The mystery of dark matter has been decoded?

For decades, astronomers have been trying to find dark matter - the invisible substance that is thought to occupy a large part of the universe, exactly. A new study, using data from the Fermi space telescope of the US Aerospace Agency (NASA) may eventually provide some answers.

>>>Reveal the first image of dark matter

Professor Dan Hooper and colleagues at Fermi National Laboratory in Illinois, USA have been studying a sign in the center of our Milky Way since 2009. They now believe that signs include the system. Gamma rays with this ultra-high energy radiation collide with dark matter particles.

When particulate matter destroys each other, they release gamma rays into space, which increases the apparent light in the center of the Milky Way. The same discovery in neighboring dwarf galaxies (galaxies smaller than our Milky Way) may reinforce the new hypothesis.

"This is the most convincing sign of the dark matter particles we have ever obtained , " Professor Hooper said.

To validate his findings, Professor Hooper's team had to eliminate other possibilities for signs, including the ability of gamma rays to be produced by a distant crystal star or a fast-rotating star. They found that gamma rays create an active range that spans nearly 10,000 light-years, rejecting the possibility of being a source of emission.

If Hooper's discovery is ultimately correct, it will raise some conundrums about dark matter.

Previously, scientists once thought that dark matter came from a hypothetical particle called "weakly interacting large particle" (WIMP) . However, if dark matter is being formed and collided at the center of the galaxy, it is more likely to be a much heavier particle. This will be suspicious of some evidence obtained from previous experiments on Earth about dark matter.
