3 Critical Things about Time Travelling
Causal Loops3 Critical Things about Time Travelling

But,some people out there who take their movies seriously can even find some element of logic in time travel.
I am sure almost everyone can.
For those of you who don't know what it is,here is a quick run down.
What is time travel?
Time travel is a concept of movement ,usually by humans, between different points in time.
Time Travel can be seen in many movies such as in Harry Potter and also in comics where the concept is that if you run fast enough then you can open up a portal connecting both past and future with your present hence,enabling you to travel through time.
Yup!seems logical I guess.
Along the years many Superheroes have travelled through time and it's just like a normal thing for the fans.But,there are some critical things relating to such time travel that we should keep an eye on.
1)Timeline Remnant
For those of you who didn't quite understood it or who don't know what it is,there are many common questions like,
Is it just that you travel back in time to your previous self and then you have two images of yourself?
Flash was seen to sacrifice one of himself but still lived as nothing happened,how?
How can you just take one whole Flash from the speed force and have it die?
Wouldn't kill yourself from the past also mean killing you?
In order to explain it, we have to know that only speedsters can have time remnants which are protected in speed force.
So,when Flash says that he went in the past,it actually means that he went to his past self,and then there were two Flash at that particular moment.
He then convinced his past self to not travel back in the past again.Thereby having changed his other self's future considerably because now the time loop won't keep repeating.Hence even if he was to die,the Flash existence would not seem to vanish however,the one dying would not just be a copy but an actual Flash having the same past but sadly no future considering how he would be dead.
That is why it must be difficult to convince yourself to just die for the good of his other self.But.Flash does it to save the World.
But,how would this effect the Time Continuum is still not explained.
How Reverse Flash Came back?
The concept is that you can make time remnants of both past and future but in case you die such as reverse Flash then Speed force would keep your copy intact but that would be relating to your life's past and not the chronological past.
For those of you who don't know, chronological past is the past that we normally know such as every date before this one now.But,your life's past can be different.
Wondering how?
The answer is simple.You can travel in time.What if you were to travel in past now and die there.Your date of death would be somewhere before now but,that would still be the future you have to this date.
So,the date you are living in now is your life's past and when you die,your date in the past would be your life's future.
To explain how Reverse Flash came back,consider his life.
1)Born in future
2)Travels to where FLASH is for the first time to know the time period.(back in time)
3)Comes back in future.
4)Gets stranded in past when trying to kill The Flash when he was little but ends up killing his mother and then eventually dies himself.(again travels to the past and dies in the past)
Now,if he were to die at Step 4,then time remnant that would be in speed force would still come in Step 2 as it is his life's past.Time remnant would be in his life's past where he sees Dr. Wells from Earth 2 and knows whom to kill in Step 4.The cycle has to repeat, therefore,Speed force keeps time remnants.
Note that dying in future does not stop the time cycle.It just marks your death there at that particular point.If the previous cycle had already begun,there is no stopping it because speed force itself would preserve it.
2)Closed Loops
The most important thing regarding time period is the closed loops.That means that if a person was to travel in time then he must return back at the exact same time at the same position or else between these travelling and returning points his existence would vanish creating unimaginable results like erasing the world or being sucked into a singularity and ultimately destroying the Universe.
This fact is often neglected in movies and therefore,we should always watch out for it.
Another example of the complexity of Time Period is related to a simple question that is ''Can You really change past?''
Most of you may have already begun wondering about it.The complexity here is explained by an example below.
Let's say for the sake of argument,a person had just one son.But,he lost his son to a terrible accident.Now,the person devastated by this tragedy thinks of creating Time Machine.
He succeeds and travels back in time to save his baby.All is good, right?
Well, ask yourself this "If his baby would never die,then how come he would think about inventing time travel?"
This will indeed not only destroy his future but would also affect time loop in a very bad way as one can expect because the cycles won't matches any details with one another.
Time Travel is not simple.
3)Memories
Well, he shouldn't be confused because,his memories should come to him because, after all,he did live his life and didn't just looped through it.
Even if he had to go in the past and change it,his life still continues in the new future as well.
Same with Flash in the second season when he came back from past while being chased by Time Wraith,he was shocked to see Hartley Rathaway on their side while he should have just had his memories leading up to these events.
These memories should also overload their brains with too much information at some time making Time Travel not only complex but extremely dangerous.
The Butterfly Effect should be an inspiration to them.
But if time travel was easy then everyone would do it,right?
Have any more questions about it then ask away.
Hope you found it useful and won't forget to like and share.
