Dark matter's gravitational effects are essential for galaxy formation. 5 Dark Energy Integral to the universe's fate. The role of dark energy in the universe's future expansion is a major cosmological question. 6 Common Curiosities What percentage of the universe is dark matter? Dark matter ma...
To understand why it is estimated that the dark matter accounts for 23% and the dark energy accounts for about 73% of universe constituents.SOLUTION: The orbital energy inside the universe is made by a black hole at the center of the universe. The orbital energy outside the universe is ...

The form of both the dark energy and dark matter that results from the above class of models is insensitive to the specific form of the scalar field Lagrangian. By adding an appropriate perturbation, which breaks the above hidden symmetry and along with this couples dark matter and dark energy...
Professor Maeder argues that by doing away with the ideas of dark matter and dark energy, or at least the need for them to exist, the concept could contribute to "potentially solving two of astronomy's greatest mysteries." He goes back to basics to posit a "starting hypothesis that has no...
NASA's Dark Energy Hunt Combines Powerful New Tools and 2 Missions What is dark matter? A number of experiments have sought to unravel the mysteries of the hard-to-find energy. Some suggested that dark energy is woven into the very fabric of the universe, while others thought it could ...
fill in the gaps has produced some fairly mind-boggling figures. By modern estimates, the universe is only about 5% regular matter and energy and about 27% dark matter, or more than five times as much. The remaining 68% of the universe is thought to be darkenergy—a topic for another ...

We investigate some properties of exotic spherical configurations made of dark matter and dark energy. For the former, we adopt a polytropic equation-of-state, while for the latter, we adopt the extended Chaplygin gas equation-of-state. Solving the Tolma
