| Jan 21, 2017 at 22:55 | comment | added | pablodf76 | @Zxyrra I'd prefer if it evolved naturally. But in fact I'd consider the possibility of little or no sunlight to begin with (think a rogue planet or something like Planet Nine, way out from the Sun). | |
| Jan 21, 2017 at 22:47 | comment | added | Zxyrra | Does the organism need to evolve, or can it have been designed in a lab and then put into place? It may not evolve to feed off of cosmic radiation when there's regular sunlight but it's possible that an engineered organism could make use of it | |
| Jan 21, 2017 at 22:03 | comment | added | pablodf76 | @Karl I guess that must be so, but do you have figures on that? On Wikipedia it says that "cosmic ray energy density averages ~1 eV/cm³" (which is indeed minute), yet it also says that Earth gets ~10⁴ particles of avg 10⁹ GeV per second per square meter (and presumably many more at lower energies). Am I missing something? | |
| Jan 21, 2017 at 21:40 | comment | added | Karl | The overall energy flux of cosmic radiation is minute, while the energy of a single "cosmic rays" is far too big to be useable by any chemical process. | |
