Event Description

Titan’s atmospheric chemistry produces a host of discrete organic chemical products. It is likewise well known than Miller-Urey type reactions produce a host of complex discrete organic products. We have examined various complex reaction mixtures derived from various synthetic pathways and find a remarkable correspondence. This convergence of product mixtures may provide novel avenues for considering the ways life may emerge from disparate abiotic chemistries.

I asked the following at this live event.

Is there any hint of evidence either way that the organic molecules that led to life had a possibly celestial cold start, or alternatively, a relatively hot terrestrial beginning?


I was told that I'd asked a $64000 dollar question which according to Wikipedia means (I had no idea but hoped it meant a lot :-D),'' a common catchphrase for a particularly difficult question or problem.''


No, apparently we have no evidence either way was the answer. I'd wanted that confirmed as at another live NASA event some time prior I'd suggested building large area experiments to try and recreate the conditions that lead to life as the Miller Urey Experiment was very small scale. That idea have been readily agreed on when it was read out. Other live events at NASA and other institutions convinced me that a possible cold start for life should also be taken into account when building the later mentioned facilities


What I need to find out now, as a result of the new info I had confirmed, is whether it is easier for organic molecules to replicate in a cold to hot gradient or vice versa, thus backing argumentation for either scenario for the beginning of life

¿Are the Venusian sulphuric acid clouds the by product of long dead anoxogenic photosynthetic organisms?

Posted by Andrew Planet on May 4, 2020 at 2:51pm 2 Comments

I just read the piece at the link below entitled "Study: Life might survive, and thrive, in a hydrogen world."

I'd been thinking on similar lines recently, on different atmospheres with early life, but I was considering anoxogenic bacteria whose byproduct is sulfur instead of molecular oxygen. ¿Had life evolved on Venus could its sulfuric clouds be the signature byproduct of such life with no branches ever evolving to produce the equivalent of Earth's Great…

100 years tomorrow 26th April 2020 since we looked beyond the Milky Way Galaxy

Posted by Andrew Planet on April 25, 2020 at 11:10am 0 Comments

Exactly 100 years ago tomorrow, the subject on whether this Universe is larger than the Milky Way Galaxy was brought up publicly at an event sponsored by the National Academy of Sciences, known as The Great Debate. Until then the Milky Way was thought to be this Universe.  Conference at the NAS http://www.nasonline.org/about-nas/events/annual-meeting/nas157/
