So, if you can’t explain something, just say it’s because of Dark Matter.
“Sir, you were doing 50 in a 25 zone.”
“That may be so, Officer, but it’s because of Dark Matter!”
Or
“These aren’t my underwear! Where did they come from?”
“Those are from Dark Matter, honey.”
... and if it’s something you can’t figure out, just say, “Well, that proves there’s a God.”
The same applies to the use of “singularity”. It’s a catchall term for the lack of understanding.
