Dark matter

Dark matter and dark energy are perhaps the biggest mysteries in the universe. Dark matter makes up 26% of the universe, dark energy makes up 69% of the universe, and ‘normal’ matter- everything visually observed in the universe- makes up only 5% of the universe. Dark matter and energy are thought to be explanations for various phenomena that have been observed in deep space. Dark matter is matter that cannot be detected by its absorption or emission of electromagnetic radiation. Scientists currently have a very dim understanding of exactly what dark matter is, but one theory is that dark matter is made up of exotic particles that don’t behave like ‘normal’ matter, but still exert a gravitational pull. They believe that dark matter exerts a gravitational pull because the amount of ‘regular’ matter in the universe, and ‘normal’ matter…

Dark matter is matter that cannot be directly seen because it does not interact with light. This mysterious matter makes up the majority of mass in a galaxy. Although we cannot see dark matter we know that it is out there because we can see it effecting the motion of the stars in a galaxy and gravitational lensing. The first piece of evidence for dark matter is in the way we have observed galaxies moving. You would likely expect their behavior to replicate that of the Sun and the planets, with…

Dark matter and dark energy are phantoms of the scientific community. The scientific community has tried to detect dark matter for decades. Hairy dark matter could be the key to the secrets of the Big Bang and the events that occurred afterwards. Condensed filaments of dark matter, hairs, in our galactic neighborhood could be used to gather incredible amounts of data that was previously unavailable to us. Hairy dark matter is a type of dark matter, formed by the gravity of space objects, that…

Dark matter leaves astronomers and physicists baffled as to what it possibly could be. Scientists design experiments to attempt to figure out what it is, but no one truly knows what composes dark matter. Physicists are so interested in understanding dark matter because it accounts for the formation of the Universe, as observable through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word…

Dark Matter and Dark Energy Casson VanDervoort Northview High School  Dark energy and dark matter are commonly found to disprove common knowledge in the world of science but still, these two forces are unknown and untapped. Both dark energy and dark matter are commonly referred to as one another but, in fact they’re different. The two are mostly found together but, dark matter may have been found to be linked to primordial black holes. One may ask, “What is dark matter and energy and…

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…

Dark matter makes up roughly 23% of the universe, and is thought to be the cause of its expansion. Dark matter was first proposed by Swiss astronomer, Fritz Zwicky when he noted that galaxies are flying away to fast. He noticed that galaxies are flying away to fast that they should fly apart, dissolve under Newtonian Laws of Motion. He thought the coma cluster may be saved if it were 100x more matter than you can see. Theres two possibilities left. Newton was wrong or something was missing. …

One concept that has interested is dark matter and dark energy. Dark matter is the thing that makes it possible for galaxies to exist. When astrophysicists and cosmologist calculated why the universe is structure the way it is, it became clear that there’s just not enough normal matter. The gravity of the visible matter is not strong enough to from galaxies and complex structures. The starts would more likely be scattered all over the place and not form galaxies. Therefore, cosmologist concluded…

What are Dark Matter and Dark Energy? Introduction: To start with, Dark Matter is invisible material that permeates the galaxies. It exerts a gravitational influence on the stars causing them to deviate from Newton’s and Kepler’s laws. Dark Matter also affects members of a group of galaxies. The nature and composition of the Dark Matter are unknown. In space there is a lot of totally empty space, the vacuum, which contains energy. This energy is variously called Dark Energy and also may be…

immediately have two distinct phrases come to mind: Dark matter and dark energy. From being mentioned in groundbreaking scientific journals and television and movie series’ to even this essay you are reading, dark matter and its existence has made quite the impression on scientists, documentarians and aspiring students.…
