Exactly my thinking. We observe the effects, or the time pulses, from our perspective, which is in turn relative.
A rough analogy would be to compare the main 3 different temperature scales: where Celsius and Fahrenheit are relative to common things on our planet (water freezing point for Celsius, and brine for Fahrenheit), as opposed to Kelvin, where "
absolute zero, the temperature at which all thermal motion ceases in the classical description of
thermodynamics." (wiki).
While we have watches, we still don't have an "absolute zero" measuring system for time. And we may never have. For those who haven't viewed the youtube video I posted earlier, time has finally been determined to exist before the big bang.
The big problem is, all this is speculation based on clever thinking and mathematics. No tangible hard evidence exists for us, mere by-products of the vibration of strings. You know those delicious BBQ ribs and that ice cold beer you just had for lunch? They never existed, they were just string vibrations, and so are you
