Gravitational waves were supposed to be produced from the merging of black holes and spotted in the fabric of the universe but, they did not.
Astronomers searched for gravitational waves for several years but, could not find any prove of their existence.

The 11-years of research is casting doubt on the world’s understanding of the formation of galaxies and black holes mergence. Albert Einstein's predictions about the existence of gravitational waves also remain unconfirmed. Gravitational waves are believed to come from the merging of two black holes but, no ripples in the fabric of the universe have been detected.
Using Parkes radio telescope in New South Wales, scientists tried to hear the “rumble” of the waves that were suppose to take place throughout the universe but, they were unable to detect any.
“We heard nothing. Not even a whimper,” said Dr. Ryan Shannon at CSIRO. “It seems to be all quit on the cosmic front – at least for the kind of waves we were looking for.”
“However, by pushing our telescopes to the limits required for this sort of cosmic search, we’re moving into new frontiers, forcing ourselves to understand how galaxies and black holes work.”
Galaxies have supermassive black holes in their center. When they combine with other galaxies, their black holes start orbiting each other. That is when Einstein’s theory of relativity, which he proposed a 100 years ago, should take place and ripples known as gravitational waves should be sent throughout the universe.
For the study, scientists studied the set of small stars or pulsar for eleven years and it is thought to be a good enough time to detect gravitational waves. Scientists suggest various reasons of why waves were not heard.
“There could be gas surrounding the black holes that creates friction and carries away their energy, letting them come to the clinch quite quickly.” Paul Lasky, a team member said.

The failure to detect gravitational waves is not the end; scientists will use other sophisticated telescopes and look into other sources such as coalescing neutron star to spot them.
