At the end of Loki Season 2, Loki’s variant weaves all of time into a Yggdrasil-like structure, but how strong would this make him? to do that, we need to go over the MCU cosmology.
A **timeline** is the series of causes and effects associated with a universe, complete, a self-contained sequence of events. For example, in Universe 616’s timeline, Steve Rogers became Captain America, Thanos won, and Hulk brought everyone back. Note that the past cannot be changed, the present moves forward into the future, and the future is not determined. Also note that, in most, if not all, contexts, the terms *universe,* *timeline* and *reality* can be used interchangeably. For example, I could say “In 616’s universe, Tony Stark died,” or “In 616’s timeline, Tony Stark died.” The terms are interchangeable because every universe has a timeline, and every timeline has a universe. You cannot have one without the other.
Substantially, this means that a timeline is composed of an infinite number of dimensions, which are separate space-time continuums.
We can thus conclude that a Timeline is a multiversal+ structure.
2. The Sacred Timeline
The **Sacred Timeline** is the set or collection of universes that were isolated after the Multiversal War by He Who Remains. It is composed of many universes and their timelines, "stacked" atop one another. These realities shared the same baseline despite being different from one another, as they all led to the birth of He Who Remains and thus prevented the emergence of any Kang variant. This is confirmed by WoG statements, which affirm that multiple instances of time occur simultaneously, and these instances can generally be defined as different universes, that the Sacred Timeline resembles the intertwined strands of a rope and that small deviations can happen, but they do not stray meaningfully from the baseline, at least not enough to cause the birth of a Kang variant, so the TVA does not intervene. https://thedirect.com/article/loki-sacred-timeline-confusion-finale#:~:text=%3E%20,And This is further confirmed by Mr. Paradox, who says that "the true universe exists on the Sacred Timeline," not that the Sacred Timeline is the true universe, further supporting the claim that the Sacred Timeline is composed of multiple universes
The time heist in Endgame must have created multiple alternate timelines, which coexist within the Sacred Timeline because they do not diverge too far from the baseline.
In summary, the Sacred Timeline is a bundle of slightly different universes and timelines, all closely aligned and all leading to the same predetermined outcome, the birth of He Who Remains. For simplicity, we can refer to a structure like the Sacred Timeline as a macro-timeline composed of an infinite number of micro-timelines.
The term "Sacred Timeline" is also occasionally used to refer to the primary timeline of the MCU, designated as Earth-616.
Because of what was mentioned previously in the article, stemming from an interview with Loki’s writer Michael Waldron, we know that there are infinite instances of time happening simultaneously, and each of these can be seen as a different universe. The Sacred Timeline was described as resembling intertwined strands of a rope, with tiny fluctuations (branches) occurring constantly. The TVA monitors these timelines and only prunes branches that deviate enough to risk creating a new variant of Kang. https://thedirect.com/article/loki-sacred-timeline-confusion-finale#:~:text=%3E%20,And Since these small fluctuations happen at every moment in time and are allowed to persist if they don’t surpass the threshold of significant deviation, this means the Sacred Timeline contains an uncountably infinite number of closely related timelines branching continuously.
We can thus conclude that the Sacred Timeline is a 5th-dimensional structure.
The Multiverse is believed to be explained by the eternal inflation model https://youtube.com/clip/Ugkx7Ah9JDt_y14woy8PuZS-BT5Bnw9XugfV?si=nzMUv-o5ORIeCcf0, which suggests that the Multiverse may include universes that are not merely alternate timelines created by different choices or events. Instead, entirely separate, self-contained universes may have been born, universes that are not branches of one another and have no causal or temporal relationship. Although this has not been explicitly confirmed, this view aligns well with the current model of how the Multiverse functions in the MCU.
The **Multiverse** is the aggregate of all timelines in existence. It's composed of **macro-timelines**(each made of an uncountably infinite number of timelines), such as the Sacred Timeline, often compared to a tree, which are stated to be able connect to other trees through their branches https://www.murphysmultiverse.com/exclusive-loki-director-kate-herron-explains-marvels-interconnected-multiverse/. These branches represent timelines that deviate from a baseline, and they serve as the "connectors" between various macro-timelines https://www.murphysmultiverse.com/exclusive-loki-director-kate-herron-explains-marvels-interconnected-multiverse/.A branched timeline continues to branch further, just like in the Sacred Timeline. When a timeline deviates meaningfully enough, it no longer fits the baseline of its parent macro-timeline and thus forms a new macro-timeline. Furthermore, these branches can themselves continue branching, following the same logic, branching an uncountably infinite number of times. The End of Time contains all timelines and branches.
Put simply, the **Multiverse** is made up of an **uncountably infinite number of macro-timelines**, each capable of branching and connecting to others.
We can thus conclude that the Multiverse, and the End of Time are 6th-dimensional structures. #movies #video i
