Time is just another name for change.

Definition of a second.

One second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine energy levels of the ground state of the cesium-133 atom.

If you need to understand the world. You need to understand the change. Time is just another word for change. I posted this online and received with variable responses from the philosophical community. Some argued it is not. Some agreed it is giving evidence. After all It appears only one group of these individuals is correct by default. Unless we are living in a quantum universe where both of them be correct with a variable probability. If we exclude that as an answer, there are ample evidence for me to say time is just another word for change. And roots of this idea, actually extend both into western and eastern philosophy.

Time and change - historical references

Aristotle

“Time is the number of motion with respect to before and after.”

(Physics, Book IV)

Buddha

The first noble truth is, Annichcha, which is another name for change or impermanence.

Buddha taught:

• All conditioned things arise and pass away.

• Nothing stays fixed — bodies, feelings, thoughts, even identities.

  
  

Instead of asking “What is time?”, Buddhism asks:

What happens when we see that everything changes?

You do not have to go somewhere to see the evidence of time is just a change. Every time we talk about time, we have to talk about a change of something. From the time you sleep to the time you wake up, you know time exist only when you realize there have been changes. If the sun did not rise in the morning (change), and if you did not feel hunger (change), if the rivers did not flow (change) butterflies flap their wings (change) or the earth did not rotate (change) Your body did not decay (change) and you did not have ability to move (change) and the consciousness remained like a rock, with the same thought into the eternity (change). If all that happened there would be no way we can say time exist. It is merely a feeling in one's consciousness which arise due to Side effect of observed change in the environment, or in the state of mind.

In the one second definition above agreed by scientists, is just another "Change" which happens in the environment. But, when we adhere to these objective definitions, frequent question which comes to my mind is what if? What if the universe is within another universe and this outer universe somehow caused our universe to expand. If so, everything in our universe would expand, including all the observations. So, called objective time would change, but ever not showing subjective evidence of it.

Eastern philosophical approach.

Somehow, I like the eastern philosophical approach to the time. Once we have enough understanding, time is not what we see on the clock, but some feeling due to observed change. "Change" becomes fundamental "thing" to be observed in the universe. If "change" is the fundamental nature of the universe, the life, becomes part of this. I can see where this leads to. If life is fundamentally change, the permanent happiness, the success, the peace that we are seeking needs a second consideration. Are we going to achieve anything? I am not here to shatter your dreams of future and to push you into nihilistic absurdism. But, if you learned the lesson, just observing the change in the nature might teach you something, that only wise people might be able to see. Let's be vigilant, and observe how,

A raindrop becomes ice crystal in the winter

A leaf changes its color in the Autum

Kids grow into adults

Adults end up in graveyards

Perfectly healthy cells become cancerous

Global temperature rises

Days become nights again and again

Parties end

Rich becomes poor and poor becomes rich.

Winners become losers

Status of mind changes throughout the day.

The real question is can you look at the change in a non-judgmental way? A thing that is neither good nor bad?
