Would neutrinosynthesis be physically possible for a lifeform to have?

Click For Summary

Discussion Overview

The discussion explores the hypothetical concept of neutrinosynthesis, questioning whether a lifeform could evolve to utilize neutrinos as an energy source. The scope includes theoretical considerations about biological adaptation and the physical properties of neutrinos.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that if neutrinos are ubiquitous, it might be possible for an organism to evolve a method of neutrinosynthesis.
  • Others argue that for neutrinosynthesis to occur, an organism would need to detect, interact with, and extract energy from neutrinos, which poses significant challenges due to the weak interaction of neutrinos with matter.
  • One participant suggests that unless the neutrino flux is extremely high, interactions would be too rare to serve as a viable energy source for lifeforms.
  • Another participant questions the nature of energy released from neutrino interactions, indicating uncertainty about whether it could provide usable energy for a lifeform.
  • A later reply emphasizes the need for understanding the reaction cross-section of neutrinos with ordinary matter, suggesting that the idea of neutrinosynthesis may not be feasible.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of neutrinosynthesis, with no consensus reached regarding its possibility or the mechanisms required for it.

Contextual Notes

Limitations include the speculative nature of the discussion and the dependence on the understanding of neutrino interactions, which are characterized by extremely small reaction cross-sections with ordinary matter.

It's fascinating how all photosynthesis (the food of plants) requires is sunlight. If neutrinos are everywhere, could neutrinosynthesis be possible if an organism evolved to have it? Or are they too simple to have an appreciable effect on a lifeform?

You would first have to figure out how/if they could
  • detect it
  • interact with it
  • extract energy from it.

I don't mean consciously; I mean they would need to have some organ or molecule that would stop/absorb neutrinos before they could leverage it for any purpose.

Neutrinos are notoriously ephemeral. They pass through planets; what could a critter - who is, after all, made of planet stuff - do about it?
 
Unless the neutrino flux is so absurdly high that interactions between neutrinos and the organism happens on a regular basis, i.e. thousands of times a second, I don’t see it being a viable energy source. And if your neutrino flux is that high, then you probably have way bigger problems. 🤣

Aside from that, what’s the type of energy released by a neutrino interacting with something? A flash of ultra faint light? A burst of radiation and particles? I don’t remember off the top of my head but I don’t think it’s a viable energy source for a life form.

So please read more about neutrinos and their reaction cross-section with ordinary matter (extremely small). Once you do that reading, I think you will understand why your speculative idea could not work. This thread is closed for now because of the speculation. Keep asking good questions, but only after you have done the searching and reading of technical articles. Thanks :smile:
