A research conducted by astrophysicists has confirmed that dark matter really does exist in the cluster of galaxy in space. By observing multiple collisions between huge clusters of galaxies, the scientists, who published their report in Science Magazine, witnessed dark matter coasting straight through the turmoil.
Dr Richard Massey from Durham University, one of the study's authors, said: "Looking through dark matter is like looking through a bathroom window.
All the objects that you can see in the distance appear slightly distorted and warped."
He added: "We like these collisions because it's exactly what we'd do in the lab.”
"If you want to figure out what something is made out of, you knock it, or you throw it across the room and see where the bits go."
Earlier observation of the “Bullet Cluster” – a bust up between two particularly big groups of galaxies demonstrated the lack of interactions between dark matter. However, the new survey concluded that there was even less interaction than the previous work allowed for.
"In all of these collisions that we've seen, it just seems to go straight through. And now we've seen loads more of them, we would have been able to detect any deceleration of this dark matter, if it had interacted in the ways that most theories predict," Dr Massey said.
