I had a similar thing happen with my pics while rehabbing an old historic iron workers house. The orbs started showing up in pics taken with 3 different cameras, as we started demoing the place. I have a really cool pic of one going up the stair case,half behind a post. Even more peaking out from behind the chimney in the basement. My camera as well as my pics were sent to the Kodak film school.(the job was for the state & they wanted to disprove any ghost theory,because there have already been claims made by people that had stayed there.The building was a rental cabin) They never offered a valid explanation.I was told to drop it! We even tried adding saw dust to the air to re create the shot, It didn't work. What we did manage to do was disprove any theories as to what they were. I'll see if I can find my pics,there on cd. I've read that there has been studies on such things,& they contain positive neutrons that can be read with a meter.There is a gent by the name of Girchberg that invented a lens that's going to revolutionize the way we see threw telescopes & microscopes. It uses a liquid crystal lens that allows us to determine the energy in the hydrogen bond. Basically we can view any thing with out killing it or causing damage to it. For example most viruses die as soon as they are removed from there host. They can now be viewed live. It's also gonna revolutionize space study...The theory behind orbs, are that they are balls of energy. When something dies does it's energy just die with it? Not according to science.....PS there's one on the bezel of the laptop too in your pic........Keep an open mind & you never know what you'll discover.
