Albert Einstein: The Revolution of Relativity

In 1905, Einstein’s special relativity showed that space and time are linked into spacetime.
He revealed that the speed of light is constant for all observers, no matter their motion.
The famous equation E = mc² connected mass and energy as interchangeable.
Special relativity explained why time slows down and lengths contract at high speeds.
In 1915, Einstein introduced general relativity, a new theory of gravity.
He described gravity not as a force, but as the curvature of spacetime by mass.
General relativity predicted phenomena like black holes and the bending of light by stars.
Einstein’s theory was confirmed in 1919 when starlight bent around the Sun during an eclipse.
Relativity reshaped cosmology, leading to ideas of an expanding universe and the Big Bang.
Today, relativity underpins GPS, space travel, and our understanding of the cosmos.
