Let Us Learn About Dark Energy
The theory of gravity planned by Albert Einstein nearly a century ago can explain the dance of galaxies about one another just as well as it can model the motion of planets around the sun, according to a fresh study.
The finding suggest that the unseen substance called dark matter and the even more unexplained force known as dark energy are not just figments of physicists' imaginations .Provides information on a plan to produce electricity on a small or larger scale using gravitational energy.
Dark energy and the accelerating universe
Dark energy could be exotic new particles or other undiscovered physics. Dark energy could mean that our understanding of gravity needs an overhaul. Or it could be something completely different — perhaps something that no one has even thought about. It could require scientists to revise their ideas about the Big Bang, or even develop an entirely new scenario to explain how the universe was born.
Dark energy is not only terribly important for astronomy, it's the central problem for physics. It's been the bone in our throat for a long time. Dark energy is necessary to account for the fact that the Universe is apparently not just expanding, but accelerating at an ever-faster pace. In the current standard model of cosmology, dark energy currently accounts for almost three-quarters of the total mass-energy of the universe.
In our next blog we shall learn about dark matter.
