First, let’s talk about fixed points in time. These are specific moments in time that cannot be changed, no matter what someone does in the past or future. An example of a fixed point in time might be the birth of a superhero.

Whenever someone travels back in time and changes something, they create an alternate reality. This alternate reality can operate independently of their own. So when Barry Allen travels back in time, he creates an alternate reality, leaving his original timeline intact.

Journeying through time in the Speed Force

Barry Allen has the power to travel through time with the help of the Speed Force. However, each time he does so, he risks serious side effects, including injuring himself or changing his own timeline.

Time Traveler’s Dilemma

The time traveler’s dilemma is a paradox where time travelers feel like they can change events to benefit themselves, but any alteration has the potential to create dangerous unintended consequences. The most famous instance of this is the butterfly effect – a small change in the past results in significant changes to the future.

Creating Stable Timelines

To create a stable timeline, time travelers must ensure that all alterations to the past fit cohesively in the time period they are visiting. If the changes to the past do not fit well with the period, this can create a ripple effect that will damage the timeline of the present.

Barry’s Journey through Time

In The Flash movie, Barry travels back in time and inadvertently saves his mother’s life, thinking he has created a better life for himself. In doing so, he creates an alternate timeline that is drastically different from his original timeline.

Restoration of the Original Timeline

In restoring the original timeline, Barry had to let his mother die, undoing all of the changes in the alternate reality. During this reversal, the alternate timeline ceased to exist, and the original timeline went back to the way it was as if it had never changed.

The Differences Between Timelines

Whenever a timeline is changed, the world in which the characters exist will be different. In most cases, the differences are minor, but sometimes they can be so major that it causes significant changes in the present. This is known as the butterfly effect.

The Butterfly Effect of Changing Barry’s Past

In The Flash movie, Barry’s life is vastly different in the alternate timeline. He is no longer The Flash, his mother is alive, and the Justice League doesn’t exist. The butterfly effect displays the profound implications of even the smallest changes in time.

The Consequences of Time Travel

Traveling through time has dire consequences, and in some cases, it can ruin the very fabric of existence. This is because time is a fragile construct, and any alteration can lead to a chain of events that will change things for the worse.

The Reverse-Flash and Random Timeline Changes

Reverse-Flash is one of the most notorious villains in The Flash universe, and his obsession with time travel ultimately led to his undoing. His many attempts to alter the timeline caused random changes, rendering most of his efforts pointless when things went off the rails.

The Paradox of Predestination

Predestination is the idea that events will occur in a specific way, even if someone tries to change them, as those changes were always part of the plan. This paradox is especially relevant to time travel since if events are destined to occur that way, any changes someone makes will still end up leading things back to their intended outcome.

The Attempt to Change Barry’s Mother’s Fate

When Barry travels back in time to save his mother, he creates an alternate reality where it seems like he can create a better life for himself. However, when he doesn’t manage to save her, he learns that some things are inescapable and destined to occur.

The Importance of Time Travel Knowledge

Traveling through time is a complicated process, with many variables that can go wrong. That’s why it’s important for anyone planning to change the past to have a solid understanding of the impacts of time travel and the dangers it poses should they attempt to alter things.

Barry’s Learning Curve with Time Travel

Throughout The Flash movie, Barry learns the importance of understanding the consequences of his actions when he travels through time. He also learns that changing events in the past always leads to unintended consequences and irreversible damage.


In conclusion, time travel is a complex process with many variables that need to be understood before attempting to go back into the past. Understanding set events, alternate realities, butterfly effects, and predestination can only bring clarity to the process. By grasping the concept of time travel, we can understand its place in DC Comics lore and its importance to The Flash and his timeline.
