I'm already aware of time dilation, from the measurement of time by a scientist on the summit of Mount Everest @ 29,000 ft with an identical time clock, and someone at the base of the mountain with exactly the same type of clock. The cesium clock airliner experiment I referred to in my comments was really done. Another example of time dilation.noting that dilation of time speeds up as you go higher and faster, this is due to the reduced effects of the earth's gravitational force as you move further way from the ground and Earth.That is why if you go to Mars and stay for some quantifiable period of time, when you return to Earth, you will have not aged as much as the people on Earth that you left behind. Yes, time is relative, I never said it was not, Our Earth time is base on our Sun. Look at my comments again, I said and I quote," In our Sol system, time measures our hours, days, weeks and years. It is quantifiable like light, but more ethereal in its true substance",Einstein proved its fundamental relativity." As far as the Philosophical view of what time is as being empirical. I spoke of a Philosopher's viewpoint NOT MINE, I also quoted, "Philosophy may lament on what time is, and unable empirically to prove it is without scientific proof! I was merely saying that a Philosopher cannot define time in an empirical way without scientific proof via, observation , investigation , experimentation, data collection, and analysis. (It is called the Scientific Method ) No, I did not say that time was empirical. Furthermore, I was referring to the probe sent by NASA to confirm Einstein's theory about the relativity of the the Space-Time continuum. The very definition of empirical is: Empirical evidence, also known as sense experience, is a collective term for the knowledge or source of knowledge acquired by means of the senses(That is Philosophy!observation by the senses!).
You go on to say that time is empirical and as you say "we make that up as we go", You also said that "Because of the fact of us not having an original origin to measure from" What is an original origin ??? are you saying that time has no origin ???, no beginning, That is far from the truth, were you born??? do you exist???, if you do, did you have an origin of time from the beginning of your life???. Do you work??? do you punch a time clock???? Unless you can go to work when you want, and leave if you feel like it, Time does have an origin,It has a beginning!! A stop watch at the Olympics for the 100 yard dash has an origin. Usain Bolt would not be the fastest man on Earth without a time zero starting point!!!. Usain Bolt had to push off of the starting blocks at the Olympic track. The origin of time is and will always be the rising and the setting of our Sun, SOL in our solar system, we do not determine time, the Earth revolving around on its axis every 24 hours does. Every year it takes 365 days based on our solar system, to orbit around our Sun. We are merely a satellite. Man-made satellites are equipped with tiny orbital rocket thrusters to correct their orbit whether it is a Geo-synchronous, or a stationary orbit. Variations in gravitation forces and orbit decay and variations in centripetal force!.
The two concepts of definition about Philosophical perception of time and Scientific evidence and definition of time are incongruant and should not be discussed in the same context. As far as acceleration goes, acceleration is defined by the average change in velocity divided by the average change in time: each variable in the equation has an origin or zero starting point , starting velocity, starting time, else if one of these variable quantities v or t was without an origin the formula would not be true. To have acceleration you start accelerating from V=0, and T =0. Otherwise,there would not be any acceleration! You would be at some constant velocity with no beginning and no end. That simply does not exist in this Universe!We do not! as you say make it up as we go!!
