Nevertheless, the existence of dark matter has been widely accepted henceforth, and research into it is ongoing. Astronomers have recently discovered a galaxy without the existence of dark matter(Shelton). Dark matter cannot actually be seen or detected itself, but, as Zwicky found, it causes immense levels of gravity. This newly discovered galaxy has only the normal amount of gravity you would expect to find due to its stars, planets, and general cosmic junk, unlike every other galaxy we’ve researched, which has a much greater gravitational effect than can be attributed to the mass of the known matter in any particular galaxy. Jim Shelton quotes Pieter van Dokkum, the leader of the team which discovered this galaxy, “This invisible, mysterious

It challenges the standard ideas of how we think galaxies work, and it shows that dark matter is real. It has its own separate existence apart from other components of galaxies”. The fact that a galaxy exists which prescribed to the Newtonian rules of physics without the presence of dark matter proves that it is not a flaw in the laws of physics that creates the gravitational problem. Essentially, the fact that a galaxy exist which definitely does not contain dark matter (or at least not measurable levels of it) proves the unusual gravitational forces observed in every other observable galaxy must be caused by dark matter and not by a misunderstanding on our part on how gravity works outside of our planet.
Going forward, the majority of modern research surrounding dark matter discusses what exactly it is. We can observe its significance and its impact on the universe but have no concreate way to measure it. Drs. Lydnden-bell and Gilmore explain that there are three possibilities, “All of it is ordinary(baryonic) matter, all of it is some other kind of (non-baryonic) matter, or some of it is baryonic and some is not baryonic”(vii). Baryonic matter is matter that is made up of protons and neutrons. We …show more content…
A possible connection between primordial black holes and dark matter has been found. Unlike dark matter, black holes have been observed, although they too are surrounded by false imaginings of peril. Gates explains “A black hole of any size is formed whenever too much mass is compacted into a very small space. The definition of very small depends on the amount of mass you have to work with. To create a black hole with the mass of the Earth, you simply need to cram the entire Earth into a ball about two-thirds of an inch across”(113). Gravity is always pulling things together, black holes are formed when the force that is opposing the pull becomes weaker than gravity, and the mass is pulled inwards. Primordial black holes are black holes that formed during the first seconds of the universe’s existence. Because primordial black holes are so ancient, they are also incredibly prevalent, so it is reasonable to conclude that primordial black holes, or the aftereffects of them, densely occupy the universe. Black holes are gravitationally massive in a way that is similar but not exactly the same as dark matter. And, although we can detect black holes, we can’t actually see them. This is because a black hole will “continue to pull the mass inward on itself past the point of no return, creating an object of infinite density, a warp in spacetime so
