Hypothesized DM really doesn't interact with light at all. DM doesn't reflect it, refract it block it or absorb it.
"Dark matter does interact with gravity..."
is kind of misleading.
DM solely & exclusively creates gravity,
but absolutely nowhere do we see DM responding to gravity. Not its own or any other gravity,
which if you think about it is odd because gravity is the shape/geometry of space-time itself.
DM is/would-be a one way gravity inducer,
with no demonstrable inertia.
The absolute and only evidence that might imply DM is behavior of visible matter with what appears to be gravity.
"...we need extra mass to explain [galaxies'] rotation."
No, you need gravity as one possible means of explaining galaxies' rotations.
DM forms into 'halos' that very neatly end up centering symmetrically on galactic centers,
all happening with invisible 'dark physics' that have zero direct effects on any visible matter.
The hypothesized quantity of DM in galaxies has an unexpected tight correlation with the specific sizes of each of their central black holes.
?
Static clouds of gravitons or unknown expansive time dilation fields, possibly radiating from the central black hole of galaxies might be a better means of grappling with the observed effect, rather than leaping to invisible, virtually undetectable matter?
Well, to each their own.
The 3 miliion physicists of the world and Questioner will never figure out what dark matter is until they come to understand that garvity generation and dark matter gravity generation are the direct function of mass and the rate at which the matter particles of the mass heat up!!
The undeniable proof that gravity generation and dark matter gravity generation are the direct function of mass and the rate at which the matter particles of mass heat up is in the given facts below and my arguments of the given facts!!
The Proofs About My Suggestion That Gravity Is The Direct Function Of Mass And The Rate At Which The Matter Particles Of The Mass Heat Up!!):
1): Take Our Own Sun As An Example Of Gravity Generation As Our Sun’s Matter Heats Up!!):
A): We Are Given That Our Sun Formed From The Collapse Of A Molecular Hydrogen-Helium Cloud At 10 Degrees Kelvin!!
B): We Are Given That For The Past 5 Billion Years That Our Sun Has Been Heating Up And Generating Gravity!!
C): We Are Given That Our Sun Will Heat Up By 6% Per Billion Years For The Next 5 Billion Years While Generating Gravity!!
D): In 5 Billion Years); We Are Given That Our Sun Will Start Cooling From 7777 Kelvin To 3000 Kelvin While Net Emitting The Stored Anti-Gravity/Dark Energy Stored Inside The Nucleon, Electron And Neutrino Indestructible Mass-Energy Vessel Permeable Hovering Sacs In The Form Of Compressed GP1 Aether Particles That Were Stored During The 10 Billion Years That Our Sun Heated Up And Generated Gravity Blowing Off Half Its Mass Leaving A White Dwarf Remnant About The Size Of Earth At 200,000 Times Earth Density!!
E): One Proof That As Matter Cools And Net Expels GP1 Aether Particles); Dark Energy Is Released Is The Red Giant Phase Of Our Sun’s Life Cycle And All Red Giant Stars!!
2): From Observations Of Bullet Clusters We Know That Gravity And Dark Matter Gravity Stays With The Star Matter And Dark Neutrino Matter Heating Up From The Radiant Energy Of Stars And Not With An Equal Amount Of Cooling Hot Gaseous Matter Left Behind As The Two Galactic Clusters Separate!!
Above 1 & 2): Coincidence Or Direct Proof That Gravity Is A Direct Function Of Mass And The Rate At Which The Matter Particles Of The Mass Heat Up And That As Matter Particles Cool And Net Expel GP1 Aether Particles); Dark Energy Is Released Like By The Cooling Hot Gases Equal To The Mass Of The Stars Of A Bullet Cluster And The Cooling Gases At 7777 Kelvin When Our Sun Will Begin To Transform To A Red Giant!!
3): From The Discovery Of The DiPole RePeller Void In 2017): We Are Given That Lowering The Energy Quotient Per Cubic Meter In A Void Releases Measurable Dark Repulsive Energy As The Matter Including Dark Neutrino Matter In The Void Cools And Net Expels Compressed GP1 Aether Particles Creating A Void With Repulsive High GP1 Aether Particle Pressure System!!
4): Suggestion): As Superclusters Crunch And Energy Density Per Cubic Meter Increases And As Nucleon Matter In All The Stars And Neutrino Dark Matter Heats Up By Net Compressing GP1 Aether Particles Inside The Matter Vessel Sacs While Reducing The Volume Of Space): We Generate Increasing Low GP1 Aether Particle Pressure Throughout The Supercluster As We Are Given That Gravity And Dark Matter Gravity Will Be Generated By The Reduction In GP1 Aether Particle Pressure Relative To The High GP1 Aether Particle Pressure Of Expanding Voids!!
5): We Are Given That As The Great Attractor And The Shapley Attractor Crunch And Energy Density-Vacuum Energy Increases Per Cubic Meter); Matter Gravity And Dark Matter Gravity Is Generated In The Attractors That Causes The Local Galactic Group, The Virgo Galactic Centric Cluster And The Virgo Supercluster To Be Pulled At 341 Kilometers/Second Towards The Attractors); While The Cooling DiPole RePeller Void With Decreasing Vacuum Energy Per Cubic Meter Pushes Us At 290 Kilometers Per Second Towards The Great Attractor For A Net Total Peculiar Velocity Of 631 Kilometers/Second For Our Virgo Supercluster And Our Local Galactic Group!!
6): We Are Given That Low Air Pressure Hurricane Systems Develop At The Equator And That Hurricanes Intensify From Solar Radiant Heat And Warm Water!!
From The Given Above): I Suggest That The Heating Up Of Matter Particles Results In Low GP1 Aether Particle Pressure That Results In Low Air Pressure And/Or Gravitational Force Is Generated As Potential Dark Energy And Mass Is Stored In Matter Particle Permeable Sacs!!
And At The Earth’s Poles We Are Given That As Matter Cools High Air Pressure Systems Develop As Compressed Net GP1 Aether Particles Pulsate Out Of Nucleon, Electron And Neutrino Pulsating Hovering Permeable Indestructible Vessel Sacs Resulting In High GP1 Aether Particle Systems That Transform Air Particles To High Air Pressure Systems As They Cool!!
7): Side Note): If You Look At A Picture Of A Low Air Pressure Hurricane System On Earth And A Picture Of A Low GP1 Aether Particle Spiral Galaxy System In Space Side By Side); You Will Find The Pictures Are Nearly Identical Because Both Are Low GP1 Aether Particle Systems!!
I welcome any and all questions about any and all of my posts, theories and associated proofs!! If you should question, you will learn about gravity, dark matter gravity and dark energy mysteries as given by modern physicists along with logical easy to understand physical mechanical explanations based on given facts!!
Talk More Soon!! Have A Great Day!!!
