#404 โ€“ Lee Cronin: Controversial Nature Paper on Evolution of Life and Universe

Oxygen, availability, all this stuff. And that then allows us to focus in our chemistry. So when a chemist does a reaction, that's a really nice compressed shorthand for constraint application. Glass flask.

pure reagent temperature pressure boom boom boom boom boom control control control control control so of course we have bond energies this so the bond energies are kind of intrinsic in a vacuum if you say that so the bond energy you have to have a bond and so for assembly theory to work you have to have a bond which means that bond has to give the molecule certain laugh a half-life

So you're probably going to find later on that some bonds are weaker and that you are going to miss in mass spectra. When you look at the assembly of some molecules, you're going to miscount the assembly of the molecule because it falls apart too quickly because the bonds just fall. But you can solve that with looking at infrared.

So when people think about the probability, they're kind of misunderstanding. Assembly theory says nothing about the chemistry. Because chemistry is chemistry and their constraints are put in by biology. There was no chemist on the origin of life, unless you believe in the chemist in the sky. And they were, you know, it's like Santa Claus. They had a lot of work to do.

Exactly. The grammar of chemistry, of course, emerges in reactions, and we can use them reliably, but I do not think the Wittig reaction is accessible on Venus.

Everyone is grumpy on some days when you challenge. The problem with this paper is it's almost like I went to a party. I used to do this occasionally when I was young. Go to a meeting. and just find a way to offend everyone at the meeting simultaneously. Even the factions that don't like each other, they're all unified in their hatred of you just offending them.
