A major new idea, one which overturns an existing, well-supported theory, does not get established in one paper. There has to be follow up and debate, and if the idea holds up to scrutiny it will be accepted.
Beware the underdog narrative in science journalism. This narrative severely misrepresents how science really works. It's designed to elicit our sympathy for a not-yet-established theory, maybe one that is socially attractive, and to arouse our indignation against the staid community of eggheaded scientists. This underdog narrative plays on our emotions, it makes for a good read, and helps us feel good about ourselves when we stand up for our convictions.
What gets lost is the scientific method, the idea that novel proposals need to be thoroughly vetted and tested, no matter how intuitively attractive they are. That vetting process is done by a dynamic community of smart, educated, competitive people, who care passionately about science. It's a community where everyone wants to come up with the next big theory that overturns long-held beliefs. But that's hard to do, especially in fields where all the low-hanging fruit has been picked over by really talented people for decades or centuries. If a new theory is being presented in the media as the centerpiece of an underdog narrative, you can bet the farm that this theory is not yet sufficiently substantiated by the evidence. That doesn't mean it's wrong necessarily, but it does mean that the hypothesis has not yet met the rigorous standards of evidence that have served science well for centuries.
