General relativity is classical in nature while quantum mechanics upholds the idea of quantization and interference at the subatomic scale. Quantum (field) theory successfully accommodates all the interactions of nature in its framework but gravity (this framework is called the Standard Model of Particle Physics). However, general relativity is the only available tool to study all the manifestations of the gravitational field.
Vivek Venkatraman Krishnan and his team at the Max Planck Institute for Radio Astronomy in Bonn, Germany, detected relativistic frame dragging while studying a celestial laboratory located thousands of light-years away. The results were published in Science on January 30. Discovered in 1999, the laboratory, in the direction of the Southern Cross constellation, consists of […]
