Montauk Project: Back in the day the US was testing a particular technology for time travel. Their goal was to send an entire battle ship to another time. Government officials are reported to have seen a green mist form around the hull and then a bright light (kind of like in pirates of the Caribbean) then it was gone. It reappeared later and most everyone was missing except for about 11 men who had been fused to the ship. There is one survivor who escaped the carnage unharmed. I am told he is under constant surveillance and anyone who searches for him are marked in a database and watched as well.
Haarp Mind Control: Of course, but there are other theories that state its purpose is for global weather control, causing earthquakes, and so on. The concept behind the mind control is to influence moods by sending out alpha, beta, and theda waves that we somehow pick up subconsciously and react accordingly. One really neat application for Haarp that is confirmed (i would have to find my source again, though) is that they can use it to image the earth to incredible depths.
Tesla: One thing that does warrant scrutiny about what happened with this man is that the government collected a whole bunch of his research and classified it under the reason of National Security. One of the neat stories about Tesla was near the time of his death he was in either Denver or New York apartment working on harmonics applications. His entire building began shaking violently, but no one could hear the source in his room so when the cops finally reached him in their efforts to evacuate the building the found out what he was doing. Needless to say they made his shut it off.
Dentists Spread Aids: The underlying reason why you don't really want to go to the dentist...
Laos Giants: This is something that locals say of a specific area. They claim that the giants are protecting gold and that is the reason they have been attacked by so many different countries. Many parties have entered the region in search of the treasure but are not heard back from.
Yes, I know the vast majority of CT's are ridiculous, but they are fun. I am not trying to espouse any beliefs, just trying to make a fun thread. All you folks that are bashing it are probably in on it together, private messaging each other of what to say, deciding who is good cop/bad cop, I am sure even the mods are watching closely.
