dark matter manages the universe
What does that mean exactly? Dark matter is part of the universe content. There is no management involved in there.
I do not think black holes are involved
Science will tell us soon whether you are right or wrong :)
dark matter shapes the universe. the stars outside the galaxy rotate at the same speed as the stars in the center. it makes it dark matter. I meant that. absolutely. we will wait and see the innovations👍
Thanks now it is clearer. The rotation curves of the galaxies are not the only (indirect) proof for dark matter. There are also many more today :)
you're right. Science is not stopping. thank you 👍
