Dark matter is one of the greatest unknowns in the cosmos, despite being the most important gravitational component. Indeed, dark matter is the most prevalent matter and its bulk has an impact on the design of the universe. It has permitted the construction and preservation of cosmic structures. As a result, understanding the cosmos without knowing its qualities is extremely difficult. However, it only reacts to gravity and not to the other fundamental forces. It is not a weak reaction, but rather the complete lack of direct reactivity with full spin (even in our particle accelerators). Indeed, dark matter is not only opaque to us because it lacks a measurable electromagnetic field, but it also exhibits no nuclear reaction at all. Finally, it appears to be able to influence only wide areas, implying that it lacks concentration. So the only thing we know about dark matter is its non-properties or what it does not do, which is react with our own fundamental forces (save gravity) and cover only enormous areas (big gravitational lenses). As a result, dark matter remains a big mystery. There is, however, a solution if the problem is phrased differently.

Abstract


Dark matter is one of the greatest unknowns in the cosmos, despite being the most important gravitational component. Indeed, dark matter is the most prevalent matter and its bulk has an impact on the design of the universe. It has permitted the construction and preservation of cosmic structures. As a result, understanding the cosmos without knowing its qualities is extremely difficult. However, it only reacts to gravity and not to the other fundamental forces. It is not a weak reaction, but rather the complete lack of direct reactivity with full spin (even in our particle accelerators). Indeed, dark matter is not only opaque to us because it lacks a measurable electromagnetic field, but it also exhibits no nuclear reaction at all. Finally, it appears to be able to influence only wide areas, implying that it lacks concentration. So the only thing we know about dark matter is its non-properties or what it does not do, which is react with our own fundamental forces (save gravity) and cover only enormous areas (big gravitational lenses). As a result, dark matter remains a big mystery. There is, however, a solution if the problem is phrased differently.
