In an earlier post I mentioned that I believe that time is perceived differently by people of different ages. So here is my reasoning.
According to Einstein’s theory of Special Relativity time is not absolute – it can vary according to the speed of an object. The theory pertains only to the time relationships between two objects where one is moving away from the other at a fixed speed.
To simplify the theory let me give an example:
A rocket B
A is a base station that shoots a burst of light to station B every two minutes.
There is a rocket ship traveling between A and B at ¾ the speed of light.
Every time the rocket receives the burst of light from A it fires an identical burst of light to B.
Because the speed of light is constant B receives both beams of light from A and the rocket simultaneously at two minute intervals.
But, because the rocket is moving away from A at ¾ the speed of light (constantly increasing its distance from A) it is receiving the light flashes from A, not at two minute intervals, but at three minute intervals.
Ref: Einstein’s formula – for geeks…
Elapse time = the square root of the time in reference-one divided by one, minus the speed of the rocket square divided by the speed of light square.
The crux of this is that A is transmitting light burst at two minute intervals - and B receives the light from station A and the rocket at identical two minute intervals; where as the rocket is receiving and transmitting its light burst at three minute intervals.
Time is moving faster on the ground than it is on the rocket ship. What takes two minutes to happen on the ground takes three minutes to happen on the ship.
By the way, this has been proven in experiments.
Einstein’s General Theory of Relativity deals with time variations due to strong gravitational fields.
But we don’t have to go into that - it is enough to know that time is not constant but can seem to vary under different circumstances. (Actually the cosmos doesn’t give a damn about time and gravity and space – these concepts only matter to humans as we try to understand and catalog everything to our limited understanding.)
Now for the Ol’Buzzard’s Theory of Relative Time:
A child of ten perceives a year as one tenth of his life. It seems forever between one Christmas and another, or birthdays.
A man of seventy perceives a year as one-seventieth of his existence – a relatively short time between birthdays.
Time is experienced seven times faster for a seventy year old than for a ten year old.
Each year I seem to get older faster. That’s my story and I’m sticking to it.
