I read dark matter makes the stars in a galaxy to move about a same orbital velocity.
Why isn't this applicable to our solar system?

It IS applicable to our solar system. Why do you think it is not? Our solar system (the Sun being "the star" in question) orbits the center of the Milky Way in a way that is different than what it would do if there were no dark matter. Of course, this is totally aside from the fact that if there were no dark matter there most likely wouldn't BE a Milky Way, but that's a separate issue.Space Dragon said:I read dark matter makes the stars in a galaxy to move about a same orbital velocity.

Black holes attract all matter, dark or otherwise. As far as is known, dark matter acts gravitationally no differently than normal matter.Space Dragon said:Then does a heavy object with more mass like black holes warp more dark matter towards it?
Regular matter, when it comes near a black hole, collides with other matter and forms an accretion disk before falling in. Dark matter doesn't do that.Space Dragon said:I know dark matter is unaffected by electromagnetism..But shouldn't it interact with gravity and thereby get attracted to the black hole?
And dark matter is present everywhere so why isn't direct impact possible?

Dark matter is a type of matter that makes up about 85% of the total matter in the universe. It does not interact with light, making it invisible to telescopes and other traditional methods of detection.
2.Dark matter does not directly affect our planets, as it does not interact with light or other forms of matter. However, its presence in the universe does have an indirect effect on the motion and formation of planets through its gravitational pull.
3.The gravitational pull of dark matter is responsible for the formation and structure of galaxies, including our own Milky Way. This gravitational pull also affects the velocity of objects within the galaxy, including planets, causing them to move in a similar motion.
4.Yes, there is strong evidence from observations of the rotation of galaxies and gravitational lensing that supports the presence and effect of dark matter on the motion of objects in the universe, including planets.
5.Studying dark matter allows scientists to better understand the formation and evolution of galaxies, including our own. It also helps to explain the observed motions of objects in the universe and provides insight into the distribution of matter in the universe.
