Properties Of Dark Matter

Dark matter doesn t exist it is extra gravity at low accelerations that is spoofing dark matter the overall density in the universe is measured to be about the equivalent of 2 proton masses per cubic meter and in the solar system higher at around 1 3 of a proton mass per cubic centimeter. The invisible matter that we can t detect is called dark matter the swiss astronomer fritz zwicky first used the term dark matter in the 1930s. He studied the so called coma galaxy cluster and specifically how fast it revolves.

Properties of dark matter. Roughly 70 of the universe is made of dark energy. What is dark energy. Formation of stable halos by collisional fluids with very low mass particles appears as the most probable interpretation while halos formed by high mass particles left over from a hot big bang can scarcely explain the observed density distributions. Dark matter which makes up about 85 of the mass in the universe is more than simply dark.

Neither electricity nor magnetism affect it. More is unknown than is known we know how much there is and we know some of its properties. Dark matter is a form of matter thought to account for approximately 85 of the matter in the universe and about a quarter of its total energy density. Dark matter makes up about 25.

Currently the only clues it gives us are through the gravitational pull it exerts on the normal mass that makes up the objects we can see like stars and planets and us. Clusters are like merry go rounds. Observations of density profiles of galaxies and clusters constrain the properties of dark matter. Their speed of revolution depends on the weight and position of the objects in the clusters like the weight of the objects.

The rest everything on earth everything ever observed with all of our instruments all normal matter adds up to less than 5. Other than that dark energy is a mystery but an important one.
