you got the right answer
but
don't know why
Dark Matter as seen with the Hubble Space Telescope: https://en.wikipedia.org/wiki/Dark_matter#/media/File:COSMOS_3D_dark_matter_map.jpg
Dark Matter is undifferentiated material which has no atomic bonds, this would make it of no particular substance. In other words, it is Nothing. And if you are willing to accept it, it is primordial, and God's store house for creating the universe from "Nothing."
Do you any idea about Creation ex nihilo? Does it bring any relationship with quantum mechanics?
That is a map, not a photo, of dark matter. You can't photograph dark matter. It's in the name.
I said it could be seen with special equipment.
It cannot be seen at all.
It's presence can be deduced by analysing the statistical pattern of apparent shapes of distant galaxies and computer modelling the structure of the dark matter until it produces distortion patterns similar to what is observed.
