Scientists at the University of California at Chicago have suggested that on the scale of the universe, gravity may not work as predicted by Einstein’s theory, which explains its accelerated expansion of the latter. According to the researchers, anomalous deviations can be detected through the registration of gravitational waves that occur when black holes and neutron stars merge. This is reported in an article published in the journal Physical Review D.
According to experts, gravitational waves, which are ripples of space-time, can collide with a supermassive black hole or a large cluster of galaxies on their way to Earth, which will change their characteristics compared to those predicted. This difference will be evidence in favor of the existence of unknown physical laws.
According to one of the proposed theory, in the Universe there is some additional particle that creates a “background” around massive objects. If a gravitational wave interacts with a particle, additional waves are generated, mixing with the main one. Scientists have identified what such an “echo” might look like, which will allow it to be identified in future observations using gravitational wave detectors.
