Until we actually get samples we can't prove beyond any doubt that there is any similarity between Earth's oceans and these frozen moons. And even if we could prove that there are water oceans there that still doesn't prove that life could have developed there since we still don't understand exactly how life came to form on Earth yet either. But it certainly is an exciting and plausible theory.
First, hypotheses don't have to be accurate, they're hypotheses! It's an educated guess based on information gathered to date and it is something to test, not declare! The point of a hypothesis is to have something to prove or disprove. It feels like the common colloquial use of hypothesis is as something that's been proven and is taken for a fact... and that couldn't be further from the truth! The hypothesis is where you start your inquiry.
With that said, it's interesting because it seems there are more similarities between Earth's deep ocean environments and Enceladus' from what we can see so far.
I'm not saying we're going to find life, I'm saying (and I believe what the paper is saying) is that from what we've found so far, the chances of finding life in Enceladus' deep ocean are now much higher than we previously thought due to that unexpected similarity.
Also, we do know that Enceladus has a salty water ocean
, Cassini found that for us as well as finding the molecular hydrogen
in the plumes. And just because we don't know exactly how life started on Earth (which there are a few good hypotheses) doesn't mean we can't find out how or why life got started on another celestial body. Why would you think knowledge about Enceladus (or any other moon, planet, or planetoid) hinges completely on our knowledge of Earth?Edited by LazarusIV - 4/17/17 at 9:03am
