Atom smasher a time machine!

In a 'long shot' theory, physicists propose that the world's largest atom smasher could be used as a time machine to send a special kind of matter backward in time.
The scientists outline a way to use the Large Hadron Collider (LHC), a 17-mile long (27-km) particle accelerator buried underground near Geneva, to send a hypothetical particle called the Higgs singlet to the past.
There are a lot of "ifs" to the conjecture, including the major question of whether or not the Higgs singlet even exists and could be created in the machine.
"Our theory is a long shot, but it doesn't violate anylaws of physics or experimental constraints," physicist Tom Weiler of Vanderbilt University said in a statement.
However, if the theory proves correct, the researchers say the method could be used to send messages to the past or the future.
Weiler and Vanderbilt graduate fellow Chui Man Ho describe their idea in a paper posted March 7 on the research website arXiv.org.
Elusive Higgs
The Higgs singlet is related to another theorized but not yet detected particle called the Higgs boson. This particle, and its related Higgs field, are thought to confer mass on all the other particles, and its discovery could help scientists answer the question, why do some particles have more mass than others?
The search for the Higgs boson was one of the main motivations for building the LHC in the first place. Since the atom smasher began regular operation last year, it has yet to find evidence of the Higgs boson, but the machine is still ramping up to its peak energies.
If the collider does succeed in producing a Higgs boson, some theories predict that it will create a Higgs singlet at the same time.
This particle may have a unique ability to jump out of the normal three dimensions of space and one dimension of time that we inhabit, and into a hidden dimension theorized to exist by some advanced physics models. By traveling through the hidden dimension, Higgs singlets could reenter our dimensions at a point forward or backward in time from when they exited.
