Dark Energy

What is dark energy Dark energy is an unknown energy which is said to occupy 70% of the universe. Energy is an unpleasant gravitational effect that accelerates the universe to the outside. No one knows exactly what the dark energy is, or where it comes from. Dark energy is a new idea. People do not know little about dark energy, but whether the universe occupies a large amount. Scientists say that by comparing spectral lines of elements by measuring the spectral lines of the same element measured in the laboratory and the red shift of the object, the universe is expanding at the accelerated rate Can be shown.

The nature of dark energy is currently inferred. Dark energy is a "vacuum energy" represented by "cosmic constant" (Λ, Greek capital letter lambda) in the general theory of relativity, a uniform uniform density of dark energy throughout space, and time or space Some people think that it is expansion. This concept was introduced by Einstein and is consistent with our limited observation to date. Alternatively, the dark energy may change over time in the universe. Only new observations can solve the problem

In physical cosmology and astronomy, dark energy is an unknown form of energy that is thought to tend to penetrate the universe and accelerate the expansion of the universe. Dark energy is the most accepted hypothesis for interpreting observations since the 1990s and shows that the universe is expanding at the accelerated speed. Assuming that the standard model of cosmology is correct, the best current measurements show that dark energy accounts for 68.3% of the total energy of today's observable universe. Mass energy of dark matter and ordinary (baryon) matter accounts for 26.8% and 9% respectively, contribution of other components such as neutrino and photon is very small. Dark energy density (about 7 × 10 - 30 g / cm 3) is very low, much lower than the density of ordinary and dark matter in the galaxy. However, because it is uniform throughout the universe, it dominates the mass energy of the universe.

Dark energy is the space between what we can think of visible substances. Regardless of whether it is bright or dark, all problems are basically energy. The dark energy is what we can call an adhesive that combines all the light of the universe. Dark matter has a lot of dark energy. This is the fundamental force behind the system, such as gravity, light, electromagnetic force. It is also a mechanism that some of us can call it the power of soul, the power of love or the power of light. Dark energy can be compared with damp sand on the beach - we have the ability to make sand from it then it can be left in its natural state. As we said, dark matter is the fundamental power of entropy and allows the sand castle to rot.
