So how does theoretical physics "work" exactly? (hexbear.net)

To explain, I'm just a big old ignorant layman, but with other scientific fields I at least CONCEPTUALLY understand how they came to their findings.

Like if a Geologist tells me something about rocks I'm like: "Okay, idk how geology works, but I assume you did some kind of experiments involving rocks so you probably know what you're talking about."

Or if a neurologist tells me something about the human brain: "Okay, idk shit about neurology, but I assume you did some kind of brain scan or took some brain samples or did some kind of scientific experiment thingy to know this stuff about brains. I don't know the exact details but I can at least abstractly understand the process by which you learned this thing you're telling me now."

Then I'll see some news report about some finding a theoretical physicists made and it'll be like: "The Universe is made of strings! And also the sun is a black hole! The universe is shaped like a doughnut!"

And my honky ass is just like: "How the fuck do you know that shit? What are you looking at? How did you figure that crap out?"

It's mostly just math innit? Like, we notice that the arms of spiral galaxies are spinning faster than we would predict under the Standard Model's gravity math, so there must be some other thing happening. That's where you get dark matter.

Or we notice that the universe is expanding faster than the Standard Model's cosmic inflation math would predict, so there must be some other thing that's making it faster. That's where you get dark energy.

But it's all just math.
