From where on Earth came the water?
The fact that water is very ancient origin is already an indisputable fact and scientists this fact has already resigned. Now there are ongoing debates about the place of origin of the "mysterious water". There is an assumption that somewhere far away in space when in the past there was a nebula in which the substances in vacuum were crystals of water, it was here and now, but until that time, birth of our Sun! To be a little more precise, it is a period of approximately 4.6 billion years ago.
If this theory is true, it turns out that water had appeared before the Sun and we drink the liquid that is older than our star house "the Solar system". As ice particles in the dust of the nebula remained intact and has not entered into a reaction, is still a mystery, but the fact that a lot of water still gets on the Ground it is an undeniable fact and this no one is going to argue.
Scientists had studied samples of water in the oceans in different places and at different depths and on a mathematical model looked at the epoch when this part of the galaxy or anything else really existed.
There is ordinary water, heavy water, water in the conventional sense very much, but deuterium is not too little, as it turns out. In the molecule of heavy water contains heavy hydrogen with an atomic mass of 2. This is a complex element consisting of a proton and neutron.
Water of this type is found in deep space, it is possible and on the satellites and on distant planets and perhaps even somewhere where we do not even suspect about its presence.
If and when the water appeared, she had appeared in some of the nebula and from there scattered throughout the neighborhood. Then came the Solar system. Blocks of ice could easily fly to any planet in the Solar system, just at the dawn of the. And in this case they of course may be older than the Solar system.
Scientists have found ancient ice on the moon and on the Earth and at the poles of mercury and Mars. If she is there and here, it is in a bottle of soda water, in a small amount but there is!
So the water got to Earth in the form of a piece of ice like it usually gets into your whisky glass in the form of a piece of ice!
