Proof that there is no ghost

What if all the ghosts live in Japan? The Australian outback? Would it detect them then?

That's just what Julius Caesar and Nikola Tesla told them to say.

Except, if no one has ever detected ghosts before no one really knows for sure if we just haven't detected them or if they're not around to be detected.

My name is Zak Bagans. I've never believed in ghosts until I came face to face with one. So I set out on a quest to capture what I once saw onto video....With no big camera crews following us around, I am joined only by my fellow investigator Nick Groff and our equipment tech Aaron Goodwin. The three of us will travel to the some of most highly active paranormal locations, where we will spend an entire night, being locked down from dusk until dawn....Raw...Extreme...These are our Ghost Adventures.

You can't disprove anything

Ugh... Brian Cox. Easily the worst of the popular science figures.
