So there are a few things I have learned about girls (and by a few I mean I've learned almost everything about women). They love flowers, chocolate, sweet little notes, and one other thing they love is looking at the sky. Who knows why staring at a blank looking canvas with little white dots is so fascinating and romantic, but to them it is (so men take note). There are many different types of articles written on these supposed spots of dark matter, however some are more reliable and science oriented than others. N. G. Kogoshvili, G. A. Malasidze, and T. M. Borchkhadze have written an academic paper titled POSSIBLE DARK MATTER IN SPIRAL GALAXIES OF THE COMA CLUSTER in which they explore dark matter in galaxies. And while i'm not trying to be girly, the shit is kinda cool.
Dark matter is basically a hypothetical form of matter that is detected by its gravitational effects on other matter you can see, it actually makes up the majority of universe that is visible to us. The reason for this is due to its gravitational pull, it almost makes it seem like the space does not exist but in reality it is in an almost 3-D form. To calculate exactly how much of this dark matter there is in each galaxy scientists looked at the maximum rotation velocity, luminosity (how much that stuff glows) which is emitted in the form of energy photons, and its total angular momentum, or at what angle it rotates. All these variables are compounded and many long complicated calculations are done. Scientists can come to the conclusion that galaxies with the lowest luminosities have higher mass to luminosity ratios, or more stuff for how much it glows. Therefore it has also been shown that galaxies with these higher ratios have way more dark matter that fill them up, compared to how big we think they are. All this is based off how much light they give off and in what way you can see the photons of light. This also proves that the majority of the dark matter is contained in the middle of the spiral galaxy, where the ratio is the highest. For those of you who dont know what a spiral galaxy is, it exists in the shape of a flat rotating disk with a bulge in the center containing the most stars followed by a halo of dimmer stars around the outside. Finally the angle and momentum of the galaxy play a role in determining how much matter to space ratio the galaxy has; verifying something must fill up the skies.
So for all of you who didn't quite grasp that all the scientists are trying to figure out is how much of the awesomely strange dark matter is in the universe by doing complicated math equations; which no socially acceptable human being should understand. What you should take from this article is that a first edition journal was recently written proving the amounts of dark matter in galaxies based on its rotation, momentum and luminosity. These dark regions are still constantly being studied and recalculated, for the universe is always in continuous motion and every so slightly changing its course.
So whenever you’re taking talking to a girl (or if you need a smooth conversation starter) just pull this little fact out. It is guaranteed to get you started on a long conversation about space and its dimensions, which hopefully ends all the way back at your door.
