Weiler and Ho suggest that if the LHC can reproduce a Higgs boson, it will also be able to produce a related particle, called the Higgs singlet, at the same time. This is the crucial ingredient as they theorize that these singlets would serve as jumping off points with the ability to move into other dimensions, moving across time.

"One of the attractive things about this approach to time travel is that it avoids all the big paradoxes," Weiler said. "Because time travel is limited to these special particles, it is not possible for a man to travel back in time and murder one of his parents before he himself is born, for example. However, if scientists could control the production of Higgs singlets, they might be able to send messages to the past or future."

Time-Travel may be theoretically possible, although (and I may be reading this wrong) it seems that they are really talking about dimensions rather than time.

So if this theory turns out to be 'doable' sending messages back and forth through time?

Wouldn't that be a little dangerous?

Any of the Physics gurus know how this would affect Entropy?

See that is what I do not get, the article states that the paradoxes involved in time travel are not applicable, yet your example would suggest otherwise.

I was just about to say that I don't see how this removes the paradoxes associated with time travel.

Mind ready to explode!

Exactly the reason why Time Travel isn't possible... in my opinion :p

If this was possible we'd probably know about it already: Somebody in the future would have done it, and then sent a message back to our time.

Except that if they did send the message back using these particles then we would have been oblivious as we haven't even produced or discovered them in the LHC yet ;)
 
how do we know for sure that no one has sent a message back? Maybe certain advances in science and technology didn't come about by accident. dun dun dun
 
So, say we sent a message back telling people to assassinate Hitler before WW2 sparked off, wouldn't that change everything meaning that a new dimension is created, where WW2 did not occur or occurred but due to different circumstances?

If messages kept being sent would more and more dimensions be created, where events go on a different path to our own or would it affect our dimension?

My head hurts now.
 
I have read one theory that says if you could go back in time, it wouldn't be your time line you ended up in, due to the many worlds theory.

So you could go back and murder your grandad, but since it is a different dimension/timeline/world, it is not technically your grandad so you wouldn't cease to exist, but the other you would vanish.

Or something. :p

We're entering Fringe territory now.
