Physicists Currently Discovered a Completely New form of Light

Physicists have presently discovered a new form of light that doesn't follow our existing rules of lanky momentum, and it could shake up our understanding of the electromagnetic emission and lead to faster, additional secure optical communication.
Because of how well-studied and, well, all over, light is, you might assume that we've pretty much learnt all there is to know about it. But presently last year, researchers identified a fundamental new property of light, and now a side of Irish scientists has shown that light can take on unexpected new forms.
One of the ways we measure a beam of light is from side to side its angular momentum - a constant quantity that measures how a great deal light is rotating. And until now, it was thought that for all forms of light, the angular momentum would be a whole number (known as an integer) multiple of Planck's constant - a physical constant that sets the scale of quantum belongings.
But researchers led by Trinity College Dublin have now demonstrated that a latest form of light exists, where the rangy momentum is only half of this value.
"What I think is so thrilling about this result is that even this fundamental property of light, that physicists have forever thought was fixed, can be changed," said lead researcher Paul Eastham.
Let's back up for a second here and give details what all that means.
As one of the researchers, Kyle Ballantine, explains:
    "A beam of light is characterised by its colour or wavelength and a less recognizable quantity known as angular momentum. Angular momentum events how much something is rotating. For a beam of light, although travelling in a as the crow flies line, it can also be rotating around its own axis. So when light from the mirror hits your eye in the dawn, every photon twists your eye a little, one way or another."
As mind-bending as that might sound, it's all well understood by physicists. But what they didn't realise was that light could live that had an angular momentum that wasn't a whole digit.
To figure this out, the team approved light through crystals to make beams of light that had a twisted, screw-like structure. They were look for new light behaviours that might improve optical infrastructure, but when they analysed this particular beam within the theory of quantum mechanics, it looked as though its angular instant would be a half-number - which definitely wasn't what they'd expected to discover.
The biggest impact, other than shaking up our sympathetic of light, is that this new information could help to improve speed and security along fibre-optic cables, most important to faster, safer internet connections.
But before we get anywhere lock to benefitting from this new form of light, one more team of researchers will need to replicate and validate this work to build sure it wasn't just a one-off. Science is often a slow procedure, but there's no denying it’s a thrilling-one.

  1. I can see molecules flying around my eyes

  2. On this topic: "Illusions of Human Thinking: On Concepts of Mind, Reality, and Universe in Psychology, Neuroscience, and Physics" (2016), Author: Vacariu, Gabriel, (Springer, Germany). On Springer site:

    • The Book delivers a new axiomatic-hyperontological framework for a non-contradictory conceptual understanding of "Welt" ("Universe")
    • Shows how to solve fundamental and philosophical problems of Science ("Pseudoproblems")
    • Gives deep insight into philosophical discussions of Philosophy of Mind, Neurosciences, Psychology, Theory of Relativity, Quantum Mechanics

    “The book illustrates that the traditional philosophical concept of the "Universe”, the "World” has led to anomalies and paradoxes in the realm of knowledge. The author replaces this notion by the EDWs perspective, i.e. a new axiomatic hyperontological framework of Epistemologically Different Worlds” (EDWs). Thus it becomes possible to find a more appropriate approach to different branches of science, such as cognitive neuroscience, physics, biology and the philosophy of mind. The consequences are a better understanding of the mind-body problem, quantum physics non-locality or entanglement, the measurement problem, Einstein’s theory of relativity and the binding problem in cognitive neuroscience.”

    [At my webpage (Philosophy, University of Bucharest), see my article 2005 Synthese (USA) + five books free (2008, 2010, 2011, 2012, 2014 each posted on Internet when it was published) on Cognitive (Neuro)science, Physics (quantum theory and Einstein’s relativity), Philosophy (of mind). On Amazon, two books: “Dark matter and dark energy, space and time, and other pseudo-notions in cosmology” (2016) + “Is cognitive neuroscience a pseudoscience” (2015)]

  3. Their research could lead to a scientific leap or bound :) so where does it fall on the light spectrum ?
