We Emit a Visible Light That Vanishes When We Die

I came across this article today and wanted to share it. In the image above, you'll see the contrast between light emitted in the body when alive, versus dead.
Although to skeptics the idea of biological electromagnetic emissions (e.g., auras) may initially seem “fringe”, researchers from the University of Calgary, led by physicist Vahid Salari, reported detecting ultraweak photon emissions (UPE) from living animals and some plant leaves. These emissions, typically too faint to detect due to environmental interference, were observed in clear contrast to non-living bodies, suggesting a potentially significant biological phenomenon.
Researchers placed mice in a dark environment and measured ultraweak photon emissions (UPE) before and after death. By maintaining body temperature post-mortem to control for heat, they found a clear drop in visible light photon emissions after euthanasia, indicating a measurable difference. Essentially, our life light disappears after we die...
Reading this paper, my first thought was: well then, what happens to that energy once it leaves the body? Where does this living light go? If energy cannot be destroyed then it’s fascinating, and reassuring, to consider the possibility that it doesn’t simply disappear. If that energy persists, perhaps this is a small piece of evidence pointing toward the idea that something of us lives on. I’ve always believed in the enduring nature of the soul, and it’s comforting to see science beginning to explore phenomena that resonate with what many of us know and feel intuitively.
