- Physicists have re-created a nuclear reaction that happened between 2 and 3 minutes after the Big Bang. Their measurement of the reaction rate nails down the most uncertain factor in a sequence of steps known as Big Bang nucleosynthesis that forged the universe’s first atomic nuclei. https://www.quantamagazine.org/physicists-pin-down-nuclear-reaction-from-moments-after-the-big-bang-20201111/ 17 comments space

- Physicists Argue That Black Holes From the Big Bang Could Be the Dark Matter. A flurry of recent papers has revived hope that the hidden dark matter in the universe could be clusters of “primordial” black holes conceived at the Big Bang. https://www.quantamagazine.org/black-holes-from-the-big-bang-could-be-the-dark-matter-20200923/ 12 comments science

- Scientists have identified a sub-atomic particle that could have formed the "dark matter" in the Universe during the Big Bang. Nuclear physicists at the University of York are putting forward a new candidate for the mysterious matter—a particle they recently discovered called the d-star hexaquark. https://iopscience.iop.org/article/10.1088/1361-6471/ab67e8 163 comments science
- Physicists have simulated in detail an intermediary phase,known as “reheating” period, that kickstarted the Big Bang in the universe’s first fractions of a second. http://news.mit.edu/2019/putting-bang-in-big-bang-1025 7 comments science
- Cosmologist claims Universe may not be expanding but the mass of everything has been increasing. Such an interpretation could help physicists to understand problematic issues such as the so-called singularity present at the Big Bang. https://www.nature.com/news/cosmologist-claims-universe-may-not-be-expanding-1.13379 321 comments space
- Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang. Physicists, who have devised a new cosmological model positing the existence of an “antiuniverse” which, paired to our own, preserves a fundamental rule of physics called CPT symmetry. https://www.reddit.com/r/space/comments/acv1xw/our_universe_could_be_the_mirror_image_of_an/ 3 comments space
