SUMMARY
The scientific definition of time is primarily based on atomic clocks, specifically the International Atomic Time (TAI), which averages the time from over 200 atomic clocks worldwide. The SI second is defined in terms of cesium atomic clocks, emphasizing the influence of relativity on time measurement. Discussions highlight that time, while measured through duration, remains an indefinable property, as it cannot be empirically tested. The relationship between time and change is crucial, as time is perceived to exist only in the context of change, making it a complex and often debated concept in physics.
PREREQUISITES
- Understanding of atomic time standards, specifically TAI and SI second definitions.
- Familiarity with the principles of relativity and its impact on time measurement.
- Knowledge of the difference between duration and time in physics.
- Basic concepts of quantum mechanics, including the Copenhagen and Many Worlds interpretations.
NEXT STEPS
- Research the principles of relativity and their implications on time measurement.
