Gravitational wave background discovered by NANOGrav as evidence of a cyclic universe — mentioned by sesm

Note that inflationary cosmology model this article is based on, is having a big crisis now, because it struggles to explain galaxy formation in early universe that is currently observed by JWST. However, cyclical cosmology model recently got a good theoretical basis in the works of Nick Gorkavyi. He found a mechanism for expansion-collapse cycles that is purely based on General Relativity without any quantum gravity theory. If you are interested, here are the papers: https://pos.sissa.it/335/039/ https://academic.oup.com/mnras/article/476/1/1384/4848298…

2, 3 and 4 are not Standard Model problems, but cosmological problems. There are cosmological theories that explain them by using only General Relativity without any changes to particle physics. For example, you can check out Nick Gorkavyi's cosmological papers: https://pos.sissa.it/335/039/ https://academic.oup.com/mnras/article/476/1/1384/4848298 https://academic.oup.com/mnras/article/461/3/2929/2608669 https://arxiv.org/abs/2110.10218 https://www.sao.ru/Doc-k8/Science/Public/Bulletin/Vol76/N3/A...
