Out there, beyond our galaxy and everything we can see with our naked eye, there is another world called Triangulum II. Triangulum II is another galaxy, less hospitable to life than the Milky Way ever was or will ever be. Scientists have approximated that there are only 1,000 stars in this galaxy, quite a small number if we think that our home world houses approximately 100 billion. Astronomers say that Triangulum will never see another new star ever again, but there is more to it than that.
What baffles experts is that this galaxy might harness more dark matter than they have ever seen, or that should exist in any living galaxy and scientific papers are trying to explain why this massive concentration of dark matter might be responsible for the low number of stars that make Triangulum II visible at all.
For those who are not familiar with dark matter, it is the opposite of matter, of course, but it does not abide the same rules as matter does in terms of interacting with light. Matter absorbs and interacts with light, giving scientists details regarding the entire process. Dark matter does not interact or absorb light, but it does bend it in a rather unusual way. This is what makes dark matter a fascinating subject for astronomers and physicists alike.
Experts want to find out to what extent dark matter interacts with the whole Universe, but the results are highly ambiguous. It is widely believed that there is not a lot of dark matter interfering with the mechanisms of the Universe, but there is enough out there to drive scientists mad with curiosity. Triangulum, on the other hand, might be exactly what they were looking for.
A galaxy, just like any other, has a mass which is given by the amount of matter and dark matter. While matter usually reflects the majority of a galaxy’s mass, the same cannot be said about Triangulum. In fact, the theory goes that dark matter might be in fact the main source of mass in this galaxy, which explains why there are few stars to begin with.
There is another world called Triangulum II out there, which might as well be the darkest and most dangerous place in the Universe and we have just managed to discover it. Who knows what we will be able to find out about it next.
