Earth's Water

Postby elguapo » Tue Sep 04, 2018 12:22 am

Scientist have speculated as to how the Earth got it's oceans. The most popular theory is that Earth got bombarded with icy asteroids and that ice become our oceans. But have you looked out into the ocean and said "that's a lot of water" and wondered how many icy asteroids it would have taken to fill the oceans? If that's the case then why does Venus and Mars barely have any water? Those planets surely got bombarded with icy asteroids too right?

Scientist also say that icy bodies form in the outer regions of the solar system because the sun's heat vaporizes the ice. One of Jupiter's icy moon is said to have the same water composition as our oceans.

When Jupiter formed it started falling towards the sun until the outer gas giants gravity started pulling Jupiter out again. What if Earth was one of Jupiter's icy moons that was left behind in a tug of war with the Sun when Jupiter started heading out ward again? What if all that ice melted to give us the oceans we have today?

Well, there's a lot of evidence that Mars once did have oceans, but they eventually dried up. Venus may have had them as well, but it's too close to the sun for them to survive now.

Are there any research papers or articles on this hypothesis, or is it and idea of your own creation?

I'm not sure about Earth being a moon of Jupiter, but considering Jupiter's immense gravitational pull, I wouldn't be shocked if the collision that created the moon was caused by big rocks being flung out from Jupiter's orbit.

I KNOW how, I just won't say because it is based on my religion...

I don't know if that's "knowing". I've felt that "knowing" and "believing" are different. When I was a churchgoer, I always got annoyed when fellow churchgoers would say that they "knew beyond a shadow of a doubt". I've always been a person who needs evidence.

Granted, when I was religious, I still believed that the earth was created 4.5 billion years ago. I just believed that the creation of the universe--the big bang and all that--was guided by the hand of a higher power.
