While looking up at the same starry sky, astronomers can see many different things, such as distant galaxies, stars, and even black holes. With the naked eye of ordinary people, it is clear that the mystery of the universe cannot be solved directly. Because according to a consensus among academics, dark matter may account for more than three-quarters of the total mass of the universe. So, can we explain its origin?

Since dark matter cannot be directly observed, scientists must infer the existence of dark matter by reacting to its gravity by other objects in the universe.
A new study by the University of York recently offered a possible explanation for the true existence of dark matter.
The secret of dark matter may exist in a particle called d-star hexaquark, the researchers said.
As SciTechDaily points out, this is a particle consisting of six quarks (also tiny fragments of protons and neutrons).
However, because it is arranged in a “d-star” manner, it is more widely used.
After the Big Bang, scientists say, there may have been a fairly rich “d-star six quarks” that came together.
However, as the cooling process progresses, it may have transformed in large numbers into the fifth form of matter, the Bose-Einstein condensate.
In other words, the super-cold cloud of boson particles may be a viable candidate for dark matter. Professor Daniel Watts, Of york, explains:
The origin of dark matter in the universe is one of the biggest problems in the scientific community. Until now, the field has been blank.
Preliminary calculations indicate that ‘d-star condensate’ may be a viable candidate for dark matter. The results are particularly exciting because they do not need to rely on any new physical concepts.
Looking ahead, other studies of “d-star” behavior may offer other clues — either to support the researchers’ claims or to refute them.
