  • 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

  • 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?

  • '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. […]

  • First gravitational waves form after 10 million years
    on September 5, 2016 at 10:48 am

    If two galaxies collide, the merging of their central black holes triggers gravitational waves, which ripple throughout space. An international research team has now calculated that this occurs around 10 million years after the two galaxies merge -- much faster than previously assumed. […]

  • Quantum theory and Einstein's special relativity applied to plasma physics issues
    on July 29, 2016 at 11:01 pm

    Among the intriguing issues in plasma physics are those surrounding X-ray pulsars -- collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the sky. Physicists want to know the strength of the magnetic field and density of the plasma that surrounds these pulsars, which can be millions of times greater than the density of plasma in stars like the sun. Researchers have developed a theory of plasma waves that can infer these properties in greater detail than in standard approaches. […]
