"Dark matter" is a place holder for whatever it is that appears to be affecting gravity in large-scale structures like galaxies and galaxy clusters.
We don't know what it is, regardless of what you believe.
Except that we have good reason to believe the cause of this excess gravity is matter....why? Because everytime we observe gravity and we know its cause...it turns out to be matter/energy.
And I have observed more than just computer simulations. The game Chinese Whispers is an evolutionary system which requires an intellect.
