After years and years of research, debates, and studies, European astronomers may have found dark matter. Several years ago a satellite has detected and abnormal energy which may be dark matter. According to the researchers, the Universe consists of 5% of ordinary material (atoms), 23% of dark matter, and 72% of dark energy.
Although dark matter and dark energy are a mystery, the astrophysicists have somehow calculated what you can find in the cosmos. Until now dark matter was observed indirectly thanks to the gravitational forces exerted on the visible matter. However, the European astronomers believe that dark matter is that mysterious energy signal that was detected by a satellite.
In the meantime, the Universe remains an infinite puzzle, and astronomers can only argue what can be found in the cosmos. Some say that darl matter is Universe’s new dimension, some say that the dark matter consists of a different type of particle called WIMPs, while others are convinced that the dark matter is based on sub-atomic or supersymmetric particles. Considering these three aforementioned theories, the hypothesis of WIMPs is the most plausible – WIMPs stands for Weakly Interacting Massive Particles, and it is said that these new particles interact so weakly with visible and regular matter that it doesn’t generate light-emitting phenomenons, but so far nobody presented conclusive evidence.
According to this new study conducted by a team of researchers at the University of Rome Tor Vergata, the dark matter may have been detected by the orbiting satellite called “Pamela”. The leader of the team, Piergiorgio Picozza, says that they found a huge number of positrons in cosmic rays which is anomalous.
“Some scientists think this is dark matter, while others think we have to study contributions from other positron sources. We need much more verification, which can come from other observations,” said Picozza.
Is it possible that astronomers may have found dark matter? Or dark energy? Or that “stuff” that holds the Universe? Is this just a new hoax theory? We really need the answers for these questions because we need to know more about the Universe. Why? Well, the human race has an urge for knowledge.
