This thread is a great example of how easy it is t believe something you've never really thought about.

Time travel is absolutely IMPOSSIBLE

No one can go back in time and change things, heck, the fact alone that you're going back in time will make things different. Which you can't so it's impossible.

Imagine a time traveler goes back from now to 1 sept. 2001 and somehow manage to prevent the sept. 11 events, exposing many shocking facts etc. How much difference will that make for us right here right now in 2008?

Or let's take another view on this.

What sense does it make if one could go back in time and change things? What do you think you can do if you were able to go back in time? "Time" and thus existance wouldn't make any sense at all.

Or another view.

Imagine you pick a 2 hour movie you watch it for 1,5 hour and see one character do something you don't like. Now you rewind the movie and you edit it in a way that the character you didn't like @ 1,5 hour in the movie to get killed let's say @ 30 mins in the movie.

Now how much sense will that make for the rest of the movie?
The movie will completely change and everything will have to be different. It will NEVER be the same movie you saw up to 1,5 hour. Impossible!

It's not difficult to understand this peoples.
I believe that it may be possible to "look" into history, or other dimensions, but you can NEVER be there and interact!

For example NO ONE can go back in time and assist at his/her own birth! Not gonna happen folks.

I think the problem with believing this has mainly to do with peoples who feel sorry for things they've done wrong in the past. Many have this strong desire to do things different, to wish they've made different choices in the past etc. I think we could better put all the time, money and energy in finding ways how to extend our lifes instead on time travel which is just bullshit.

Some say the philadelphia experiment was real, but if you examine the known information it strongly suggest dimensional travel. I do believe in multiple dimensions, I do believe the universe it self is a loop, a closed system with no start of end, it's like circle. In fact everything, even straight lines can be tracked down to "circles".

I hope this is understandable, I'm not English nor American.

Oh and one more thing I'd like to add. In the universe there are certain laws that makes things work the way they do. For example a ship needs to be build a certain way for it to float.

You can not change the way some things works and time is one of them. Time is an interpretation of the flow of energy. A picture is nothing but a static image without any flow. Since everything is done by energy passing from atom to atom
