1919 Solar Eclipse and General Relativity

The video explains how a total solar eclipse allows stars to be seen during the day and how this phenomenon was used to test Einstein's theory of general relativity. It contrasts Newton's and Einstein's views on gravity, highlighting Einstein's idea that massive objects curve space. The video details Arthur Eddington's 1919 experiment during a solar eclipse, which confirmed Einstein's predictions and revolutionized our understanding of gravity. This experiment made Einstein a global celebrity and paved the way for future discoveries, including black holes.

What is the only way to see stars during the day?

• Through a telescope

• During a total solar eclipse
