Even with regard to their theories on the origin of the universe, Nachmanides’ commentary on Genesis says that originally, the entire universe was a ball of potential, in which both darkness and light were compressed and indistinguishable. That could be interpreted as Big Bang theory, when G-d took that ball of chaos and started unpacking it, and just as the Light was more than mere conventional light, and the true Light was hidden away for the righteous after the end of days, so, too, the darkness might be something more than conventional darkness, maybe even “dark matter”. Could be. Maybe the blind scientists just groped around on the proverbial elephant until they gave it a hand job by accident. Ewww. Anyway. Dark matter. Yeah.
Dark matter. In the Bible, Paul said. “For now we see through a glass darkly...”
And we know nothing is at it APPEARS.
For all I know the dark matter is the illusion.
