This paper presents strong observational evidence of numerous previously unobserved anomalous circular spots, of significantly raised temperature, in the CMB sky. The spots have angular radii between 0.03 and 0.04 radians (i.e. angular diameters between about 3 and 4 degrees). There is a clear cut-off at that size, indicating that each anomalous spot would have originated from a highly energetic point-like source, located at the end of inflation -- or else point-like at the conformally expanded Big Bang, if it is considered that there was no inflationary phase. The significant presence of these anomalous spots, was initially noticed in the Planck 70 GHz satellite data by comparison with 1000 standard simulations, and then confirmed by extending the comparison to 10000 simulations. Such anomalous points were then found at precisely the same locations in the WMAP data, their significance confirmed by comparison with 1000 WMAP simulations. Planck and WMAP have very different noise properties and it seems exceedingly unlikely that the observed presence of anomalous points in the same directions on both maps may come entirely from the noise. Subsequently, further confirmation was found in the Planck data by comparison with 1000 FFP8.1 MC simulations (with $l \leq 1500$). The existence of such anomalous regions, resulting from point-like sources at the conformally stretched-out big bang, is a predicted consequence of conformal cyclic cosmology (CCC), these sources being the Hawking points of the theory, resulting from the Hawking radiation from supermassive black holes in a cosmic aeon prior to our own.

Modak和Singleton [Phys. Rev. D 86，123515（2012）]提出了宇宙暴胀的类霍金辐射，它有一个自然的“打开”和一个自然的“关闭”机制。这种类似霍金的辐射导致了一种有效的负压“流体”，这导致了早期宇宙的快速膨胀。讨论了FRW模型在早期宇宙中不可能发生开启机制，因为它的视界是视视界而不是事件视界。因此，我们不能应用几何光学近似，这是隧道方法的必要条件。结果表明，该模型在视界出口处的宇宙微波背景（CMB）中预测了一个大于COBE归一化约束的$\fracρ{m_{pl}^4}$值。
