Horizon BBC2 - What's The Time.....
Interesting program tonight (although Horizon is still a shadow of its former self).
The discussion was 'time' and exactly what it is.
I'm still baffled. I'm sure I'm wrong, but time, as a concept, seems to me to a human construct.
In the program they were explaining how gravity has an effect on time, that atomic clocks can vary, one to another, according to their proximity to massive objects.
But surely what is being affected isn't time, but what we choose to measure or represent time. i.e. what is being observed is the effect of gravity on atomic clocks.
Can anyone help me out on this?
