Meet John Harrison. He is a Professor of Mathematics at Texas A&M University-Corpus Christi and Doctor of Theorical Physics. John came on to the show to talk about Thermodynamics and ghosts. If ghosts were to exist, how would they appear? Would it suck up a lot of energy? He also talks about the belief in orbs, and how they could be more plausible than actual full body apparitions. The most interesting question asked is how science can or can not explain away an after life. Also, John is asked about how spiritual photography, spirit boxes, and EVPS work in the actual science behind it. This is one episode you won't want to miss.
