Time & Change June 10, 2007
Posted by Rastaban in : Cosmological , 2 commentsTime is a function of change — if there were no change there would be and could be no time. Time in fact is only a way of measuring change by comparing it to a standard clock (a standard clock is something which changes in an extremely regular way). Since time is the result of a comparison of change to a standard clock, time can only exist if (1) a standard clock exists, (2) a change to be compared to the clock exists, and (3) a being capable of doing the comparison exists. This is a matter of logical necessity from the definition of time.
It follows that time only comes into existence once all three conditions are met. The most limiting condition is the 3rd, the existence of a being capable of doing the comparison, and I say this because 1 and 2 are known to come into existence billions of years before 3 comes into existence.
When Stephen Hawking and other cosmologists talk about time coming into existence with the big bang, they pretend that there is a scientist like them, a being capable of doing the comparison which creates time, right back there at the beginning of our universe looking on. That of course is a conceit. Since time is a comparison, it can only exist in a mind. Unless one is a theist (Hawking and most other cosmologists are not), one has to admit that time cannot exist until the evolution of organisms with minds capable of doing the right sort of comparison.
The scientific conceit is that we are right there at the big bang, looking on. (more…)
