Does time and tide wait for none ?

"Time and Tide wait for none" is an oft-repeated adage. I am not quite sure whether it is an adage or a proverb. To avoid an unwarranted controversy, let us call it a proverbial adage. We know very little about this adage, except that we repeat it like a parrot, of course,with some difference and the difference really matters in real life.


We know neither time nor tide very well to give such generalizations. Time as we know is only by its measurement, that is by the clock we hang in our homes. That time waits for the replacement of battery or winding of the spring when its potential energy drops. But deeper understanding of time still remains a challenge for the science community. Time by the clock has no relation to Time which goes with Tide.


The proverbial adage gives a feeling that time and tide are independent and does not wait for either and neither waits for any other. can that be true?


Can tide be independent of time? It can only be independent of time shown in the clock(tide will happen even if there is no cell in the clock). But tide cannot happen without time which is independent relatively to tide. Tide cannot be independent of time and has to wait for the latter, be it a low tide or a high tide.


Moving on, time is a very difficult concept to crack. However we do know that tide is dependent on the gravity of the moon and earth. What is interesting here is the relation between time and gravity.


Time can be thought as analogous to motion of earth. Like time, motion of earth is unidirectional,continuous and eternal. In fact one can argue that time is only a measurement of motion (At this point, i believe so). The units of both merge at some level (higher or lower?)


So tide cannot happen without time and time without motion. which is first is a futile argument for now. Assuming that motion is a "relatively" independent variable, rest of the parameters depend on it. Now moving from relativity to relative independence, what is this motion all about and what causes this motion. Its the gravity of the sun, moon, other planets and probably other galaxies. But so far as the tide is concerned, it is also caused by gravity of the moon. But that in turn is dependent on the relative position of the earth with respect to moon. So tide is dependent on earth i.e. motion i.e. time and that is dependent on sun,earth,other planets, other stars, our galaxy and probably other galaxies.


It is however an altogether different question whether it was moon or earth first? water or motion first? gravity or motion first? These are as simple as asking whether it was egg or chicken first?
