Gravitationally Lensed Galaxy
... Observations of star positions during a solar eclipse in 1919 proved this theory correct. Stars near the darkened Sun behaved exactly as Einstein predicted; the Sun’s gravity bent their light, causing an apparent shift in their positions. In 1937, astronomer Fritz Zwicky applied Einstein’s theory on ...
