I did ponder that years ago.
Curious that it took so long for them to figure it out.
The comet theory always struck me as lazy.
It would have taken million and millions of comets to fill the oceans....................
Yeah, me too. I can’t imagine how many unlucky comets it would take to equal the water on this planet. When I took Chemistry in high school, we had a week-long session on how to construct a filter to get pure water. On the exam the next week, the teacher asked us how to get pure water. I was suppose to construct this elaborate filter, but instead I said: “Burn hydrogen.” The teacher was visibly PO’ed, but gave me full credit.
That it was unlikely to yield the consequent mass is also concerning, especially under solar bombardment.
Yet if I recall, they had stats and logical arguments that supported icy meteorites ocean formation hypothesis as well.
From what I dimly remember is they can tell the meteorite composition by looking at its spectra as it falls through the atmosphere , heats and becomes incandescent. Many of them are made of all or partly frozen water.
Then they used math… number per year falling x so many billion years x estimated mass average= total water. And it was a LOT.
Maybe both theories are valid?
Like the "fossil fuel" from dinosaurs and plants theory. Except it doesn't explain Titan's methane lakes. Now they can go figure out how all that crude oil got in the ground and is more being made every day.
Agreed, you have hydrogen and oxygen so is it so far fetched to believe there is a mechanism to make water from that
Like wise the idea that oil comes from decaying organic matter never made sense to me, coal maybe, but not oil in the quantity it exists ans the depths it is found
Lakes of hydrocarbons on Jupiter’s moon, from dead dinosaurs😂
“The comet theory always struck me as lazy.”
It was pretty clever, actually. But spend some time in the Pacific and then ask yourself how many comets that would take, even over billions of years. That ocean is DAMN BIG.
