Do you think “dark matter” is Satan ?
Interesting question.
No. I don’t.
I do not think satan is that pervasive in the least.
There’s the Scripture about people looking on the measley personage who was satan and being shocked that such a puny bloke could do so much damage.
His major power is getting people to believe his lies.
And there’s the Scripture about God hiding Himself in darkness—a real mystery that one.
I suspect that dark matter will turn out to have been one of those things God threw in to mystify mortals so we didn’t figure out too much too quickly.
But that’s likely amiss, too.
Thx for the honor of your question.
