How Einstein Thought of the Theory of Relativity
Beeyond Ideas・2 minutes read
Albert Einstein's groundbreaking theories of general and special relativity, inspired by Sir Isaac Newton's work, explained gravity, space-time curvature, and gravitational lensing, while also addressing questions Newton couldn't answer, like gravitational time dilation proven by experiments like Eddington's gravitational lensing test.
Insights
- Albert Einstein's groundbreaking theory of general relativity, published in 1915, addressed questions about gravity that Sir Isaac Newton's laws couldn't answer, revolutionizing our understanding of the universe.
- Einstein's thought experiments, such as envisioning light bending due to gravity, led to the development of concepts like space-time curvature and gravitational lensing, demonstrating the interconnectedness of light, gravity, and the fabric of the cosmos.

Einstein's Theories: Light, Gravity, and Time
- In 1895, Albert Einstein, a 16-year-old boy, envisioned chasing a beam of light, leading to his groundbreaking theory of relativity.
- Sir Isaac Newton, in 1687, published "Mathematical Principles of Natural Philosophy," outlining his laws of motion and gravity, which inspired Einstein's work.
- Einstein's theory of general relativity, published in 1915, explained gravity and its source, addressing questions Newton couldn't answer.
- Einstein's theory of special relativity, from 1905, focused on the speed of light and motion, later unified with gravity through the equivalence principle.
- Einstein's thought experiments, like imagining light bending in space due to gravity, led to the concept of space-time curvature and gravitational lensing.
- Gravitational time dilation, a key aspect of Einstein's theories, explains how time slows down near massive objects, as proven by experiments like Eddington's gravitational lensing test.
