Apparently their idea also has external consistency with measurements.

Gurzadyan and Penrose are saying that there is observational evidence for a particular cosmological model known as Conformal Cyclic Cosmology (CCC). Specifically, the evidence comes from measurements gathered by the Wilkinson Microwave Anisotropy Probe (WMAP) (a satellite) and Boomerang '98 (a balloon flight above Antarctica in 1998, which also measured temperature fluctuations in the cosmic microwave background).

Specifically, they claim to see the signatures of supermassive black hole encounters in the aeon prior to the Big Bang - these show up as families of concentric circles over which the temperature variance is anomalously low in the cosmic microwave background radiation.

Of course, other cosmological models might also be consistent with the measurements they cite.

The only consistency that exists with measurements is that theories are formulated as a potential interpretation of them.

So, back to my original hypothesis..

Note the second author.

Care to expand on that?

Basically, these observations only have significance if you assume that inflationary cosmology is correct.

Actually, these observations don't seem to fit with standard inflationary cosmology.

"...to reproduce the effects that we appear to see, within the framework of inflation, one would require a mechanism for producing recurrent explosive events close to the inflationary turn-off point. No such mechanism has ever been seriously contemplated."

(but someone might start seriously contemplating it now!)
