Gurzadyan & Penrose's response: the dispute is over what the null sky is
- what the source states
- "Two groups have confirmed the results of our paper concerning the actual existence of low variance circles in the cosmic microwave background (CMB) sky... We point out two discrepancies between their treatment and ours, however, one technical, the other having to do with the very understanding of what constitutes a Gaussian random signal. Both groups simulate maps using the CMB power spectrum for LCDM, while we simulate a pure Gaussian sky plus the WMAP's noise... we particularly emphasize that the low variance circles occur in concentric families, and this key fact cannot be explained as a purely random effect."
- what we infer
- The clearest primary-source statement that both sides agree on the data and disagree on the null ensemble — this record evidences what the disagreement is, not who is right. Note the position taken: ΛCDM-spectrum simulations are held to be the wrong standard of "chance" because, on the proponents' view, most of the CMB signal is not random.
- limitations
- A three-page unrefereed response note.
- The claim that concentric families 'cannot be explained as a purely random effect' is asserted, not quantified against the ΛCDM ensemble.
