Physicists Think They've Spotted the Ghosts of Black Holes from Another Universe
We're not living in the first universe. There were other universes,
full of black holes, in other eons before ours, a group of physicists has said. And we can detect traces of those long-dead black holes in space. https://www.space.com/41573-black-ho...universes.html -- Eduardo ---------- Alt119 - Alternate News www.alt119.net - Art Culture Lusophony [[Mod. note -- The technical paper behind this article is Daniel An, Krzysztof A. Meissner, & Roger Penrose "Apparent evidence for Hawking points in the CMB Sky" https://arxiv.org/abs/1808.01740 The authors claim that there are circular rings on the sky in which the CMB has relatively low variance, and that this is just what their "conformal cyclic cosmology" predicts. The space.com article notes that a previous similar proposal by Gurzadyan & Penrose (https://arxiv.org/abs/1011.3706) attracted strong criticism, with Wehus & Eriksen (https://arxiv.org/abs/1012.1268) and and Moss, Scott, & Zibin (https://arxiv.org/abs/1012.1305) arguing that that the frequency of occurence of the low-variance rings was no more than would be expected from random Gaussian noise with the known CMB angular power spectrum. -- jt]] |
