First Most Complete Universe Map Has Been Created

Avid physics-lovers, rejoice. Scientists have recently worked out the most complete map of the universe. The map is a three-dimensional one, spherical in shape, showing the position and mass distribution of galaxies. What makes the endeavour even more exciting is that it takes motion into consideration.


The movement of galaxies across the heavens can now be traced with the new map; other maps designed in the past do not include motion in the equation, and thus, the new one is invaluable to researchers. The extra details it provides will now help astrophysicists to dig deeper into the universe. The findings have been published in the Monthly Notices of the Royal Astronomical Society.

A great proportion of pertinent questions that have yet to be answered might be easier now to attend to. For instance, scientists might decipher how much dark matter is present in the universe. Furthermore, the distribution of the dark matter can also hopefully be determined. The size, velocity, and distribution of the conspicuous galaxies will aid scientists to find the spots occupied by dark matter.

The map consists of colour codes. Light blue shows the presence of galaxies, light blue to white points at a greater concentration of galaxies, and the red regions represent superclusters of galaxies. Medium blue denotes areas that have remained unexplored.

An expert explains the galaxy distribution as follows:-

“The galaxy distribution isn’t uniform and has no pattern,” said Mike Hudson, associate dean of science, computing at Waterloo.

“It has peaks and valleys much like a mountain range. This is what we expect if the large-scale structure originates from quantum fluctuations in the early universe.”

The map will now have to be improved to magnify the scope for more in-depth research.
