Re: In todays age
well actually those things that Nik00117 are quite small compared to what we (not as individuals but as in humankind) can do.
This is a question of belief, the US military/government (or any other countrys) does not admit that anything like this has ever happened, so it's just a matter of do u believe it or not, there certainly is some proof, but not enough to be 100% sure that these kind of stuff have happened.
we have travelled forward and backward in time
we have managed to teleport objects (with some MAJOR problems)
we have managed to make object invisible (to the human eye)
we have the ability to create stuff like earthquakes and hurricanes
and many other stuff of this nature
as I already said it's just about believing, and as Fox Mulder said " I wanna believe"
edit: oh and don't start the crap that this kind of technology is not possible, u don't believe in time travel read some of Einsteins stuff, he proved that it is possible. If it has ever been successfully done is another thing.
