A successful large-scale simulation of the evolution of galaxies, with results consistent with what is actually seen by astronomers in the night sky, provides evidence that the theoretical underpinnings of the models employed, i.e., the supercomputer implementations ΛCDM, are sound bases for understanding galactic dynamics and the history of the universe, and opens avenues to further research.
Shadowdark is a dark fantasy tabletop role-playing game created by Kelsey Dionne and published in 2023 after raising 1.4 million dollars on kickstarter. As part of the Old School Renaissance, it focuses primarily on dungeon crawling.
William A. Barton reviewed Universe Gamemaster's Screen and System, World, and Environ Logs in The Space Gamer No. 48. [1] Barton commented that "if you don't have enough photocopies of the logs – or just want some connected in a book – and can't stand the thought of using anything but a Universe screen for Universe (and the [...] price tag doesn't deter you), you might find this accessory ...

An inhomogeneous cosmology is a physical cosmological theory (an astronomical model of the physical universe's origin and evolution) which, unlike the dominant cosmological concordance model, assumes that inhomogeneities in the distribution of matter across the universe affect local gravitational forces (i.e., at the galactic level) enough to skew our view of the Universe. [3]
The great majority of ordinary matter in the universe is unseen, since visible stars and gas inside galaxies and clusters account for less than 10% of the ordinary matter contribution to the mass–energy density of the universe. [12] The model includes a single originating event, the "Big Bang", which was not an explosion but the abrupt ...
In 1998/99, Merab Gogberashvili published on arXiv a number of articles where he showed that if the Universe is considered as a thin shell (a mathematical synonym for "brane") expanding in 5-dimensional space then there is a possibility to obtain one scale for particle theory corresponding to the 5-dimensional cosmological constant and Universe ...
