No they’re not. You got not one spec of supporting evidence. Dark matter has been searched for for over 80 years and zilch, zero, nadda.
What you mean to say is they are using the physics for solids, liquids and non-ionized gasses, which are 99.9% accurate in the solar system. Then apply that physics to a universe 99.9% plasma (ionized matter), get the wrong answers to the theory that was just 99.9% correct, and instead of using the correct physics (plasma physics) insert Fairie Dust to correct for using the wrong physics.
What is Dark matter or energy? You haven’t a clue, can’t tell me in the slightest and think it’s scientific. Laughable.
Agreed, discussing dark matter or dark energy without access to said entity and discussing its properties seems rather pointless and silly.
Agreed, you say dark matter and Energy, but without being able to show there actually exists any such thing....
Pretty meaningless....
Agreed, just like not having any dark matter or dark energy to actually have something to investigate and label. Just having Fairie Dust doesn’t cut it.
