Research in physics today is predominantly collaborative, with many physicists emphasizing the importance of teamwork due to the complexity and breadth of knowledge required. While it is theoretically possible for an individual to conduct research alone, the likelihood of significant breakthroughs is low, often leading to isolation or being labeled as a "crackpot." Historical figures like Einstein, often viewed as lone geniuses, actually relied heavily on collaboration and discussions with peers. The expansion of knowledge and the costs associated with research further necessitate collaboration in modern physics. Ultimately, while individual contributions are still possible, they typically occur within a broader context of interaction and shared knowledge.
