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 any laws 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.
