Now this is a ghost I can believe in

F. GHOSTS OF A SIXTH KIND: A sixth type might be a form of time/space instant replay. We know from Einstein's work and other scientists that it may indeed be possible for events of the past to be in the present in a sort of time/space warp. This gets into some very complicated notions, but the idea is that some "ghosts" are not ghosts at all but are an instant replay of a past event.

In such cases what one sees is the ghost performing a certain scene repetitively. For example, a ghost of this type may go from the top of the stairs to the bottom and then disappear. This may happen over and over again. It never changes. The Ghost never interacts with anyone, and we cannot interact with it. It never changes facial expression nor does it ever acknowledge anything around it. Thus phenomenon is exactly like an instant reply on T.V. As some sort of time/space loop or instant replay, this Ghost is NOT a demon, or soul, or spirit. It is a phenomenon that given the right circumstances can probably be explained by physics. This type is NOT supernatural.

(Depending on the day, I might elect for G, too.)

This is how much science has brainwashed us.

Seven Types of Ghosts

If we were to get into a time machine with this computer and a power source and go back 1000 years, we would likely be accused of witchcraft. To the people 1000 years ago this computer machine would have been considered impossible. Its abilities would be considered the power of the devil. To them, this computer is supernatural. To us it is just another machine.

My first thought was, Not to mention the time machine itself! Which got me to reverse the idea altogether: How would we, technology-believers, react if the shoe were on the other foot?

If someone in strange clothes came up to you and said he just materialized from some year in the future, you'd think he was crazy and have him committed. But if someone said they came from the future and had a fancy contraption with him, you'd believe him! (Definitions of "fancy" may vary.)
