Murmuring of the fabric of our Universe

Very recent, independent and  coordinated investigations by the established Pulsar Timing Array collaborations strongly indicate that the universe is humming with
gravitational radiation-a very low-frequency  rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. For these International Pulsar Timing Array-endorsed efforts, the European and Indian Pulsar Timing Array consortia, namely EPTA and InPTA, pooled together their resources that included combining EPTA's second data release and InPTA's first data release. The resulting detailed investigations reveal strong evidence for the presence of a stochastic gravitational wave background. I will share the excitement of our InPTA collaboration that employs niche abilities of TIFR's uGMRT. Possible directions that should be exciting to both astronomers and physicists will be listed.
