Cosmologists have used this Big Bang remnant to understand the history and very nature of our Universe, it would be truly bizarre if a pattern were to be discovered in this faint, apparently random microwave "noise." But this is exactly what Penrose and Gurzadyan were suggesting: they'd found a circular pattern in the CMBR. What's more, they proposed a theory as to what these ripples might be.
Could they be signals from universes past? Could they be the leakage of gravitational waves caused by the cataclysmic collisions of supermassive black holes before the Big Bang? Could this finding rock the foundations of Big Bang theory, inflation and the very origin of our Universe?
According to the authors of two new papers (2.1305">1,2) submitted to arXiv, the answer is: No.
Although the hypothesis presented by Penrose and Gurzadyan is certainly interesting, according to cosmologist Sean Carroll, they're just plain wrong.
The authors of these new papers are respected scientists who work with CMBR data on a daily basis. Although world renowned physicists, Penrose and Gurzadyan are not known for their work with CMBR data, and therefore may have misinterpreted what they are looking at.
