comment The scope of physics, as taught in modern times
I feel obliged to point out that the only reason you were taught those basic Physics 101 concepts in a physics class is because they are easy, intuitive examples to which you can apply the simplest differential equations. Unfortunately students are never told this, and many like you come away thinking advanced physics will be similar to introductory courses. The reality is those topics are a holding pattern while your math education catches up, giving you at best just a glimpse of some important physical principles.

comment Why would a modern smartphone not work if the theory of general relativity hadn't been discoverd?
If GPS didn't work, you're right we would just develop something that did. But even without an understanding of GR, GPS would work just as well as it does today. See this answer for why the necessity of GR is a myth.

comment How does the inclusion of vacuum energy modify Newtonian gravity equation of motion?
@Javier I've actually half written an answer to that effect. It's tricky, though, because in fact no experiment, neither local nor global, could locate $r = 0$, since with this particular potential the acceleration pushing any two points apart is exactly proportional to their separation. That is, Newton+metric expansion is self-consistent, it's just the more subtle issue of Newton+nonzero homogeneous gravity source that falls apart on consistency.

@Elnur What you suggested isn't wrong, but it's actually equivalent to what is already there ;)
