Well, I do not know if some of the people that post here are familar with the siencetific theorys that involve "time travel". The special theory of realitivity is one of the major ones. Time travel is possible only in the sence that as a object moves very very fast the time frame for that object kind of slows in respect to the time frame on earth. Now the ultamit speed any thing can travil is the speed of light and any thing with mass can not travil that fast. The closer a object comes to that speed the more the diferance in the time frames. So in theory if we could travil close to the speed of light we could take a trip and then return and we would have perceved that say 5 years had pased but on earth it would have seemed like 25-100 years. So very simply put that is the possibility of time trave. Time traves into the past is considered imposible by almost evey sientist but there are a very few who have come up with some realy far out ideas that would make it possible, but for the most part their are not taken very seiously. The theorys that govern realitivity get very tricky to understand and hard to understand but if anyone wants some more explanation look up the relativity on the net and there are some good sites, but they are not easy to understand, I have spent 8 years in the the sientific field and much of I still do not have a good feel for. (ie. everyone knows that the shortest distance from one point to antother is a strait line but time moves slower on a curved path) so anyway time travil like it is described in much of the post here is not posible and has no sientific basis. sorry guys.
 
If you can't conlusively prove that something is impossible, then it is by definition a possibilty, no matter how unlikely.

Can you conclusively prove that time travel is impossible?

PS..You say that the speed of light is the absolute speed limit of the universe. Can you conclusively prove that? What are your thoughts on quarks?
 
I think if you read some of the posts further down the line you will find several people here who have engaged in very reasonable and well thought out speculations on the possibility of time travel, pro and con.

It HAS been a little slow around here for a few days and a few of us who made some in depth disertations on the subject have heard the core issues each of us has addressed in our own detailed ways.

Frankly, I welcome some fresh blood to the debate my friend. Don't sell us too short too fast. There are some genuine thinkers here. Mostly from the present. :-)

Thanx.

Not to worry, Brain. In my experience, grasping
some of the more profound and complex concepts is
sometimes a sudden "Zen" type of epiphany.
Something that you come upon makes the other
pieces of the puzzle fit.
After first reading of Hugh Everett's "many worlds"
theories some years back, other sundry odds and ends
of quantum theory/mechanics fell into place for me.
Something along the lines of understanding the parts
so that it's easier to handle the "sum concept".
 
Re:Real theories

First Brian you may want to check your simple spelling before you post. Anyway, the only theory that says the absolute speed is the speed of light within a vacuum (it's been slowed to as little as 17 kph), is Relativity. So that as you approach the speed of light time around you relatively slows to the point when the speed of light is achieved and time relatively stops and you occupy all points in the universe simultaneously. That is a given.
Closed time-like curves, which you fleetingly refered to, would utilize this because they always are 4D objects, so that you could travel to any 4D point in the universe.
Other opinions on CTLCs are also very creditable, for example, check out "Can the universe create itself?" at
