Milky Way and Giant Black Hole

Our Galaxy is called "Milky Way" because of its shape,
Have we ever thought why it looks like this?

Here is the answer based on my thoughts

Scientists have discovered a black hole in the heart (center) of our galaxy. A black hole is a giant star beast having very strong gravitational force spinning at very high speed exerting force on stars. As the black hole is present in the center of our galaxy spinning and exerting gravitational force on stars. So the stars also begins to rotate and we know that galaxy is a mixture of stars, dust, planets etc.

So according to my point of view, the spinning of black hole is responsible for our galaxy to be called Milky Way.
