Don't be fooled by the similar names, dark energy and dark matter — sometimes grouped together and described as the "dark universe"' — aren't believed to be related aside from a few superficial similarities. Dark energy vs dark matter: What's the difference? Diagram showing the...
light scalar field condensating under the form of a galaxy-sized Bose–Einstein condensate [21–26], dark fluid which hypothesizes that dark matter and dark energy are the same entity [27–30], self-interacting dark matter which has a self-interaction and is not collisionless [31,32], ...
What is the nature of dark matter and dark energy, which together make up about 95% of the Universe’s energy content? One way to address such a question is to investigate the evolution of cosmic structures on the largest observable length scales (Fig. 1). Fig. 1 Simulation result showing...

Dark Energy : Dark Matter : Dark Gravity Watch on Advertisement - Continue Reading Below But there's another possibility. Some theories suggest dark matter might interact with itself via some yet unknown "dark force." A fifth fundamental force we've never documented before. It's what we're ...
I’ll be uploadingbrand-new scenes every week, so my patrons will have an exclusive, front-row seat to the unfolding chaos, drama, and seduction that’s coming in“Unholy Intentions”. If you love the ruthless alpha energy of my previous books, you’ll want to get in on this!

whereais the cosmic scale factor. We assume that the universe is filled with pressureless dark matter (DM) and HDE. We exclude baryonic matter and radiation due to their negligible contribution to the total energy budget during late time evolution. In the above formalism, the Brans–Dicke field...
“From their birth, fae emit a certain kind of energy. An aura, if you want. Like the name suggests, Ares Amberson was first and foremost a warrior prince, because he was born with martial magic. He would one day become head of the Scorpio Army. But the dark magic King Gariel cast ...
