Cause and effect was the starting point for Einstein's theory of special relativity. Most of what he is known for results from that paper.

In short:
In 1887 the Michelson–Morley experiment showed that the speed of light was always measured to be the same even when planetary motions should have created a detectable difference due to motions.

In 1905 Einstein wrote his paper which argued that the speed of light always had to be constant or there could be instances where one light beam could outrun another and you would get the information about an effect before the information from the cause. His whole theory was dependent upon causality.

Mathematically he took some classic equations by Maxwell, Faraday, and Newton and showed that when they pertained to light, and the speed couldn't change, then the value for time would have to change.

What followed was a bunch of scientists saying this must be nonsense and they pointed out various strange things would happen if time was not a constant. Later experiments showed that those strange things were indeed happening and cause-effect was the guiding principal that determines our universe. It's the strange things which have mostly been popularized.
