As the Creator, he could have. Do I think he did? Hell no. It's not logical. Yet...it almost appears that way, doesn't it? Something for us to explore, and that's not a bad thing, is it?
Does dark matter/energy *need* to exist? Apparently, it does. Life has taught me that things exist for a reason. Our problem: we don't understand the reason. Again, life and history teaches us to be patient, we'll figure it out. We used to think we didn't need tonsils. We used to cut out stomachs over and over again to "cure" an ulcer.
Yes, I know why it's called "Dark." It's virtually undetectable using any instrumentation and sensing we currently have available, as it doesn't interact with anything in a significant way, or at all. Were you being condescending in asking me that, or serious? ;) (I already know.)
Yes, I know why it’s called “Dark.” It’s virtually undetectable using any instrumentation and sensing we currently have available, as it doesn’t interact with anything in a significant way, or at all.
That’s not why it is called “Dark”.
It’s called Dark because it is “Unknown”. It is advanced out of necessity to fit their models.
There are plenty of theories and millions of dollars being spent on the detection of this. When or if they do detect “Dark energy/matter”, it will no longer be Dark.
It only exists out of a theoretical necessity.
Without Dark Energy/Matter, everything falls apart.
Consider the claim in Isaiah 45:7 made by the One Who also claimed to be the Creator:
"I form [shape] light and I create darkness."
Unsurprisingly, the universe was dark until inflation and expansion dropped the temperature to 3,000 degrees Kelvin. Then protons and electrons were able to bond and form hydrogen -- and photons were freed to propagate as EM radiation.
...and God said, "Let there be light"...
