In the deepest recesses of space, astronomers have finally explained three perfectly identical galaxies. Dark matter has multiplied the image of cosmic triplets. They are just one galaxy. In 2013, the galactic counterparts were discovered by accident by the astronomer Timothy Hamilton of Shawnee State University in Portsmouth, Ohio. Two galaxies identical galaxies were found by Timothy while analyzing data from the Hubble Space Telescope. One is the mirror image of others sitting right next to each other in space.
The exact shape can be seen in the two images and having the same star-flecked galactic centers. The dark parallel lines streaked the two. Timothy spotted the third galaxy not far above them; the mystery only deepened. The galaxy was identical to the other two galaxies. Timothy and his colleagues, after eight years of speculations, have finally hit upon a satisfying explanation. In the journal Monthly Notices of the Royal Astronomical Society, the explanation was published on May 17. The eerie cosmic clones are the same galaxy, located 11 billion lights years from Earth. But the gravity of a massive concentration of dark matter is bending the light from the distant source into three images.
Dark matter is an invisible and mysterious substance. It is said to make up most of the universe’s matter. It is because of the glue that galaxies doesn’t fly apart, is believed by the scientists. How massive objects warp the fabric of space-time is explained by Einstein’s theory of general relativity. According to Einstein, unseen force doesn’t produce gravity. But it is simply the experience of distorting in the presence of energy and matter and space-time curving.
How this curved space sets the energy and matter move rules. In these galactic triplets, light travelling through a highly curved region of space-time travels in a curve, warping and twisting through a giant funhouse mirror until it emerges at three exit points as three perfect copies. Close to the image, looking at the region, the researchers were able to identify the reason behind the unusual lensing effect. A dense blob of dark matter belonging to a cluster of galaxies can be seen. It is situated 7 billion light-years away from Earth and between Earth and the galaxy whose light was bent.
To calculate the distribution of this dark matter specially designed computer program was used by the physicists. The three images of the galaxy were seen stretched, and how it happened was studied by them. The images what they appear now is because the dark matter would need to be smoothly distributed across the light-bending galactic cluster. This result helps to explain the pictures. It also helps to understand how dark matter may be dispersed throughout the universe. The physicists knew that some of the matter was dark, but they didn’t realize the constituent particle. So the behavior is not known. What is known is that it has mass and is subject to gravity. On the clumping or smoothness, the significance of the size limits will give some clue what the particle is made of.
