I do not see that there is actual evidence here for this speculation.
However we also know that another researcher froze some organic
precursors for twenty years and did get encouragement. The fact
remains that we are just breaking into slow cold chemistry to see
where it all takes us and right now we can expect surprises.
Thus brinicles become interesting if we can set up a stable
experimental system that uses them. They are the cold water analog
of the volcanic hot spring.
It is all suggestive for now.
Sea stalactites
provide clues to origin of life

Life on Earth may have
originated not in warm tropical seas, but with weird tubes of ice -
sometimes called "sea stalactites" - that grow downward
into cold seawater near the Earth's poles, scientists are reporting.
Their article on these
"brinicles" appears in ACS' journal Langmuir.
Bruno Escribano and
colleagues explain that scientists know surprisingly little about
brinicles, which are hollow tubes of ice that can grow to several
yards in length around streamers of cold seawater under pack ice.
That's because
brinicles are difficult to study. The scientists set out to gather
more information on the topic with an analysis of the growth process
of brinicles.
They are shown to be
analogous to a "chemical garden," a standby demonstration
in chemistry classes and children's chemistry sets, in which tubes
grow upward from metal salts dropped into silicate solution. But
brinicles grow downward from the bottom of the ice pack.
The analysis
concluded that brinicles provide an environment that could well have
fostered the emergence of life on Earth billions of years ago, and
could have done so on other planets.
"Beyond Earth,
the brinicle formation mechanism may be important in the context of
planets and moons with ice-covered oceans," the report states,
citing in particular two moons of Jupiter named Ganymede and
Callisto.
Billions of years ago?
ReplyDeleteHow large would the sun have been back then? Scientists ALSO tell us hat the sun is shrinking a little every year.
So, billions of years ago the sun would have been large enough to fry every thing in our solar system.
Trying to say that creation came from nothing & no outside force acted on the very 1st matter of the 'big bang' takes a LOT of faith.
How did the so called 1st cell know what to do next? How did the cell know how to divide? How to create DNA & include it in the process? Or is DN another 'miracle' accident?
Though I don't claim to know or understand it all, I am sticking with Nature's God as the Creator.
He takes a lot less faith to believe in.
Thank you.
