      Yes – and I fight them all the time in the lab!!! 😉
      What we, laser scientists, call “ghosts” are unwanted laser reflections! You know when you look at a window, and you can see your face very faintly? That’s a little bit of light reflecting from the glass. Well, it happens to lasers too, but when it’s a bit of super powerful laser light, then the “ghosts” can be quite DANGEROUS!!
      I’m actually working on putting special patterns into glass to make it like the eye of a moth – so you could say, MOTHS HELP US FIGHT GHOSTS 😀

      No, I don’t think so. They would defy Thermal dynamics and so just cannot be real.

      I don’t believe in ghosts, And scientifically they cannot exist as they need an energy source. Life burns food for energy, ghosts don’t have anything to burn.
