Dark Matter or Spin?

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 alot more matter then there was showing. So therefore Dark Matter was created. If a fabric of space/time exists such as Einstein predicted and a massive object such as 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? 

When we were running our calculations for gravity to matter within our galaxy and universe, did we account for the spin of these massive objects also? Or did we only account for the mass of these objects.

I believe the spin of these massive objects throughout space, from moons to suns will all have an effect on that final calculation. This is excluding the fact that combined it would be enormous. We would see the increase, in the gravity or bent space of our galaxy and of the universe, as we are supposed to and do.

If you put a bowling ball on a sheet and stretched it out it would cause a dip in the sheet. Now if you spun that bowling ball it would pull on the sheet causing even more of a tension effect. This brings in another interesting new theory of the elasticity of the fabric of space/time. How tight is the sheet being held and can that be deduced from the spin?

My suggestion of what Dark Matter could simply be is just the spin of these massive objects in space. Especially when all those objects are combined. That's going to have an effect. Also the new idea of the fabric of space/time and it's elasticity...currently. Could that elasticity change and what would cause that, maybe dark energy ;).

What are your thoughts on this? Respond in the forum, under physics. I'm pretty sure you can't miss the topic "Dark Matter or Spin?".
