Scientists believe they are one step closer to creating time travel.
American physicists from Vanderbilt University believe they may be able to use the Large Hadron Collider, the world's biggest atom smasher buried underground near Geneva, to send a type of matter called the Higgs singlet into the past.
But they're unsure if the Higgs singlet actually exists and whether the machine can produce it, according to a report by Live Science.

The Higgs singlet is related to another hypothesised particle called the Higgs boson, dubbed "God's particle" because it is associated with giving other particles mass, which the 27-kilometre long atom smasher may produce.
If the Higgs boson is created, the Higgs singlet may also appear, scientists say.
The Higgs singlet may be able to jump through space and time, travel through a hidden dimension, and then re-enter our dimension forwards or backwards in time, physicists Professor Thomas Weiler and graduate fellow Chui Man Ho believe.
"One of the attractive things about this approach to time travel is that it avoids all the big paradoxes," Professor Weiler said in a statement on research website arxiv.org.
"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."
The singlet, a highly technical term to describe the particle that doesn't interact with matter in the usual way, and boson are both named after theoretical physicist Peter Higgs.
The researcher's study is based on M... [continues]
