Title: It's Gone Pear Shaped for Time Travel

Most of the fundamental theories of physics are based on symmetry. That symmetry dictates, among other things, that the nuclei of atoms can be one of just three shapes: spherical, discus or rugby ball.

But Dr Marcus Scheck at UWS and Professor Peter A Butler of the University of Liverpool have discovered a fourth form of nucleus.

It's pear-shaped.

[...]

In other words, a pear-shaped nucleus points to why our Universe contains so much more matter than antimatter.

But that's not all it points to.

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."

So time travel would appear to be a non-starter.

Cool discovery. I haven't read the white docs. If it pans out, then it would be the answer to a lot of open questions.

Excellent post. Fascinating as symmetry is fundamental to the current models.
