2. A Test for Einstein’s General Relativity
The total solar eclipse of May 29, 1919, provided a unique opportunity to test Albert Einstein’s theory of general relativity. Einstein predicted that massive objects like the Sun would cause a curvature in space-time, bending the path of light passing near them. This effect was expected to be measurable during the eclipse, as the Sun’s light would be obscured, allowing astronomers to observe the deflection of starlight. In contrast, Newtonian gravity predicted a smaller deflection, making the eclipse a natural laboratory to compare the two theories. (scientificamerican.com)
