Shockwave synthesis.

The problem is that life is a state of matter with less entropy than non-life. But entropy increases over time. So how do we get to a state with less entropy?

What most people don't know: The laws of thermodynamics are only valid in a thermodynamic equilibrium. Systems out of equilibrium move towards that equilibrium with a certain speed. But if you change things so fast that the system cannot go to equilibrium, it's possible to break the laws of thermodynamics.

During shockwave-synthesis you have soundwaves travelling through e.g. a chemical solution. If the frequency is high enough (e.g. from a really short, really strong event, e.g. an impact), molecules can do chemical reactions while not being in thermodynamic equilibrium with the rest of the liquid.

With this, it's possible for simple molecules to react to complicated molecules.

A current theory is that a meteorite impacted on Earth and that this impact synthesized the first building-blocks of life.





If these complicated molecules happen to find other complicated molecules that in combination enable chemical processes that keep these molecules intact and even enable the synthesis of more identical molecules, then you have life.
