Scientists have long been studying that thing called dark matter. Now with the cluster collisions in the galaxy, a new light dawns in the quest for learning more about the dark matter.
Forbes released a slide show of images courtesy of the Hubble Space Telescope. The images featured 72 galaxy clusters such as the Abell 370 and Abell 2744. In the photos, dark matters are also found interacting with each other.
From the photos, the idea of the dark matter is still vague. Based on existing theories on the dark matter, it is said to take up most of the space in the universe and no theory has been well justified. However, with the research of the École Polytechnique Fédérale de Lausanne (EPFL) and the University of Edinburgh, the behavior of the dark matter was studied across galaxy cluster collisions and this actually questions one of the existing theories on the dark matter.
According to an article in Physics, dark matter has been interacting in space through gravity. It is also said to speed up galactic motions. Research also shows that just like the universe, galaxy clusters are actually composed of 90 percent dark matter which makes it more interesting to be studied upon.
EPFL's David Harvey and his colleagues' study actually revolves around the same image slide slow of the 72 galaxy cluster collisions. Through their research, it was found out that each galaxy has its dark matters and when the galaxies collide, this becomes an opportunity for the dark matters to interact.
Through their research, they found out a lot of interesting data about the dark matter. First, they discovered that when galaxy cluster collides, dark matters just pass through each other and don't truly interact at all. Harvey and his team are still continuously searching for clarity on the topic of dark matter. Their study also tries to know if dark matters are only composed of dark protons.
