The 2017 Nobel Prize for physics has been ______(1)________ (given) to the LIGO-VIRGO collaboration for their detection of gravitational waves arising from the merger of two black holes. Gravitational waves are ripples in the fabric of space time _____(2)_____ (caused) by cataclysmic events in the universe such as colliding black holes or neutron stars. Though extremely violent, when these disturbances reach far-off regions in space and time the signals are weak and require extremely sensitive detectors to sense them. The very first detection of gravitational waves was _____(3)______ (make) in September 2015, a signal of a black hole merger 1.3 billion years ago. In other words, the signals took that long to travel to Earth. Hence the observatory offers a way of looking back in time to unravel mysteries pertaining to the early days of the universe’s existence. Since then, the LIGO-VIRGO collaboration has ______(4)_______ (identified) such signals four times. Just as astronomy offers a way of mapping the visible objects in the universe, gravitational wave astronomy is now a science of the near future whereby black holes, neutron stars and more such objects may be mapped. Rainer Weiss, who identified sources of noise that could drown the signal, gets one-half of the prize. Barry C. Barish’s main contribution in scaling up the project and Kip Thorne’s vision in guiding the large group of researchers are no less important, and in fact are aspects that capture the marvel of ______(5)______ (cooperation) in the LIGO-VIRGO collaboration.
