    The light of someone's life might not be just another person, but light in the literal sense. According to a recent study by researchers from University of Calgary, every living system emits light without requiring external excitation due to a biological phenomenon known as ultraweak photon emission (UPE).

      A long time ago scientists thought that they had managed to weigh a person’s “soul” when they put a corpse on a scale and the weight changed after death. It was actually the weight of the breath exiting the body, but I think this time it’s safe to say that this is definitely your soul glowing

        It’s just inefficiencies in your cells’ processing of energy being released as light.

          Yeah, isn’t it basically blackbody radiation? We’re warm so we glow

            Living things emitting Infrared radiation? Never heard of it.

            Though I want to say singlet oxygen reactions let off light in the red part of the spectrum.

            No, because the control was a non-living body at the same temperature, and blackbody radiation is a function of temperature alone.

            The results revealed that despite both groups having the same body temperature of 37°C, the live mice showed robust emissions, whereas the UPE from the euthanized mice was nearly extinguished.

            Blackbody radiation starts emitting around 500 C… this is something else I think. In the interest of science though, why don’t we experiment? Let’s heat Elon Musk to 500 C and see what color he glows?

              Blackbody radiation starts emitting around 500 C…

              blackbody radiation starts emitting visible light around 500 celsius. cooler objects emit at longer wavelengths.

                good point, thx. maybe we should run the experiment anyway just to be sure

      Is this actually a new finding? I’ve heard this as a fun fact probably ~15 years ago
