The paper touches on a few key points:
- There are many worlds with life in our own galaxy (billions), or least worlds capable of hosting life.
- The work of Jeremy England confirms that life emerges/evolves in/as dissipative systems, ie life emerging goes hand in hand with the evolution of a cooling star, which is a dissipative system, (ie thermodynamically open system, not in equilibrium with its environment) life adapts/changes to make the best use of the energy in its environment, it has to because it is in a dissipative system, it can not change in a closed system, or differently said, life needs a dissipative system in order to arise and adapt.
- With stellar metamorphosis we have a large sphere with different layers (clines), where different types of life reside in different layers, while shrinking the layers begin to mix, and different types of life comes into contact which each other, i point out that this is the mechanism by which more complex life emerges.
- Life is probably inevitable
Final remark: I think these insights really take our understanding about life in this Universe further. I was glad Jeffrey called it a 'leap' in his youtube video he did on the life paradigm paper > link > [www.youtube.com]
