  • Low-altitude skiing can slow down aging -- relativistically
    on December 27, 2017 at 8:04 pm

    A doctor could tell you that skiing and running will most likely slow down aging. But how could mathematicians and physicists give their scientific support to this point of view? […]

  • Doing without dark energy
    on December 14, 2017 at 3:08 pm

    Three mathematicians have a different explanation for the accelerating expansion of the universe that does without theories of 'dark energy.' Einstein's original equations for General Relativity actually predict cosmic acceleration due to an 'instability,' they argue in a new paper. […]

  • Blackbody radiation from a warm object attracts polarizable objects
    on December 8, 2017 at 7:30 pm

    You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a research team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account. […]

  • Possible vestiges of a universe previous to the Big Bang
    on November 27, 2017 at 3:59 pm

    A researcher proposes to eliminate the need for cosmological space-time singularity and argues that the current expansion phase was preceded by contraction. […]

  • Dark matter and dark energy: Do they really exist?
    on November 22, 2017 at 4:30 pm

    Researchers have hypothesized that the universe contains a 'dark matter.' They have also posited the existence of a 'dark energy.' These two hypotheses account for the movement of stars in galaxies and for the accelerating expansion of the universe. But, according to a researcher, these concepts may be no longer valid: the phenomena can be demonstrated without them. This research exploits a new theoretical model based on the scale invariance of the empty space. […]

  • Breaking the rules: Heavy chemical elements alter theory of quantum mechanics
    on October 3, 2017 at 3:11 pm

    The theory of quantum mechanics does not adequately explain how the heaviest and rarest elements found at the end of the table function, say scientists. Instead, another well-known scientific theory -- Albert Einstein's famous Theory of Relativity -- helps govern the behavior of the last 21 elements of the Periodic Table. […]

  • Nobel Prize in Physics 2017: Gravitational waves

  • The principle Feynman and Einstein could not find was discovered
    on September 26, 2017 at 12:59 pm

    The Faraday’s induction formula (flux rule) of electromagnetism says that the electromotive force (emf) created in a conducting circuit is equal to the rate at which the magnetic flux through the conducting circuit changes as it is written on a high school text in physics. This emf can be calculated in two ways: either by using the Lorentz force formula and calculating the force acting on electrons in the moving conductor of the circuit; or via one of Maxwell’s equations (Faraday’s law) and calculating the change of the magnetic flux penetrating through the circuit. The Lorentz force formula and Maxwell’s equations are two distinct physical laws, yet the two methods yield the same results. […]

  • How Einstein's theory of gravitation experienced a Renaissance after World War II
    on July 12, 2017 at 3:05 pm

    Einstein's 1915 theory of gravitation (General Relativity), is now considered one of the pillars of modern physics. It contributes to our understanding of cosmology and of fundamental interactions between particles. But that was not always the case. In a new article, historians of science and physicists share their views on the process, especially the 'Renaissance' of General Relativity, following progressive transformation of the theory into a bona fide physics theory. […]

  • Mind the liquid gap: Liquids are capable of supporting waves with short wavelengths only
    on June 9, 2017 at 2:22 pm

    Flowing particles in liquids act as a filter to suppress long-wavelength waves but allow short-wavelength ones to be supported, according to physicists. […]

  • New confirmation of Einstein's General Theory of Relativity
    on June 7, 2017 at 4:38 pm

    Albert Einstein predicted that whenever light from a distant star passes by a closer object, gravity acts as a kind of magnifying lens, brightening and bending distant starlight. Yet, Einstein added, 'There is no hope of observing this phenomenon directly.' Now, researchers have done just that, saying that the discovery opens a new window to understanding 'the history and evolution of galaxies such as our own.' […]

  • Physicist builds on Einstein and Galileo's work
    on June 2, 2017 at 3:28 pm

    Sixteenth century scientist Galileo Galilei threw two spheres of different mass from the top of the Leaning Tower of Pisa to establish a scientific principle. Now nearly four centuries later, a team of physicists has applied the same principle to quantum objects. […]

  • New gravitational wave characteristics uncovered, researchers report

  • Using math to investigate possibility of time travel
    on April 27, 2017 at 1:17 pm

    After some serious number crunching, a researcher says that he has come up with a mathematical model for a viable time machine: a Traversable Acausal Retrograde Domain in Space-time (TARDIS). He describes it as a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path. The bubble moves through space-time at speeds greater than the speed of light at times, allowing it to move backward in time. […]

  • Physicists discover hidden aspects of electrodynamics
    on April 11, 2017 at 5:06 pm

    Radio waves, microwaves and even light itself are all made of electric and magnetic fields. The classical theory of electromagnetism was completed in the 1860s by James Clerk Maxwell. At the time, Maxwell's theory was revolutionary, and provided a unified framework to understand electricity, magnetism and optics. Now, new research advances knowledge of this theory. […]

  • Does the universe have a rest frame?
    on March 21, 2017 at 4:25 pm

    Physics is sometimes closer to philosophy when it comes to understanding the universe. Physicists are now attempting to elucidate whether the universe has a resting frame. […]

  • 'Blurred times' in a quantum world
    on March 9, 2017 at 5:05 pm

    When measuring time, we normally assume that clocks do not affect space and time, and that time can be measured with infinite accuracy at nearby points in space. Combining quantum mechanics and Einstein's theory of general relativity theoretical physicists have demonstrated a fundamental limitation for our ability to measure time. The more precise a given clock is, the more it 'blurs' the flow of time measured by neighboring clocks. […]

  • Historic detection of gravitational waves
    on February 19, 2017 at 9:51 pm

  • Increasing the sensitivity of next-generation gravitational wave detectors
    on February 10, 2017 at 6:10 pm

    Nearly one year ago today, the LIGO Collaboration announced the detection of gravitational waves, once again confirming Einstein's theory of General Relativity. This important discovery by the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO) has spurred great interest in improving these advanced optical detectors. The mission of gravitational wave scientists worldwide is to make gravitational wave detection a routine occurrence. Scientists from the institute that developed the lasers used in Advanced LIGO have made significant progress to support that goal. […]

  • Ancient signals from the early universe
    on February 10, 2017 at 6:09 pm

    For the first time, theoretical physicists have calculated the signal of specific gravitational wave sources that emerged fractions of a second after the Big Bang. The source of the signal is a long-lost cosmological phenomenon called 'oscillon.' […]

  • Substantial evidence of holographic universe
    on January 30, 2017 at 1:32 pm

    A UK, Canadian and Italian study has provided what researchers believe is the first observational evidence that our universe could be a vast and complex hologram. Theoretical physicists and astrophysicists, investigating irregularities in the cosmic microwave background (the 'afterglow' of the Big Bang), have found there is substantial evidence supporting a holographic explanation of the universe -- in fact, as much as there is for the traditional explanation of these irregularities using the theory of cosmic inflation. […]
