Galaxy Clusters Upend Einstein

Authors: George Rajna

It will be possible to use new astronomical mappings of hundreds of thousands of cosmic voids and galaxy clusters to test Einstein's theory of relativity by looking for small deviations in gravity at vast distances – a possible explanation for the dark energy that is accelerating the expansion of the universe. [30] By comparing different types of remote atomic clocks, physicists at the National Institute of Standards and Technology (NIST) have performed the most accurate test ever of a key principle underlying Albert Einstein's famous theory of general relativity, which describes how gravity relates to space and time. [29] "As crazy as all this looks, there appears to be strong reliability in these behaviors that could even be predictably and practically manipulated," Landman said. [28] A team of physicists from ICTP-Trieste and IQOQI-Innsbruck has come up with a surprisingly simple idea to investigate quantum entanglement of many particles. [27] For the first time, physicists have experimentally demonstrated ternary—rather than binary—quantum correlations between entangled objects. [26] The physicists, Sally Shrapnel, Fabio Costa, and Gerard Milburn, at The University of Queensland in Australia, have published a paper on the new quantum probability rule in the New Journal of Physics. [25] Researchers have studied how a 'drumstick' made of light could make a microscopic 'drum' vibrate and stand still at the same time. [24] A University of Oklahoma physicist, Alberto M. Marino, is developing quantum-enhanced sensors that could find their way into applications ranging from biomedical to chemical detection. [23] A team of researchers from Shanghai Jiao Tong University and the University of Science and Technology of China has developed a chip that allows for two-dimensional quantum walks of single photons on a physical device. [22] The physicists, Sally Shrapnel, Fabio Costa, and Gerard Milburn, at The University of Queensland in Australia, have published a paper on the new quantum probability rule in the New Journal of Physics.
