The reason we posit it's there is because we detect it. Agree with Florin_Andrei. If they had just named it skotonic matter or something, no one would have these objections. It's a working model with growing evidence to support it. That's it. And if weird types and states of matter that we haven't been able to detect directly is really an issue, I have bad news about virtually all our knowledge of particle and stellar physics...
