Summary:
- All living organisms, including plants, animals, and even humans, emit a very weak light that is invisible to the naked eye. This light is called biophoton emission or ultra-weak photon emission.
- The intensity of this light decreases after an organism dies, as the biological processes that produce the light slowly stop. This can be used to determine when an organism has died.
- Studying biophoton emission can provide insights into the fundamental life processes of living things and may have applications in fields like forensics, medicine, and ecology.
