   6. Mai 2024 · Dark matter is stuff in space that has gravity, but it is invisible and isn’t like anything else we know about. Dark matter makes up about 27% of the universe. Dark energy makes up roughly 68% of the universe. We don’t know much about dark energy either, but we do know there is a lot of it. Together, dark matter and dark energy make up ...

   27. Juni 2011 · The origin of dark matter, matter-anti-matter asymmetry, and inflation. Anupam Mazumdar. A rapid phase of accelerated expansion in the early universe, known as inflation, dilutes all matter except the vacuum induced quantum fluctuations. These are responsible for seeding the initial perturbations in the baryonic matter, the non-baryonic dark ...

   10. Dez. 2020 · Francesco D'Eramo, Nejc Košnik, Federico Pobbe, Aleks Smolkovič, Olcyr Sumensari. We investigate scenarios with scalar leptoquarks that act as portals between the Standard Model and Dark Matter. We assume that Dark Matter is a scalar singlet which couples to a scalar leptoquark and the Higgs boson via the terms in the scalar potential.

   29. Juli 2021 · On the origin of matter in the Universe. Pasquale Di Bari. The understanding of the physical processes that lead to the origin of matter in the early Universe, creating both an excess of matter over anti-matter that survived until the present and a dark matter component, is one of the most fascinating challenges in modern science.

   20. Mai 2001 · We propose a new explanation for the origin of angular momentum in galaxies and their dark halos, in which the halos obtain their spin through the cumulative acquisition of angular momentum from satellite accretion. In our model, the build-up of angular momentum is a random walk process associated with the mass assembly history of the halo's major progenitor. We assume no correlation between ...
