Newly Discovered Atomic Nuclei Explains Why Time Travel To The Past Is Impossible


The pear-shaped, asymmetrical nuclei, which was first observed by the CERN researchers in 2013, in the isotope Radium-224, has now been found in isotope Barium-144 as per a new study published in the journal Physical Review Letters.

This has the potential to shake molecular science as we know it, as most of the fundamental physics theories revolve around the symmetry of the nuclei. Now this pear shaped nuclei confirms that having more mass on one side than the other is possible.

One of the authors, Marcus Scheck of the University of the West of Scotland, said

“This violates the theory of mirror symmetry and relates to the violation shown in the distribution of matter and antimatter in our Universe,”.

This discovery will rattle the avenues of science, but in the end, will also help us understand the basis of our universe. Until now, we only knew the spherical, disc, and rugby ball shapes of the nuclei. And the specific combination of protons and neutrons shape up the distribution of charges within nuclei, which are symmetric and follow the theory of CP-symmetry.

As astrophysicist, Brian Koberlein commented,

“It’s been proposed that a violation of CP symmetry could have produced more matter than antimatter, but the currently known violations are not sufficient to produce the amount of matter we see. If there are other avenues of CP violation hidden within pear-shaped nuclei, they could explain this mystery after all.”

This distribution has also cleared up the conundrum of our forward direction in the spacetime continuum, and why we can’t travel backwards in time.

Marcus Scheck from the University of the West of Scotland said in an interview,

“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”.

While this theory is still speculative, the discovery has indeed opened new avenues of theoretical physics in the future.
