Oct. 28, 2020 New research proves theoretically that the Weak Equivalence Principle can be violated by quantum particles in gravitational waves - the ripples in spacetime caused by colossal events such as merging ...
Oct. 15, 2019 More accurate clocks and sensors may result from a recently proposed experiment, linking an Einstein-devised paradox to quantum mechanics. A physicist said the international collaboration aimed to ...
Oct. 2, 2019 According to quantum physics, energy can be 'borrowed' -- at least for some time. Energies lower than zero are possible, much like a bank account that can be overdrawn. There are, however, ...
Sep. 18, 2019 Researchers have announced a prototype for a laser at the heart of the first space-based gravitational wave observatory, known as the Laser Interferometer Space Antenna (LISA) ...
Sep. 16, 2019 Researchers experimentally determined a property of cadmium called the magic wavelength which is considered essential for the development of the most accurate clocks ever envisaged. The researchers ...
Sep. 11, 2019 Physicists have 'heard' the ringing of an infant black hole for the first time, and found that the pattern of this ringing does, in fact, predict the black hole's mass and spin -- more ...
Aug. 29, 2019 A physicist has proposed a new approach to solving one of the biggest theoretical problems in physics: the cosmological ...
Aug. 26, 2019 Researchers say they have discovered 'a new kind of quantum time order'. The discovery arose from an experiment the team designed to bring together elements of the two big -- but ...
Aug. 19, 2019 An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related ...
June 19, 2019 Using holography, researchers have found when gravity is combined with quantum mechanics, symmetry is not ...
May 17, 2019 One of the most unknown phenomena in modern physics is gravity. Its measurement and laws remain somewhat of an enigma. Researchers have revealed important information about a new aspect of the nature ...
Mar. 13, 2019 According to Einstein the speed of light is always the same. But according to theoretical models of quantum gravitation, this uniformity of space-time does not apply to particles. Physicists have now ...
Mar. 11, 2019 Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could spell the difference between life and death. ...
Mar. 8, 2019 Researchers have created a quantum circuit that enables them to listen to the weakest radio signal allowed by quantum mechanics. This new quantum circuit opens the door to possible future ...
Feb. 25, 2019 A NASA telescope that will give humans the largest, deepest, clearest picture of the universe since the Hubble Space Telescope could find as many as 1,400 new planets outside Earth's solar ...
Feb. 14, 2019 The option to measure the gravitational waves of two merging neutron stars has offered the chance to answer some of the fundamental questions about the structure of matter. At the extremely high ...
Feb. 4, 2019 In work that provides insights for several areas of wave physics -- Maxwell electromagnetism, topological quantum states, and plasmonics/metamaterials -- scientists showed that the well-known surface ...
Jan. 30, 2019 Researchers have demonstrated that whether an object (in our example, the ball) shows quantum features depends on the reference frame. The physical laws, however, are still independent of ...
Dec. 12, 2018 The gravitational waves created in the depths of space indeed reach Earth. Their effects, however, are so small that they could only be observed so far using kilometer-long measurement facilities. ...
Dec. 5, 2018 New research could shed light on the 'missing' dark matter and dark energy that make up 95 percent of our universe and yet are wholly invisible to ...
