Time




No Time !

The usual excuse for anything.

What is time ?

The famous definition of time is "...is what keeps everything from happening at once"

Well, I don't know what that means !

The basic unit of time is a second.

What is a second ?

A second as been defined to be the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.

Well, again, I don't get it.

I think that is the problem with time !

IT is too complicated to define & there are many theories about time.

If you think the stuff above was not complicated, get a load at these jargon :-

- Arrow of time( Time appears to have a direction – the past lies behind, fixed and immutable, while the future lies ahead and is not necessarily fixed)
- Chronon (a proposed quantum of time, that is, a discrete and indivisible "unit" of time as part of a theory that proposes that time is not continuous.)

As a layman, this stuff really is COMPLICATED !

But what I do know is that :-

1) When you are doing something fun, exciting & entertaining,
you don't know how much time has passed !

2) When you are doing something boring or waiting for something to
happen, it takes like forever !!!!!!!!!!

3) When you need time the most, it is not there &
when you no need time the most, it is there !

It's just weird !

Some people think time travel is more weird & impossible.

But, I think otherwise ! I rather say, " WHY NOT ?! "

The physics is complicated & extremely theoretical & full of paradoxes.

One paradox I find intriguing and not too complicated is the Grandfather paradox.

What is it ?

Is sounds something like this :-

Suppose a man travelled back in time and killed his biological grandfather before the latter met the traveller's grandmother. As a result, one of the traveller's parents (and by extension the traveller himself) would never have been conceived.

Complicated ?

Let me try breaking it down again :-

You go back in time and kill your grandfather. That means no father and no you !

Does it really exist ?

I personally don't think so.

There is a theory which is known as Parallel universes.

Imagine 2 parallel lines, you are in line 1.

When you go back in time , you are in line 2, so even if you kill your grandpa,
you will still EXIST as you are from line 1 !

This paradox can be seen in the Terminator movie series.



I'll be back !


The machines send a terminator back in time to kill John Connor's mother so that
John Connor will not be born.

John Connor still exist in Line 1 aka the future when the machines send a terminator to Line 2.

So, he sends another terminator to protect his mom.

In the movie, the setting is in line 2 aka the present & the action starts !

That is only in movies I guess !

For now, just focus on the task ahead & stop wasting time !!!!!!!!!

Time & tide wait for no man !
