Anyway, dark matter is defined as something that exerts a gravitational force, but not the nuclear or the electromagnetic force. Well, what I've
learned about the term gravitational force(field) is that it basically means to exist within space-(time)(for example, matter is defined as something
that has mass and occupies space, mass is defined as "something" that exerts a gravitational field. In other words, in order for
"something"(energy, which could be said to be nothing) to become "something more solid"(matter), it has to exert this force and occupies space.
Now energy itself doesn't occupy space, therefore, in order for it to exist and qualify as matter, it has to exert this force, by curving the space
around it around itself. When it does, it now "becomes" matter(when in fact, it's still just energy "mixed" with space) and "occupies" space.
In other words, energy turning into matter is basically energy that exists outside of space-(time) turning into energy that exists within
space-(time), by exerting a force to space.
Essentially, the gravitational force or "curved space-time" force is the "default" force, in order for any type of energy to exist within
space-(time). Since it doesn't interact with the other three forces, this must mean that either its structure is entirely different, or that it
exists simply as (dark) energy, providing the force(or "mass," remember, mass can basically be defined as energy that exerts a gravitational force)
for the galaxies by curving around itself, without needing to form any fundamental particles.
