Spend a trillion dollars building a bigger supercolider if you want more fundamentals. I think the application of these discoveries is much more important at this point. What do we actually use GR for? Corrections to gps, and ... it's not like it's gonna cure cancer. Technology will do that. We've exhausted all the fundamentals that we can access, that's what's happened. You want more fundamentals, you need more access. You want more access, Get ready to ride the exponential curve of costs
That is pretty contentious even in physics circles (from what I've heard in videos). The build me a bigger particle collider might not have any impact. We might not see any of the hypothetically proposed stuff.
