Gravitational Lensing.

On 8 April 2024, a slice across North America will be treated to the rare and wondrous sight of a total solar eclipse. Total eclipses are awe-inspiring to experience, as the Sun is completely blotted out by a perfectly positioned Moon, turning day temporarily into night. Millions of people are eagerly awaiting this eclipse, but from a scientific perspective, it’s unlikely it will come anywhere near the paradigm-shattering impact of the eclipse of 6 November 1919.
