Atheismo said:What does QM have to say on the ontology of time?
Is time absolute or relative?
What does quantum entanglement have to say on the subject?
Absolute time refers to the exact measurement of time using a specific reference point, such as the atomic clock. Relative time, on the other hand, is the measurement of time based on the perception of an observer or a comparison to another event.
Absolute time is considered to be more accurate because it is based on a precise and constant reference point. Relative time can be affected by factors such as the speed of an observer or gravitational forces, making it less precise.
No, absolute time and relative time cannot be used interchangeably. They are two different concepts and have their own advantages and limitations. However, they can be converted into each other using mathematical equations.
Time dilation, a phenomenon described by Einstein's theory of relativity, states that time can appear to run slower or faster depending on the relative speed and gravitational forces between two objects. This can affect both absolute and relative time, making them appear to be different for observers in different frames of reference.
Relative time is more commonly used in everyday life as it is based on our own perception of time and is more relatable to our daily experiences. However, absolute time is still used in certain fields such as science, technology, and navigation due to its precision and accuracy.
