WHILE scientists are still struggling to explain exactly what a black hole is, they are now examining the possibility of a counter to the mysterious entities – white holes. What scientists do know about black holes is that they are a point in space where the gravity is so intense that not even light can […]
You don’t have to look far to find outlandish theories on the nature of the cosmos and human consciousness. These days, notions once relegated to science fiction are finding their way into esoteric academic journals, and from there, into mainstream discourse. One example of this is the Simulation Argument, recently championed by Elon Musk; another is […]
Físicos han teorizado que, poco después de su aparición, hace 13.800 millones de años, el Universo estaba lleno de nudos formados por hilos flexibles de energía uniendo las partículas elementales. La idea proporciona una clara explicación de por qué habitamos un mundo tridimensional y se describe en un artículo aceptado para su publicación en el European […]
Imagine that the Universe we observe, from end-to-end, is just a drop in the cosmic ocean. That beyond what we can see, there’s more space, more stars, more galaxies, and more everything, for perhaps countless billions of light years farther than we’ll ever be able to access. And that as large as the unobservable Universe […]
A group of scientists confirmed that there is a pear-shaped nucleus. Not only does this violate some laws in physics, but also suggests that time travel is not possible.
A new form of atomic nuclei has been confirmed by scientists in a recent study published in the journal Physical Review Letters. The pear-shaped, asymmetrical nuclei, first observed in 2013 by researchers from CERN in the isotope Radium-224, is also present in the isotope Barium-144.
This is a monumental importance because most fundamental theories in physics are based on symmetry. This recent confirmation shows that it is possible to have a nuclei that has more mass on one side than the other. “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 of University of the West of Scotland, one of the authors of the study.
Until recently, there were three shapes of nuclei — spherical, discus, and rugby ball. There is a specific combination of protons and neutrons in a certain type of atom that dictates the shape formed by the distribution of charges within a nuclei. These three shapes are all symmetric and agree with the theory known as the CP-symmetry, the combination of charge and parity symmetry.
In the end, this could help us understand why our universe is the way that it is.As astrophysicist Brian Koberlein notes, “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.”
NO TIME TRAVEL?
This uneven distribution of mass and charge in the nuclei causes the isotope to ‘point’ in a certain direction in spacetime, and the team suggests that this could explain why time seems to to only go forward and not backward.
“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.
That said, it is a rather speculative hypothesis, but it does raise some rather interesting avenues for investigation.
In the end, this recent discovery is another indication that the Universe might not be what we thought, which could propel us to a new era of theoretical physics.
Blue Moon A blue moon is when the moon appears to be a shade of blue (the moon appearing with a tinge of blue) may occur in certain atmospheric conditions; e.g., when there are volcanic eruptions or when exceptionally large fires leave particles in the atmosphere. The term has traditionally referred to an “extra” moon, […]
The Universe through a Child’s Eyes There is something about parenthood that gives us a sense of history and a deeply rooted desire to send on into the next generation the great things we have discovered about life. And part of that is the desire to instill in our children the love of science, of […]
