Would you rule out the possibility that God created the universe with time/light in place ?
Does “Dark Matter/Dark Energy”, need to exist ?
Do you know why it’s called “Dark” ?
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.)
