Dark Matter May Be Interacting With An Unknown Dark Force
Dark matter is a hypothetical substance that makes much of the mass present in the universe. It can’t be observed directly so, in a sense, it is the mysterious matter.
When scientists have to make its observations, they chiefly rely on detectable space objects. This time scientists have found a clue which can lead to discovery of the composition of dark matter. According to Nature, during a recent study of four colliding galaxies, scientists observed that the dark matter might be interacting with itself under the effect of some obscure “dark force.”
The colliding galaxies in Abell 3827 suggest that dark matter’s interaction with other dark matter is unique as it does not have any effects on the ordinary matter.
“This result, if confirmed, could upend our understanding of dark matter,” hysicist Don Lincoln of the Fermi National Accelerator Laboratory in Illinois told Nature.
The source explains that the dark matter’s self interaction “requires not only dark matter particles but also a dark force to govern their interactions and dark boson particles to carry this force.”
If the scientists validate the occurring of unique interaction of the mysterious matter with further evidences, it would lead them to redefine its identity. Also it would be interesting to see how the new revelation is going to affect the first map of the dark matter created just in the last week.
The map is being regarded as a significant break in unraveling the mystery behind dark matter, and will assist scientists, in great detail, in learning how galaxies evolve.
