I've skimmed articles/blogs and watched videos around this issue, and the universal consensus is that dark matter and dark energy are two different things >> DM is attractive while DE is repulsive.
LOGIC 1: Dark matter is attractive because it resides/surrounds within an individual galaxy's volume space. On the other hand, dark energy is "repulsive" (it pulls galaxies away from each other) because it is outside the volume space of the observable Universe.
Following this logic, as the universe expands, the dark energy that falls into the space volume of individual galaxies will form part of its dark matter and becomes "attractive".
LOGIC 2: If dark energy is really purely repulsive, then it must have started tearing apart visible matter on the outer edges of the Universe.
Logic 1 looks more plausible to me. Following Logic 1, is it possible that a common yet unknown particle is the source of both DM and DE?
