Time Travel Possible?

Not really a new idea, but there it is.

Some of the smartest people are just plain retarded.

I found that very interesting.

So wait, what EXACTLY is holding you back from killing your father in the past? Just your conscience? Or is a physical bubble around you preventing you from committing thoughtcrime?

Or is your father physically going to be made of rubber.

I'm not buying this theory.

Yeah it's bull****.

Why don't they just accept it that IF it is possible to travel 'through time', you can only watch what happened earlier, not take part of it.

actually, what they're saying is that since in the present your father is alive, then you can't change that because the present has allready happened in the past many times. and no matter how many times you travel to point A in time it will always be the same because that's how it's always been. i actually understand what they're talking about, and it's not that something is stopping you from doing it, it's just it's imposible to re-write the past, so to speak. i wish i could explain it in more detail or in a more understandable manner, but without and diagrams i can't, and i'm just too lazy to draw anything in paint and post it.

I understand it as well, and explained it in my way.

that theory is a crock of ****.

heers a much more plausible theory:

there are infinite universes each with what "could" happen, now if you go back in time, your simply traveling to one of these universes, if not creating a new one all together, and this universe will carry out what has just happened, and will create a new future from there, at this point you might say well what proof is there that such different universes exist, b ut by the same token i'd say "your using logic to create a situation which you cannot facilitate in real life, so i'm just doing the same".

a theory like that is much more substantial than one that "when you come in with a knife he'll already have left the room", especially since even something like a footprint that wasn't there originally would substantially change the future. on top of that it said in the article that "obviously the future hasn't been changed" well what proof is there of that? the fact that we don't remember? of course we only remember what has happened as a result of the sum of changes taht havek happened to the timeline. The people of that article don't have an inkling of logic to their ideas.

I've come to my own conclusion that time travel is impossible, unless there is a way to control everything and EVERYONE in existence phsyically/mentally. (For example, once something has happened, the past has been left behind, and the physical entities that have lived out a scenario only exist in one time, and that is ours...).

Although there are infinite possibilities and scenarios that can occur, I believe there is only one 'physical version' of existence that exists which can actually 'live out' these scenarios, and unless you can cotnrol everything in our time to actually do the reverse of everything that has occured, time travel simply isn't possible. Even then it would be implausible, as you have to consider processes such as ageing, fuels that have been burnt, the expanding universe etc... To permit time travel, you would need to have control of existence and all of the above, and us mere mortal simply do not have that power.
