The 1919 Solar Eclipse: A Fateful Moment for the Universe

The discovery of the 1919 solar eclipse had a profound impact on our understanding of the universe, changing the history of science forever.



During the total solar eclipse of May 29, 1919, the Sun's light was blocked, allowing scientists to observe stars near the edge of the Sun with telescopes. (Photo: Thanh Nien Viet)

Sir Arthur Eddington led two expeditions to the islands of Príncipe (Equatorial Guinea) and Sobral (Brazil) to photograph the positions of the stars at the moment of the solar eclipse. (Photo: Privatdozent)

His goal was to measure whether light from stars is deflected when passing through the Sun's strong gravitational field, as predicted by Albert Einstein's General Theory of Relativity. (Photo: Live Science)

After analyzing a series of photographs, Eddington confirmed that light was indeed bent with the exact deviation as Einstein's formula. (Photo: Wikipedia)

This discovery is the first experimental evidence that space-time can be curved and that gravity is a result of this phenomenon. (Photo: Discover Magazine)

Shocking information worldwide, The Times (UK) newspaper published a big headline: "Revolution in science: New theory of the Universe confirmed". (Photo: Smithsonian Magazine)

The experiment not only made Einstein famous worldwide, but also affirmed that science could transcend national boundaries in the divisive post-war period. (Photo: Space)

The 1919 event laid the foundation for a series of later achievements such as the Big Bang theory, the discovery of gravitational waves, and GPS positioning based on the very time effect that Einstein described. (Photo: EarthSky)
