This is called the split-perception theory if you're looking at your phone or distracted by something else, and only glance around quickly, your perception might be split into two parts rather than one, and makes your hippocampus slightly confused. You're Not Paying AttentionĪpparently, the more distracted you are, the more likely you are to experience déjà vu. If you're wondering what your brain is trying to tell you, though, this is what déjà vu might communicate. "This occurrence gives us the sense that we have seen or experienced something before." This misfiring is often nothing to worry about a 2003 study published in The Journal of nervous and mental disease found that over 70% of people experience it. "One section of the hippocampus, a small curved part of the brain, activates two different neural circuits which concurrently absorb your present experience while the second circuit assesses memories," she says. Scientific American reported in 2014 that small seizures in the brain responsible for memory formation and retrieval could be the reason something suddenly feels familiar, despite your having never experienced it before.Ĭognitive scientists actually know exactly what happens in your brain when you experience déjà vu, neuropsychologist Sanam Hafeez, Psy.D. While déjà vu, which is French for "already seen," can make you feel like you've known someone or been somewhere before, it's likely all in your head, according to science. However, there are things your brain is trying to tell you when you experience déjà vu.

(2015) Model for Thermal Relic Dark Matter of Strongly Interacting Massive Particles. The article can be found at: Hochberg et al. The next step will be to put this theory to the test using experiments such as the Large Hadron Collider and the new SuperKEK-B, and a proposed experiment SHiP. Yonit Hochberg adds, “The key differences in these properties between this new class of dark matter theories and previous ideas have profound implications on how dark matter can be discovered in upcoming experimental searches.” University of California, Berkeley postdoctoral researcher Dr.
Eric Kuflik, a postdoctoral researcher at Cornell University. “It can resolve outstanding discrepancies between data and computer simulations,” says Dr.
The new theory predicts dark matter is likely to interact with itself within galaxies or clusters of galaxies, possibly modifying the predicted mass distributions. Hitoshi Murayama, professor of physics at the University of California, Berkeley, and Director of the Kavli Institute for the Physics and Mathematics of the Universe at the University of Tokyo. It is incredibly exciting that we may finally understand why we came to exist,” says Dr. It has the same properties-same type of mass, the same type of interactions, in the same type of theory of strong interactions that gave forth the ordinary pions.
“We have seen this kind of particle before. Now an international group of researchers has proposed a theory that dark matter is very similar to pions, which are responsible for binding atomic nuclei together. Yet no one has been able to observe it, and it has often been regarded as a totally new exotic form of matter, such as a particle moving in extra dimensions of space or its quantum version, super-symmetry. We owe a lot to dark matter-it is the thing keeping galaxies, stars, our solar system, and our bodies intact. 3, 2015) – A new theory published in Physical Review Letters says dark matter acts remarkably similar to subatomic particles known to science since the 1930s.
