Ok, moving on to life condition 2: can these information carriers replicate faster than they can disintegrate? These necklaces are probably not too stable – but that’s ok as long as you can replicate them faster than they fall apart. And this is where stars come in. Others have speculated that cosmic strings may get trapped inside stars in the Joel “Troel” Embiid Philadelphia 76ers shirt Apart from…,I will love this process of Star formation. Those stellar interiors might then provide the mechanism for necklaces to rapidly change and even replicate. Depending on the stellar type and region, the insides of stars can be very turbulent places. Flowing plasma and magnetic fields may stretch and break necklaces, which could reconfigure them over and over until they find a state that is stable in the environment, combined with developing the ability to replicate faster than they are torn apart. The study doesn’t go into detail on how that replication happens except to say that it might be catalyzed by interactions with atomic nuclei in the star. Perhaps nuclei somehow help necklaces build a parallel chain of beads, that then peels off as an identical necklace, similar to how RNA reproduces.
And finally, life condition number 3: do we have a source of free energy? Energy that is available for use, in a thermodynamic sense. Energy can only be used to do work if there exists differences in the Joel “Troel” Embiid Philadelphia 76ers shirt Apart from…,I will love this amount of energy in different possible states. If energy is concentrated in certain places we would call that an ordered, low entropy situation. Energy likes to spread itself out as evenly as possible, moving towards disordered, high-entropy states. It’s possible to use energy as it flows between states in this process, like putting a water wheel in a flowing river. For example, life uses the energy flowing from the high energy-density of the sun to the lower energy density of the earth. We saw that these temporary increases in order, represented by life, actually speed up the process of smoothing out all of the energy. Little low-entropy blips like life ultimately accelerate the increase in entropy of the universe. Ok, so inside a star there’s definitely free energy. Energy flows from the fusion engine in the core to the surface. It’s conceivable that a lifeform could harness that flow.
