Time is absolute and real

Metaphysically, time is distinguished as absolute and real.

Absolute time is continuous and is unaffected by the speed or slowness of

material things. Time is astronomically and mathematically calculated in

relation to the speed, change and life of a particular object. Factually,

however, time has nothing to do with the relativities of things; rather,

everything is shaped and calculated in terms of the facility offered by

time. Time is the basic measurement of the activity of our senses, by

which we calculate past, present and future; but in factual calculation,

time has no beginning and no end.
