To present a new scientific idea, particularly a flaw in General Relativity, one must first establish credibility in the physics community, typically by obtaining a PhD. Writing a paper is essential, but it must be submitted to a peer-reviewed journal to gain recognition and undergo scrutiny. Familiarity with existing literature is crucial, as many claims of flaws are often based on misunderstandings of the theory. The process involves significant risk to one's credibility, and it's important to be prepared for both criticism and defense of one's ideas. Ultimately, a deep understanding of the subject matter is necessary to navigate the complexities of scientific discourse.
