Intelligence and knowledge are not determined by a person's ethnicity or the socioeconomic status of their community. Therefore, it would be incorrect and unfair to make assumptions about any racial or ethnic group's understanding of scientific theories, including Einstein's theory of relativity.
Access to education and opportunities for learning can vary among different communities, and socio-economic factors can play a role in determining the educational resources available to individuals. However, it is essential to recognize that intelligence and knowledge are not limited to specific racial or ethnic groups. People from all backgrounds have the capacity to learn and understand complex scientific concepts, given the opportunity and resources to do so.
It's important to avoid making generalizations or stereotypes based on race or socioeconomic status. Individuals' knowledge and understanding of Einstein's theory or any other scientific concept can vary greatly and depend on their personal interests, educational background, access to resources, and individual efforts to learn.
