A new study has confirmed that there is most-likely dark matter within the Milky Way and that this dark matter could very likely be causing the light halos that are seen around the edges of the galaxy. While little is known about dark matter, it is estimated that it takes up a significant portion of real estate in space.
Visible matter takes up a very small portion of all the matter that exists in space, so it’s important for scientists to begin understanding where this dark matter is, and what it exists for. However, that has proven to be a rather difficult question to answer. Scientists haven’t made a ton of ground on discovering where dark matter exists, or why it exists. Rather, they have been left making a lot of assumptions since the actual discovery in the 1970s.
Since scientists have been able to figure out though with the most-recent findings that dark matter does have a role in keeping stars and gases in check, and ensure that they continue rotating, it begs further questions about what dark matter is. Doctor Miguel Pato of TU Munchen said, “We know that dark matter is needed in our Galaxy to keep the stars and gas rotating at their observed speeds. However, we still do not know what dark matter is composed of. This is one of the most important science questions of our times.”
However, with the addition of knowledge that dark matter might have a role in stars and the pulling of gravity, it’s worth noting that dark matter might have some light qualities to it. Specifically, it’s the suggestion that particles of light within the substance of dark matter might be scattering away from the center of the molecule before they’re actually visible. If a process like this is taking place, then dark matter would be a misrepresentation – but only partially.

That would suggest that dark matter could hold a number of different states, depending on what it is interacting with. However, it’s simply too early to predict for sure, and ultimately what scientists are going for now is an understanding of where dark matter is in the universe, and what role it plays in that universe.
