Critique 2: Research: Time (UPDATED)

 

TIME AS MEMORY

Accrding to, "McTaggart's most interesting observation however is that historical events have same time characteristic as made up stories. For example made up stories, as well as past historical events have in them, the earlier and the later as well as the past the present and the future, thus suggesting that past really is more like memory of events and does not exist any more than imagination of a writer. The above point becomes more clear when we compare past present and future to other recording devices like laser discs CDs and hard drives."

Present is the most real perception of time however almost all of what we perceive as the  present is already past. The present is a fleeting moment, whatever is happening now (present) is confined to an infinitesimally narrow point on the time line which is being encroached upon by what we think of as the past and the future.

PAST AND FUTURE ARE DURATIONS IN TIME

Unlike the present we see past and future as measurable
durations of seconds, hour, days, week months and years.

  A THOUGHT EXPERIMENT

Imagine two objects one moving in orbit around the other in space. Now suppose from our distant observation point of a fixed time we observe time to get slower in the area where these two objects are moving. We expect to see slower motion? We also should observe proportionally weaker gravitational force; otherwise the objects will get pulled together. If we observed faster time, we expect to see faster motion and stronger gravity to keep the objects from flying apart. While with zero time motion will freeze and gravity will become zero.

The increase or decrease in strength of gravity is only in relation to our fixed time from where we are making the observation. From the point of view (time) of the orbiting objects neither motion nor gravity has changed. As this thought experiment also can be extended to particles held together by electromagnetic forces we can say that time involves both motion and forces.

TIME CAN BE DEFINE AS

Time can be defined from many perspectives.  From perception view point time is an emergent concept which our mind creates. Present is the consciousness or awareness of recording of memory into the brain. Past is just a record while future does not exist. From point of view of physics time is presence of motion and forces in the universe.
