Frankly, the world as we know it is going away, soon.

273. Sorry, no such thing as time travel

Why is that?
Because Time is a human-made system to measure Change.

Time cannot be measured without constants.
We based our time systems on the rise & fall of the Sun on Earth's horizon and the rise & fall of the Moon on Earth's horizon.

Either Solar or Lunar calendars we made since the Sun & Moon come up in consistent patterns that can be tracked & measured.

The only way to go back in time is to rewind the clock backwards.
There! You just went back in time!

There is only Change which goes on its own accord.
That's why some 40 year olds look like 25 year olds & some 40 year olds look like 55 year olds.
It's because their biological changes run on their own accord.
Some are baby faced while some are haggard.

That's why some people get gray hair when they're young.
We associate gray hair with aging because we seen the constant of gray hair emerging when people age.
But gray hair is not always necessarily a marker of age.
And some older folks have NO gray hair.

This wish to go back in time comes from human regret.
Because hindsight is 20/20 we wish we could go back do things differently to affect how we are in the now-time.
We regret losing our youth, we regret causing harm to another, we regret missing opportunities, we regret the deaths of our loved ones & wish we can go back to fix the past for the benefit of ourselves in the present.

That show Quantum Leap (one of my favorites) always said "To set right what once went wrong".
I love the sentiment myself. But it will always remain Science Fiction.

The Past is just Now with a different arrangement of the elements.
A different patchwork of changes.
You can always talk with older speaking patterns & idioms, use older technology, dress in older fashions.
But you will always be in the Now.

Time is just a measurement of Change.
And the only TRUE constant IS Change.
