In astronomy, dark matter is an invisible and hypothetical form of matter that does not interact with light or other electromagnetic radiation.Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be observed.
Dark radiation (also dark electromagnetism) [1] is a postulated type of radiation that mediates interactions of dark matter.. By analogy to the way photons mediate electromagnetic interactions between particles in the Standard Model (called baryonic matter in cosmology), dark radiation is proposed to mediate interactions between dark matter particles. [1]
Dark matter makes up 85% of all matter in the Universe, but astronomers have never seen it. The mass which we call dark matter does not give off light, heat, radio waves, or any other form of ...
To monetize the game, Epic Games had built an in-game storefront to offer cosmetics in the form of character skins, emotes, and other customization items for the player to use with their game avatar for Fortnite Battle Royale, using "V-Bucks" as the form of in-game currency to make these purchases.
With Fortnite’s future unclear, Epic Games pivots to emulate a rival game. The decision was worth billions. Part 2: Five years on, Fortnite’s future still was uncertain.
Among these models are many that modify the properties of dark energy or of dark matter over time, interactions between dark energy and dark matter, unified dark energy and matter, other forms of dark radiation like sterile neutrinos, modifications to the properties of gravity, or the modification of the effects of inflation, changes to the ...
The Lee-Weinberg bound [2] limits the mass of the favored dark matter candidate, WIMPs, that interact via the weak interaction to GeV. This bound arises as follows. This bound arises as follows. The lower the mass of WIMPs is, the lower the annihilation cross section, which is of the order ≈ m 2 / M 4 {\displaystyle \approx m^{2}/M^{4 ...
To mark the moment the European Union’s new Big Tech antitrust law comes into force, Tim Cook’s Apple has decided to test its limits with an extraordinary escalation of its long-running feud ...
