Dark Matter
- 1. Kyle G Dark Energy & Matter Dark Energy & Matter Throughout the universe, there is nothingness; or at least, that’s what we thought. Over time, scientists have been studying the facts of the universe and seeing whether or not the universe is made of a special matter called dark matter. Scientists believe that there is not “nothing” floating around out in space. Whether it be invisible or not, they still believe that it is there. Although we cannot prove it yet, this is a theory that most people do believe to be true. Dark matter is in which scientists think that there is a certain type of matter in space. For decades, people thought that space was just as it was named; space. Though, some scientists have been thinking that it is highly unlikely for there to be “nothing” there. This is where they came up with the theory of dark matter. Dark matter is a type of matter that is not made of atoms and does not interact with normal matter and does not send out electromagnetic waves. Another type of dark matter is one in which it is made of neutrinos. These are only visible by their gravitational pull and them being pulled toward other things. Sometimes, this form of dark matter can undergo something called annihilation. This in which they break down and make a by-product called photons. Photons are the basic unites of light. They are elementary particles and the quantum of electromagnetic fields. Dark Matter also helps with the expansion of the universe called dark energy. Dark energy s what scientists believe is helping or causing the expansion of the universe. Dark matter is about 74% of the universe. When the dark matter gets to the rim of the universe, it stays there. When enough of it gathers, it is too much for the rim to handle and it explodes and thus the extension of the universe. Scientists think that this is happening at an accelerating rate. Scientists believe that there are two types of dark energy. There is cosmological constant which is dark matter with a humongous amount of density that fills space tremendously and there is scalar fields which is

Since there is no way to explain anything about dark matter or dark energy, scientists are still making high precision instruments in order to study further. Overall, dark matter is something nobody can see, hear or anything else. It is not normal matter and does not send out electromagnetic waves like regular does. Yet, when it comes down to the creation of our universe, scientists have never been closer. Since there is a lot yet to be discovered, there is nothing we can prove about it. Scientists have only made theories, and now it is time to prove one.
