simultaisuutta
Simultaneity refers to the concept of events happening at the exact same time. In classical physics, simultaneity is considered absolute, meaning that if two events are simultaneous for one observer, they are simultaneous for all observers, regardless of their motion. This understanding is intuitive and aligns with everyday experience.
However, Albert Einstein's theory of special relativity revolutionized the understanding of simultaneity. Special relativity postulates that
The concept of simultaneity has profound implications in physics, particularly in understanding spacetime. In the framework
