After the devastating events of Avengers: Infinity War (2018), the universe is in ruins. With the help of remaining allies, the Avengers assemble once more in order to reverse Thanos’ actions and restore balance to the universe.

Time Travel Concepts
Multiverse
The Avengers’ time travel to collect the Infinity Stones creates alternate timelines, where changes in the past result in separate, branching realities rather than altering the original timeline.
Temporal Anchoring
The Avengers are emotionally anchored to specific events or relationships in their original timeline, motivating their actions to restore what was lost during the Blip.
Temporal Gravity
Key points in the timeline, like the Battle of New York or Vormir, act as gravitational nodes, drawing the Avengers to pivotal events where major consequences play out.
The Cost of Change
Actions like Natasha sacrificing herself to retrieve the Soul Stone, or Steve Rogers choosing to remain in the past with Peggy Carter, demonstrate the high personal costs of time manipulation.
Butterfly Effect
The Avengers’ actions, such as Loki escaping with the Tesseract, result in significant changes to the alternate timelines they interact with, as seen in Loki (TV series).
Causal Loop
Steve Rogers’ choice to return to the past and live with Peggy Carter retroactively fulfills his arc in a way that suggests his actions were always part of the timeline.
Time-Locked Zones
Certain rules prevent altering specific elements of the timeline, such as the impossibility of bringing Natasha back from the Soul Stone’s sacrifice.
Temporal Fusion
By returning the Infinity Stones to their respective points in time, the Avengers seek to prevent fusion or destabilization of timelines caused by their interference.
Temporal Decay
The film indirectly explores this concept when the Ancient One warns Bruce Banner that removing an Infinity Stone from the timeline would destabilize that reality, leading to potential decay or collapse.
Chrono-Ghosting
The Avengers’ knowledge and experience from their original timeline are brought into alternate realities, influencing decisions and interactions in the past.
Recursive Memory
Characters like Tony Stark and Steve Rogers recall key moments from their original timeline, which guide their actions in the past to ensure the mission’s success.
Reverse Causality
Tony Stark’s creation of the time travel device enables the Avengers to collect the Infinity Stones, setting in motion events that ultimately lead to his sacrifice and the restoration of the timeline.
Temporal Sabotage
Actions like Thor taking Mjolnir from the past or Loki’s escape with the Tesseract disrupt alternate realities, creating further complications and setting up new conflicts.
Causal Loop
By traveling to pivotal points in history, the Avengers repeatedly revisit the same key moments, such as the Battle of New York, to reshape events without rewriting the original timeline.
Time as a Character
Time itself is central to the story, functioning as both an ally and an obstacle, with rules that shape the narrative and the Avengers’ actions.
