  • Measuring light and vacuum fluctuations from a time flow perspective

    07/10/2019 10:12:29 PM PDT · by ETL · 24 replies ^ | July 10, 2019 | Ingrid Fadelli,
    Some of the greatest unanswered questions about the nature of the universe are related to light, the vacuum (i.e. space where neither matter nor radiation exists), and their relationship with time. In the past, physicists and philosophers have addressed a variety of complex questions, for instance, what is the nature of the vacuum, and how is the propagation of light connected to the passing of time? Researchers at the University of Konstanz have recently carried out a study exploring the quantum states of light and vacuum fluctuations, as well as their interplay with time. Their paper, published in Nature Physics,...
  • New property of light discovered

    Beams with highly structured angular momentum are said to have orbital angular momentum (OAM), and are called vortex beams. They appear as a helix surrounding a common center, and when they strike a flat surface, they appear as doughnut-shaped. In this new effort, the researchers were working with OAM beams when they found the light behaving in a way that had never been seen before. The experiments involved firing two lasers at a cloud of argon gas—doing so forced the beams to overlap, and they joined and were emitted as a single beam from the other side of the argon...

    Scientists have launched a bid to observe and understand mysterious flashes of light on the surface of the moon. The ‘transient luminous lunar phenomena’ occur several times a week and illuminate parts of the moon’s landscape for a brief period of time before disappearing. Sometimes, a reverse effect which causes the lunar surface to darken has also been observed. Although there are several theories about the lunar mystery lights’ origins, they have not yet been fully explained. Now astronomers from Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany have set up a telescope which will use artificial intelligence to automatically detect the...
  • Chicago Skyline Visible 60 Miles Away in Michigan Due to Fata Morgana Phenomenon

    (The Chicago skyline was seen from 60 miles away across Lake Michigan in St. Joseph, Michigan, at sunset Saturday, May 4, 2019.) ------------------------------------------- Imagine gazing across Lake Michigan expecting to see the setting sun on the horizon, but instead seeing the skyline of a distant city. That's what happened in St. Joseph, Michigan, Saturday evening. This effect, captured on video by Joshua Nowicki, is called fata morgana, which is an optical bending of light by changes in air temperature over bodies of cold water, such as Lake Michigan in the spring. The skyline of Chicago can be seen from a...
  • Caltech Scientists Move Objects Using Only Light

    Researchers there have developed a way to levitate and propel objects using only light, by adding specific nanoscale patterning to their surface. Scientists have the ability to move and manipulate tiny objects with the use of ‘optical tweezers.’ The tweezers move objects via the radiative pressure from a sharply focused beam of laser light. However, this impressive tool can only move small very small objects a very limited distance. The trick is to create very specific patterns on the object's surface. These nanoscale patterns interact with the light so that the object keeps ‘righting’ itself if disturbed so that it...

    He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.( John 3:18-20)Unrepentant men hate the light of God; they shun it, run from it and seek to obscure it.

    Two Russian naval vessels have been fitted with a defensive weapon, which, during testing, caused some subjects to hallucinate and vomit because of its disorientating effect. RIA Novosti, Russia’s domestic state news agency, reported that a Russian military contractor had begun supplying the navy with the weapon, a “visual optical interference” device, named Filin 5P-42. The weapon’s name "Filin" translates to "Eagle Owl" in English. The technology, which was developed to dazzle and incapacitate attackers, has been deployed on the Russian naval frigates Admiral Gorshkov and Admiral Kasatonov, according to a news release from Ruselectornics, which created the Filin system,...

    I must work the works of him that sent me, while it is day: the night cometh, when no man can work. As long as I am in the world, I am the light of the world. ( John 9:4-5)Over and over again we are told in scripture that a night is coming to the world. It will be a time of the eclipse of truths that were introduced into this world by the Judeo/Christian revelation, which led to the greatest civilization ever seen. We in the modern world have taken so much for granted, which has come from the...

    But the path of the just is as the shining light, that shineth more and more unto the perfect day. The way of the wicked is as darkness: they know not at what they stumble. (Proverbs 4:18-19)The Bible tells us that everybody who ever lived is on a path. Life is not static, it is an ongoing journey. We are all headed in some direction, and we will be tomorrow, more of whatever we are today. Step by Step we progress, no one stays the same, and everyone ends up somewhere else at the end of the journey. The path...

    In the mean time, when there were gathered together an innumerable multitude of people, insomuch that they trode one upon another, he began to say unto his disciples first of all, Beware ye of the leaven of the Pharisees, which is hypocrisy. For there is nothing covered, that shall not be revealed; neither hid, that shall not be known. Therefore whatsoever ye have spoken in darkness shall be heard in the light; and that which ye have spoken in the ear in closets shall be proclaimed upon the housetops. (Luke 12:1-3)We have been discussing the biblical themes of ‘darknes’s and...

    If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us. (I John 1:8-10)We are looking at the Biblical teaching of the light of God. We see in scripture, “God is light and in him is no darkness at all” .

    One Russian company has announced a plan to build gigantic billboards in space, lighting up the night sky with advertisements for companies like Coke, McDonald’s, and KFC. If they’re successful, we could start seeing advertisements floating in the sky as soon as 2021. On the one hand, this is a pretty incredible technological marvel. The company, StartRocket, plans to launch dozens of tiny CubeSats into orbit roughly 280 miles above the ground in a single rocket. Those CubeSats would then fly in formation and deploy giant reflective sails to send the Sun’s light to the Earth. Each one of these...
  • Scientists design new material to harness power of light

    Scientists have long known that synthetic materials—called metamaterials—can manipulate electromagnetic waves such as visible light to make them behave in ways that cannot be found in nature. That has led to breakthroughs such as super-high resolution imaging. Now, UMass Lowell is part of a research team that is taking the technology of manipulating light in a new direction. The team—which includes collaborators from UMass Lowell, King's College London, Paris Diderot University and the University of Hartford -has created a new class of metamaterial that can be "tuned" to change the color of light. This technology could someday enable on-chip optical...

    Have you ever stopped to wonder exactly how much light has been produced by all the stars in the Universe, over all the time that has passed? Well, now you can wonder no more. An international team of astronomers has actually calculated the amount of starlight in the cosmos. And it's teaching us new things about the early years of our Universe. In the time since the Big Bang - roughly 13.7 billion years - our Universe has produced many, many galaxies, and many more stars. Perhaps around two trillion galaxies, containing around a trillion-trillion stars. For decades, scientists have...
