Scottish-based scientists have discovered that the nuclei of some atoms are not symmetrical.
The finding challenges some of the fundamental concepts of physics.
It could explain why there is more matter than antimatter - but it may also end hopes of time travel.
Dr Scheck says: “We’ve found these nuclei literally point towards a direction in space. This relates to a direction in time, proving there’s a well-defined direction in time and we will always travel from past to present.”
What does this mean? An absolute direction, and not one determined by local fields, or a direction fixed to the orientation of local fields?
I clearly need more information.
