Dark matter just means something we have no proof exists but it would be whatever can explain the way everything else is behaving.
Kind of interesting to see “scientists” make something up and talk as if it really exists.
And while they are at it, the massive black hole they say is at the center of the galaxy, might not exist.

According to the present state of science, almost all universe (except for about 5%) is made 50-50 by dark matter and dark energy.
Things we really have no idea what they are!
In summary, scientists basically know nothing!
Honest scientists will admit that, but there is the minority of know everything pseudoscientists who are giving science a very bad name!
“This Dark Matter don’t go to Aintree!”
