Hard to wrap my mind around this one. Anyone have any good analogies that fit?

It’s a little better if you can see it.
But imagine a grid with a bomb in it. The bomb explodes at a point and goes outward. The grid doesn’t move. That’s bangs as we’re used to.
The big bang is more like a grid that’s so close together you can’t see any space between the lines, and the whole gridpaper is just chock-full of stuff. The grid explodes and the space between the lines gets bigger and all the stuff spreads out.
That’s the universe at about 1 nanosecond. The big bang is that scenario, just reversed by 1 nanosecond and all the grid lines aren’t just super-close, they’re on top of each other. Things get really trippy and our understanding of physics breaks down before the first picosecond (10^−12). “Everywhere” used to all be at the same point.
