I remember reading up on a similar test where they put a type of electric sign that displays a few numbers suspended above in a similar fashion. The test was done by both informing and not informing that the counter was up their in the first place, & they reported failures every time either way.
On the subject of aliens. You may wanna take a look at this news article which just got released: http://news.sky.com/story/1143906/alien-bugs-discovered-in-earths-atmosphere
We are extremely lucky for the world, the plants, the water, our bodies. Everything (almost) works so flawlessly that one can think that it's all orchestrated. But I believe that the (natural) stuff that works is very very rare, I mean, the lowest chances of happening, and it happens. Except for the damn mosquitoes. Damn.
You know, there's no real reason for either to avoid being recorded. Psychology being what it is, everyone denies the pink elephant offering them flowers in the room, despite everyone seeing the pink elephant and taking the flowers. Sure, they might mention it between themselves in hushed tones, but around others? Obviously anyone sane would deny the elephant, and anyone who does not deny the elephant must not be sane. It obviously can't happen, so any evidence supporting its existance can't be true. Case and point: we're prejudiced against the possibility, so it's deemed impossible.
I've had a near death experience and it hasn't changed my viewpoint on the possibility of ghosts/spirits, which is that it's highly unlikely they exist. While I'm fascinated by stories with them in it, believing in such things without evidence isn't something I can do. The same goes for aliens, but at least we know that 1) Earth has life and 2) there are many other planets out there.
Aliens yes that i can believe and deal with. Ghosts in the sense that they are souls of the dead but not departed? not sure. although i will not discount anything. there is a lot about our existence and the universe that we do not yet or can not yet understand and explain. What if the ghosts are actually aliens...?
What if we are the aliens and the ghosts are the ancient inhabitants of the earth? or we are the ghosts and the aliens are the ancient inhabitants of the earth? or the ghosts are infact souls of dead aliens which came down to earth 100 millions of years ago?
seems the panspermia was a correct theory if this will be proven. as they say we're the sons of the stars
