Dark Matter: Some Interesting Facts


☻ Dark matter comprises around 84.5% of the total matter in the universe.

☻ It isn’t made up of baryons, unlike normal matter, which is a combination of protons and neutrons. Dark matter doesn’t interact with electromagnetic forces. It doesn’t absorb or emit light, nor does it reflect it like normal matter. The only way it can be detected is through its gravitational pull on visible matter.

Jan Oort, a Dutch astronomer, was the first to detect the presence of dark matter, in 1932. While studying stellar motions in nearby galaxies, Oort found that the matter seen in the galaxies is quite less as compared to the size of the galaxies.

☻ The ‘missing mass’ problem suggested that, the stars, hot gases, and visible matter in the galaxy clusters accounted for hardly 20% of the total matter in the galaxy. The speed at which these galaxies moved was enough to flow them apart. According to Fritz Zwicky, a Swiss astronomer, these galaxies needed a lot more mass to hold themselves together, considering their speed. This meant that, there was some matter missing to the human eye, that was holding these galaxies together.

    There is evidence of dark matter every time a double slit experiment is performed; it’s what waves.
    occupies three dimensional space. Dark matter is physically displaced by the particles of matter which exist in it and move through it.

    The Milky Way’s halo is not a clump of stuff anchored to the Milky Way. The Milky Way is moving through and displacing the dark matter.

    The Milky Way’s halo is the state of displacement of the dark matter.

    The Milky Way’s halo is the deformation of spacetime.

    What is referred to geometrically as the deformation of spacetime physically exists in nature as the state of displacement of the dark matter.

    A moving particle has an associated dark matter displacement wave. In a double slit experiment the particle travels through a single slit and the associated wave in the dark matter passes through both.

    Q. Why is the particle always detected traveling through a single slit in a double slit experiment?
    A. The particle always travels through a single slit. It is the associated wave in the dark matter which passes through both.

    What ripples when galaxy clusters collide is what waves in a double slit experiment; the dark matter.

    Einstein’s gravitational wave is de Broglie’s wave of wave-particle duality; both are waves in the Dark matter.

    Dark matter displaced by matter relates general relativity and quantum mechanics.
