No it doesn't. This is the latest example of physicists saying "trust us, we're smarter than you" without any evidence to back up their claims. Gravity has a multiplying effect in planetary and stellar motion, so it is the simplest answer (Occam's Razor). They may be correct and there is a substance called "Dark Matter", but for a collective group of people who shun the thought of an Almighty God, they are rather hypocritical to tell us to just have faith.
Arm-waving is so much more fun when you get government grants!
i know- i was just making a funny
Acutally, go back and read about Vera Rubin:
https://en.wikipedia.org/wiki/Vera_Rubin
She used observation to find “dark matter” in galaxies. All the rest is trying to explain what she observed.
The answer may be as simple as underestimating the amount of rubble between the stars in a galaxy, but, they are looking for actual missing mass.
This hunt is much more scientific than the hunt for “climate change” that no one can observe, or, even define.
Where did they tell you to just have faith?

I wonder why they would bother with this experiment that is fifty times more sensitive if what you’re saying is true.
