I wish I had a link, I think acollierastro talked about it briefly in one of her videos but I think it was a sidebar on something else so I have no idea which one. It was just one of those things where I heard the statement and it clicked on some weird intuitive level.

I probably used “chaotic” inaccurately, but entropy strives towards maximum disorder in that there is energy holding things together and that energy won’t hold forever. The big bang was basically a big explosion where a whole lot of order was imposed on the universe, for example by forming particles, and since then there’s this general trend towards things falling apart. Energy can be used to fuse a particle, but left alone that particle will eventually fall apart, even if it’s not moving. That’s entropy. So time is that quantity where, given enough of it, things fall apart.

Does that make sense? I have no idea if I’m explaining it properly, my physics background is super scattered.
