Because their charges are different than the surrounding negatively charged droplets, they begin to attract each other and soon the droplet has become large enough to fall as a raindrop. Unsure of this theory, other scientists are staying with the ice crystal theory.
Modern science often offers its conclusions with a very sure-sounding voice. But the fact is, scientists are unsure of many things, including the simple problem of why it rains. That's why we shouldn't get too worried when some scientist claims to have discovered something which he says proves the Bible to be in error.
