If there were much more of it around, it would affect the cosmological expansion. Perhaps it could be detected this way.

The distribution of the DM in space now is very much non-uniform. Since it doesn't clump, was its distribution as non-uniform soon after the BB?
-
Is it necessarily so? If it could interact electromagnetically by completely reflecting an EM radiation it wouldn't emit a thermal EM radiation, would it?
-
Many think that it interacts not only via gravity but also weakly, i.e. made of WIMPs.

I don't know why it's called dark, but not interacting electromagnetically makes it rather transparent than dark.
-
We also know that it was there by the time of "recombination", about 380 000 years after the Big Bang.
-
We know where it is and how much of it is there. We don't know what it is.

Nice. Except the very last statement. That is a kind of "wishful thinking" fallacy.
