I want to know the answer to the following question:
What did general relativity do that made it tentatively acceptable when it was proposed?
All the background I'm provided with is that "Gray does not, however, give any indication of what available evidence these theories were at odds with, and his appeal to "crucial support" illustrates the very inductivist approach to science that Popper sought to show was logically illegitimate.". Is that enough to answer the question?
Answer: no
