In a recent development, a team of researchers affiliated with the Raman Research Institute in India tried and replicated the results of an EDGES experiment. This experiment was conducted more than four years ago by a team of researchers from Arizona State University (ASU) and MIT in the US. Read more to find out what contradictions the Indian researchers have made.
Researchers at the Raman Research Institute in India used a device called the Shaped Antenna Measurement of the Background Radio Spectrum (SARAS) on the surface of a reservoir in India. After discovering the correct reservoir, the researchers set up the SARAS and began to search closely for evidence of the cosmic dawn.
But it turned out that there weren’t any. The RRI researchers claimed that this failure showed the team’s results in the US were flawed. They suggested that the earlier findings were likely due to faulty equipment. The Research for the same has been published under the journal Nature Astronomy.
In 2018, the #Nobel Prize-worthy detection of a signal from stars appearing in the early universe excited astronomers around the world.
However, Indian researchers have now disproved the claim of radio wave signals from cosmic dawn.

Background of the research that was contradicted
In 2018, a team of astronomers used an instrument called Experiment to Detect the Global Epoch of Reionization Signature (EDGES) to uncover evidence of the cosmic dawn. Comic Dawn is the light of the oldest stars in the universe. The research team had announced the discovery of a radio wave that announced the birth of the first stars. In addition, this cosmic signal is in a radio wavelength band used by many terrestrial communications equipment and TV and FM radio stations, which makes detecting the alien signal extremely difficult.
