Finding dark matter in the universe is like finding a needle in a haystack of cosmic proportions. The tool of choice is the Dark Energy Camera, with 570-mega pixels and installed in the 4-meter Victor M. Blanco telescope that is located in the Andes Mountains in Chile. This is scalpel equipped with five lenses, one is about a yard in circumference to provide a sharper focus for better imaging.
Looking for traces of dark energy which is predicted to exist, but not visible. Confirmation is needed to verify if the galaxies are speeding away in expansion, or slowing down. How much dark energy is really out there and whatever its real nature is.
Answering the fundamental questions of how the universe is here, and what is dark matter once and for all. All the answers should be provided by the dark energy survey (DES) in five years, then scientists will have models to build on. So, the standard model does not provide the answers needed to clear up the mystery. Questions, whether it can be found, are now taken into consideration, but trying to find and seek proof seeks precedence over anything else.
Once the mission does begin, it will be imaging 100,000 galaxies and up to 8-billion light years away when it captures an image. Identifying the areas with dark energy is not done by visualizing it, it cannot be done yet. Instead, the universal expansion is measured to pinpoint what dark energy is the universe.
DES will utilize several ways to examine dark energy
How many galactic clusters are out there, that is pulled together by gravitation or whether dark energy is causing the expansion. Imaging light from 100,000 galaxy clusters over billions of light-years far from us. How many points in time will show how much gravity and dark energy plays a tug-o-war in the firmament of reality.
Tracking all the supernova explosion that is detectible, and lights up the galaxy with a release of gamma-rays like a lighthouse in eternity. Determining the intensity of light will give the answer to how fast the cosmos is getting apart. About 4000 supernovae will be found, and these stars will be dead for billions of years, because of the red-shift from immense light years into the past.
One of the indicators of dark matter in spacetime is the non-linear path or bending of light when it encounters it. It causes a noticeable distortion of images in the images from the telescope. Shapes of 200 million galaxies will reveal the effects of gravity and dark matter like cosmic road bumps in the universe.
Sound waves are used to make a model of galactic expansion as it progresses over time. At 400,000 years old, when the universe had an interaction of matter and light, sound waves were nearly traveling the speed of light. This is like a universal symphony, that left recordings in the remnants of the old universe. The Dark Energy Survey (DES) will find traces of the archaic sound in galaxies, and guess how it is in the existing universe.
