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).
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 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
