Einstein did not use Minkowski spacetime in his original derivation of E=mc²; instead, he developed the equation based on his theory of special relativity in 1905. Minkowski later introduced the concept of spacetime in 1908, which provided a geometric interpretation of special relativity. The discussion clarifies that while Minkowski's work is crucial for understanding the implications of E=mc², it was not part of Einstein's initial formulation. This distinction is essential for comprehending the historical development of relativistic physics.
