"Why we might be alone" Public Lecture by Prof David Kipping

And can we do that in a lab or does it take a whole planet to make that self-replicating chemical cycle?

I can cite several other somewhat similar self-replicating processes.

When a chlorine molecule destroys an ozone molecule the process releases a new chlorine molecule which then can destroy another ozone molecule, etc. This is why it took 30 years after chlorine-based propellants were prohibited, for the atmosphere to cleanse itself from these destructive ozone-depleting chemicals.

In a way that is almost like a destructive self-replicating cycle.

And at what point do you believe abiogenesis happened? Something magical or something natural?

I have been wondering if mitosis is a self-replicating process like the Krebs cycle. It is a faithful copying of DNA, which is a polymer of non-living bio-chemicals, and the process results in a self-replication of the mother cell, no?
