Map of the Most Accurate Dark Material of All Time Released

Map of the Most Accurate Dark Material of All Time Released


The International Dark Energy Consortium (DES) has just released the most accurate map of dark matter in the universe.

The map, according to Professor Ofer Lahav from University College London (UCL) and chair of the DES Advisory Board, will provide new information on how the universe operates.

The reason, even though scientists already know that dark energy and dark matter contribute to the expansion of the universe as much as 96 percent, much remains unknown to the researchers about this unseen phenomenon.

"Dark matter and dark matter are probably one of the greatest mysteries in the world of science, and this phenomenon has attracted much interest in the world of science because we still do not really know what it is," said Professor Lahav.

Called as the most ambitious effort of all time, this dark matter survey has been started since 2004 and involves 400 scientists from 26 institutions in seven countries.

Then, in the process of making maps, scientists had to take pictures of 26 million galaxies using the Blanco telescope in Chile. To do so, the researchers made the most sensitive camera in the world. The camera has a 570 megapixel specification and the ability to detect galaxy light that is eight billion light years away.

By studying how light can be distorted by dark matter, the researchers can calculate the distribution and amount of dark matter, as well as the dark energy in the universe.

The result, the universe consists of ordinary matter of 4 percent, dark matter 26 percent, and 70 percent dark energy as found previously.

However, these findings have not satisfied the thirst of researchers. Therefore, not all galaxies are included in the observation. The plan, DES will spend the next four years to re-collect data.

"Once we have a full survey of 300 million galaxies and a thousand supernovas, we might be able to give input to the new Einstein to tell us what all this means - why is the Universe made like this?" Lahav said.
