Time Travel Disproved By Pear-Shaped Nuclei
Time Travel may be put on hold indefinitely because of a new discovery made in the world of science – pear-shaped nuclei. These asymmetrical nuclei were first observed back in 2013 by the researchers at CERN in the Radium-224 isotope. It was also discovered to be the case with the Barium-144 isotope as well.
This discovery is of the utmost importance since our current understanding and the basis for our fundamental theories in physics are based on symmetry. The fact that nuclei were discovered to have more mass on one side than the other, puts our current understanding of the world on its head.
“This violates the theory of mirror symmetry and relates to the violation shown in the distribution of matter and antimatter in our Universe,” said Marcus Scheck from the University of the West of Scotland, and one of the authors of the study.
Up until this discovery was made, there were only three shapes of nuclei known to man – spherical, discus-shaped, and like a rugby ball. All of these shapes are symmetrical, which were all dictated by the combination of neutrons and protons found in an atom.
This new discovery, however, could help us understand why the universe is in the shape, size and composition that it is in.
“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,” sais astrophysicist Brian Koberlein
What about Time Travel?
Here’s where things get really interesting. Scientists have always been baffled about why time seems to move only in one direction. Well, even though they’re still not sure, these lopsided nuclei seem to point isotopes into a particular direction in spacetime, and this might be the reason behind why we time only goes forward and not backwards as well.
“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,” Marcus Scheck from the University of the West of Scotland told Kenneth MacDonald at BBC News.
Now, to be fair here, scientists aren’t sure about this themselves and they are merely speculating about this possible theory. But who to better understand physics and theorise about it than the physicists themselves, right? This theory does point to the idea that time travel is impossible, or at least, harder than previously believed, but as we’ve said, more research into the matter is needed.
