What is Dark energy?


DARK ENERGY

Scientists have given the name dark energy because of the property of expansion generating unknown force or substance of the universe. Dark energy is just reverse of gravity. It pushes matter away rather than attracting them together. It is unknown whether the laws of physics or the general theory of relativity accounts for dark energy.


  In 1998 astronomers studying supernovae found them dimmer than anticipated. This meant both they were farther away as the universe is expanding faster than expectations . In theoretical it is almost impossible for travelling one galaxy to other. The nature of dark energy about scientists know is very little. 

If it is stable , it could continue to expand and accelerate forever. If it is unstable  the universe could ultimately will pulled apart like "Big rip". If it has the capacity to change , it could gradually de -accelerate and become an attractive force that contracts the universe like "Big crunch".

Bright light spots on Ceres surface | Alien Explorers

NASA's Dawn spacecraft found bright spots on Ceres Multiple bright spots in Occator crater stand out against the dark surface Credits: NASA/JPL-Caltech On February 19, 2015, NASA's Dawn spacecraft captured mysteriously bright spots on Ceres reflecting off the surface of the dwarf planet. While some scientists suggested that the lights are the result of something natural like ice fields or escaping gas, the higher resolution images failed to explain the bright lights.  After four months in June, the Dawn spacecraft captured even more incredible images; These images reveal what looks like a three-mile tale pyramid. Can these be possibly technological structures? The Question came in the mind are “Is this technological structure have been built by extra-terrestrials?
