The phantom energy model of dark energy results in divergent expansion, which would imply that the effective force of dark energy continues growing until it dominates all other forces in the universe. Under this scenario, dark energy would ultimately tear apart all gravitationally bound structures, including galaxies and solar systems, and ...
Our results show that about 69% of our universe’s energy is dark energy. They also demonstrate, once again, that Einstein’s simplest form of dark energy – the cosmological constant ...
The universe's contents include ordinary matter - stars, planets, gas, dust and all the familiar stuff on Earth, including people and popcorn - as well as dark matter, which is invisible material ...
In cosmology, the cosmic coincidence is the observation that at the present epoch of the universe's evolution, the energy densities associated with dark matter and dark energy are of the same order of magnitude, leading to their comparable effects on the dynamics of the cosmos. [1]
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 ...
Although dark energy is currently the most popular explanation for the acceleration in the expansion of the universe, another theory elaborates on the possibility of our galaxy being part of a very large, not-so-underdense, cosmic void. According to this theory, such an environment could naively lead to the demand for dark energy to solve the ...
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 ...
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 .
