Oxygen is created in stars and dispersed in supernova explosions. It then mixes with hydrogen in clouds of dust and gas out in space and forms water. (Had to look it up :)
Re: “It then mixes with hydrogen in clouds of dust and gas out in space and forms water.”
There needs to be an energy source for fusion.
I can’t figure out where the energy comes from.
From inside the planets when they form?
From super heated gases caused by star death?
Just about every element on the Periodic Table is created in stars. The iron in our blood for instance.
This is along my line of thinking, water is probably very common in the universe.
Thanks to everyone who helped wash away my misconceptions about the genesis of water.
And thanks for reminding me that “fusion” is absolutely the wrong word (and concept) when applied to molecules.
I read through every link that each of you provided.
I am still struggling with one part of the explanation.
If I understand correctly, H and O become H2O while they are still both super chilled, micron sized solids.
That is a very difficult concept to understand, especially since there does not appear to be any external heat or pressure involved in the transition.
