Fascinating. As a non-scientist I will confess that at times I’ve been skeptical whether dark matter exists or if it was invented to make the models work.
Thats because it was invented to make the models work. By definition it cannot be observed directly so it's never been observed directly but this presence of immense amounts of invisible, intangible stuff is needed to make the models fit actual observed phenomena. It might even be real. But currently it's a hypothesis that explains some otherwise catastrophic model issues for celestial mechanics.
But this experiment didn't detect dark matter, it just caught a freak event that that had nothing to do with dark matter and just happened to occur in an apparatus they were monitoring hoping to find dark matter so they saw it.
The answer is probably yes, and yes.
Models die hard.....When will the theorists look for another explanation for the holding together of the universe being that the universe is so old?
Oh...I forgot...it’s settled science...
It's the latter.
Dark matter is a cheat. They just dont make genius physicists like they used to.
