Nice video. Here's another as one potential answer to your question: The way you make the incredible machinery of the modern cell is with slightly less complex machinery in slightly older cells, all the way back to the very simple machinery of the oldest cells. Sort of obvious really... Friend: "With what?" Edited by cavediver, : No reason given.

Incorrect - 1LoT is simply an observation of the effect of the principles of statistical mechanics acting in a flat background space-time. They, and the 1LoT are inapplicable in the form you are implying in the region of the T=0 point in Big Bang cosmology space-time.
Incorrect - matter is being created and destroyed at every point of the Universe every moment of time.
Incorrect - matter fields are constantly creating and destroying quanta of matter. See above.
Incorrect - we see this process every day in the particle accelerators in use around the world. You may be thinking of energy?
Nope... Apologies for the OT reply - back to the topic at hand Edited by cavediver, : No reason given.

I don't think "failed" as that was not his intent. Perhaps we could follow on from his work and look at potential pathways that could lead to the DNA machinery. But first, I take it that you agree that self-replicating protocells could arise in this manner?

Could you please then explain the processes of pair creation and pair annihilation? That is where two photons (not matter) combine to create an electron and a positron (both matter), and the reverse process where two particles of matter annihilate to give two photons (commonly referred to as matter/anti-matter annihilation)
Actually, I can

Oh dear, then I think my old students are in trouble I think both you and PhysicalGeography.net need to learn some definitions, and some advanced physics...
No, it is a creation. That is why we call it "pair creation". Edited by cavediver, : No reason given.

We've already seen that, in the video we showed you. The question is, can we progress from the rudimentary genetic material of the protocell to RNA/DNA?

And just so you know, not even energy is conserved in all cases - but that's a topic for bigger boys...
Oh thank Allah for Christians who can show us physicists where we're going wrong You're a hoot Edited by cavediver, : You'd think I could spell physicist

By when did scientists have to produce life in a lab before supernatural creation became the only option left? Was it 50 years ago, 10 years ago, or just yesterday? In the same way, how long did primative culture have to come up with an explanation for lightning, before supernatural act became the only option left?

So, IF we have a scientifically plausible scenario for the creation of the first proto-cells, and potential pathways as to how those proto-cells became the first cells - BUT, we have no proof as to whether this scenario is actually true, THEN is a supernatural creation still the only real option?

No, he didn't. Ever. Edited by cavediver, : No reason given.

Given that you have ignored every difficult question posed to you, it's not going to make much difference

Huh? What do you think those polymers are? They are the proto-proteins. And in the video, you can see the early mechanism for replication. The amazing thing is that the early polymers were just random chemicals with no relation to the lipid vesicles that contained them. But evolution kicks in even at this exceptionally early stage, and "useful" polymers, from the perspective of replicating vesicles, simply dominate. Mind-blowing in its simplicity and implication.

It's quite possible that it does happen, but you have to remember that these locations are already teaming with unicellular life, and anything and everything is regarded as food! The one thing that abiogenesis had going for it was the complete lack of active predators Now, I'm no chemist, but it is also entirely possible that the environmental conditions that were favourable for the development of the lipid vesicles (pH, minerals, organic content, gas concentrations, etc) are not now generally observed - owing to both the vastly different atmospheric conditions, and the post-abiogenetic abundance of life.

How does the above question score a message rating of 2??? It's a good job that rating is anonymous 'cos I'd hate to look THAT stupid... Edited by cavediver, : No reason given.
