Dark Matter was first thought of to supplement why the gravity of our galaxy didn't account for all the visible matter. There had to be a lot more matter then there is. So therefore dark matter was created. If a fabric of space/time exists such as Einstein predicted and a massive object, such as a planet or a star, can bend that fabric and have an effect on it...then why would the spin of these massive objects also not have an effect on it? When we were running our calculations for gravity to mass equals dark matter, did we account for the spin of all these massive objects? I believe the spin of all these massive objects in space will have an effect, an increase, in the gravity or bent space of our galaxy. If you put a bowling ball on a sheet it bends the sheet. If you spin that bowling ball then it will pull the fabric in more giving the illusion that the fabric would have more tension on it. Therefore a suggestion I have is what if dark matter is simply just the spin of these billions of massive objects in our galaxy? Again did we add that into our equation when we did the math?

What are your thoughts on this? It really is just a stab in the dark, no pun intended. But really why would the spin of a massive star not have some sort of major stress on the fabric of space/time. A spinning bowling ball on a sheet does.
