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.
Holographic dark energy models, compared with cosmological constant models, imply a high degeneracy. [ clarification needed ] [ 18 ] It has been suggested that dark energy might originate from quantum fluctuations of spacetime , and is limited by the event horizon of the universe.

The fraction of the total energy density of our (flat or almost flat) universe that is dark energy, , is estimated to be 0.669 ± 0.038 based on the 2018 Dark Energy Survey results using Type Ia supernovae [7] or 0.6847 ± 0.0073 based on the 2018 release of Planck satellite data, or more than 68.3% (2018 estimate) of the mass–energy 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 attempts 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 ...
Since June 6, 2017, the Prime Minister and the Ministry of Public Security have deployed officials to Tay Ninh to decide to include the Dau Tieng water reservoir project in the list of important projects related to national security. [19] [20] By June 2019, the first solar power plant was established on the submerged area within the Dau Tieng ...
Phantom energy is a hypothetical form of dark energy satisfying the equation of state = with <. It possesses negative kinetic energy , and predicts expansion of the universe in excess of that predicted by a cosmological constant , which leads to a Big Rip .
