Dark energy does not exist, some scientists have claimed – which could help get rid of one of the universe’s biggest mysteries. For a century, scientists have thought that the universe was ...
Under this scenario, dark energy would ultimately tear apart all gravitationally bound structures, including galaxies and solar systems, and eventually overcome the electrical and nuclear forces to tear apart atoms themselves, ending the universe in a "Big Rip". On the other hand, dark energy might dissipate with time or even become attractive.
The researchers used a year of observations by the Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory in Arizona, which can capture light from 5,000 galaxies simultaneously.
The Dark Energy Survey (DES) is an astronomical survey designed to constrain the properties of dark energy.It uses images taken in the near-ultraviolet, visible, and near-infrared to measure the expansion of the universe using Type Ia supernovae, baryon acoustic oscillations, the number of galaxy clusters, and weak gravitational lensing.

The chameleon is a hypothetical scalar particle that couples to matter more weakly than gravity, [1] postulated as a dark energy candidate. [2] Due to a non-linear self-interaction, it has a variable effective mass which is an increasing function of the ambient energy density—as a result, the range of the force mediated by the particle is predicted to be very small in regions of high density ...
Michael S. Turner (born July 29, 1949) [1] is an American theoretical cosmologist who coined the term dark energy in 1998. [2] He is the Rauner Distinguished Service Professor Emeritus of Physics at the University of Chicago, [3] having previously served as the Bruce V. & Diana M. Rauner Distinguished Service Professor, [4] and as the assistant director for Mathematical and Physical Sciences ...
In astronomy and cosmology, the dark fluid theory attempt to explain dark matter and dark energy in a single framework, as suggested by cosmologist Alexandre Arbey in 2005. [1] [2] The theory proposes that dark matter and dark energy are not separate physical phenomena, nor do they have separate origins, but that they are strongly linked together and can be considered as two facets of a single ...
AdventureQuest Worlds is a massively multiplayer online role-playing game set in the world of Lore, where players traverse its landscape and engage in quests and battles against various monsters, all while interacting with or alongside other players and non-playable characters (NPCs).
