There were several scientists who contributed to refining and expanding upon Albert Einstein's theories, but it would be inaccurate to say that any one person "corrected" Einstein. Einstein's theories, such as the theory of relativity, have undergone further developments and refinements through the work of subsequent physicists and researchers.
One notable physicist who made significant contributions to the field of physics and built upon Einstein's work was Niels Bohr. Bohr was a key figure in the development of quantum mechanics and made important contributions to our understanding of atomic structure and the behavior of subatomic particles. However, it is important to note that Bohr's work did not "correct" Einstein's theories but rather provided additional insights into the nature of the physical world.
Science is an ongoing process, and theories are constantly refined and expanded upon as new discoveries are made. Einstein's work laid the foundation for modern physics, and subsequent scientists have built upon his ideas to deepen our understanding of the universe.
