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.
The 5th edition Dungeon Master's Screen from the core rule book gift set collector's edition by the artist Hydro74. A Dungeon Master's Screen was released for the game's 5th edition in January 2015. A revised version, titled Dungeon Master's Screen Reincarnated featuring revised artwork and charts was released in September 2017. Additionally ...
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.
Mixed dark matter (MDM) is a dark matter (DM) model proposed during the late 1990s. [1]Mixed dark matter is also called hot + cold dark matter. The most abundant form of dark matter is cold dark matter, almost one fourth of the energy contents of the Universe.
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.

His primary contribution is to cosmology as one of the first physicists to suggest that most of the mass and energy of the universe resides in empty space, an idea now widely known as "dark energy". Furthermore, Krauss has formulated a model in which the universe could have potentially come from "nothing," as outlined in his later book A ...
For the Lambda-CDM model with a positive cosmological constant (as observed), the universe is predicted to expand forever regardless of whether the total density is slightly above or below the critical density; though other outcomes are possible in extended models where the dark energy is not constant but actually time-dependent.

LCDM – (astrophysics terminology) Lambda cold dark matter, any model for structure formation in the universe that includes dark energy. also ΛCDM; LCO — (observatory) Las Campanas Observatory, Atacama Region in Chile; LCOGT – network of autonomous robotic telescopes (2m, 1m and 40 cm) at 7 sites in both hemispheres
