The nature of time

Post by brian livesey »

Did Anyone listen to the Radio4 programme yesterday evening, chaired by Brian Cox, about Time? From a layperson's point of view, none of the participants seemed to have resolved the question of what time is, or whether it exists, unless we missed something.
As for the question of whether "absolute time" exists, this was answered some years ago by the noted Dutch astrophysicist, Anton Pannekoek, when he said that we only need to compare clocks: all clocks are different.
As Pannekoek also said, time exists as a mental construct for monitoring change and as a necessary survival stratagem for making predictions. Being an intangible doesn't deny time's existence. Thoughts and feelings are also intangible mental constructs but are no less real for that - as thoughts and feelings.
