We make models that say things work like this (some metaphor we can use our senses for)
Then we apply these models to things we CANNOT sense directly. But indirectly we measure and tinker and come up with a new model, like for EM waves. Then we put math to it. We do this over and over and over in science. So now we maybe get down to the level of the small and we invent the field model because it seems to help us fit math with it. Then an observation is made that does not fit this model is made and we change the model and then... all these brand new questions arise, they just explode with the new observations. So many new models have to be made. So we make more models. But the models for the way the Higgs field works but it contradicts the model for gravitational, electric and magnetic fields. But it works, so we go merrily along because it can make predictions. Then a new phenomena is observed that does not fit what the model predicts.
Do you really think this is going to come to an end? That there is an equation or model for everything? Really? You think science is that mighty to take on every aspect of thoughts? If anything I could argue it is getting more tedious by exploding into thousands of new questions that lead down a brand new path that is one of many paths.
But it does work most of the time in predicting and making our lives different (some would argue much more comfortable). So science rules. Yes it is fantastic stuff. But as far as answering everything... no fckn way. I would agree that merely making things up seems silly. But then it kind slaps one in the face when you see how science is very limited in finding some very fundamental rules that need answers. The math we rely on may even be massively flawed. (Read K. Goedel)
I can give you some podcasts of some of the best physicists, that I cannot possibly keep up with the math, but who basically see what I have written above. Do you want them.
https://lexfridman.com/podcast/
I suggest starting with the podcast with Harry Cliff. Then keep going.
Fridman sounds like a goofball, but he asks everyman type questions to very smart people, and some not so smart
I would stick with the physics guys. When you listen to one, give me a heads up. Maybe you will get what I wrote above.
