Question
What was Einstein’s Special Theory of Relativity?
✓
Answer
One of the famous papers of $1905$ was Einstein's Special Theory of Relativity, according to which time and distance are not absolute.
For example two perfectly accurate clocks would not continue to show the same time if they came together again after a journey if one of them has been moving very fast relative to the other.
From this came the world’s most famous formula which described the relationship between mass and energy: $\mathrm{E}=\mathrm{mc}^2$ where E stands for energy, m for mass and c for the speed of the light in a vacuum (about 300,000 km/s).
