## Time Travel Sources

### Time Stone

The Time Stone has shown to have the ability to rewind time in a given area seeing time unfold. The wielder of the time stone can choose to be unaffected by the manipulation of time from the Time Stone. Sorcerers such as Doctor Strange can cast spells to make others unaffected by a reversal of time, as he did to Wong at the Battle at the Hong Kong Sanctum. Some sorcerers can have their minds unaffected by the time reversal, and eventually build up the willpower to break free from the spell, as Kaecilius and his followers did, likely due to the power given to them from the Dark Dimension.

Time loops can also be cast. The participants' body will be reset, even if one is killed. Their consciousnesses however will continue on until the loop is ended. This was later used by Doctor Strange before the Battle of Titan to know how to defeat Thanos in the long term.

### Archimedes' Dial

In 213 BC, during the siege of Syracuse, the Greek mathematician Archimedes was working on a dial that would allow him to locate fissures in time and possibly travel into the past or the future. One half of the device was finished when his assistant informed him about a dragon flying in the sky. Confused, Archimedes stepped outside and saw a giant flying machine burning and crashing on the beach. Archimedes came closer to investigate and took a small mechanical device from the corpse of one of the people who died in the crash. A man and a woman then appeared in front of him, holding a device identical to the one he was working on. Archimedes asked the strangers how far they traveled, and the man replied "Two thousand years". The strangers then had a brief argument, for the man was injured and the woman wanted him to return to their time so he could be healed, but the man was reluctant. The woman punched the man, knocking him unconscious, and the strangers departed in another, smaller mechanical dragon. Realizing that time travel was real, Archimedes split his device into two pieces. One was captured by the Romans and ended up at the bottom of the sea when the ship that was carrying it sunk in a storm. The other was buried with Archimedes in his tomb.

By 1944 the Nazi scientist Jürgen Voller was searching for Archimedes' dial. During an evacuation of a castle in Germany, a group of soldiers led by Voller and Colonel Weber discovered a hoard of precious antiquities, including the dial and the fabled Spear of Destiny. After loading the loot on a train the Nazis departed, hoping to bring their prize to Adolf Hitler. However, Voller discovered the Spear was fake, and tried to convince Weber about the dial's power, but the Nazi officer dismissed his theories as rubbish. The dial was eventually stolen by the American archeologist Indiana Jones and his colleague Basil Shaw.

Jones kept possession of the dial until 1969, when neo-Nazis led by Voller set out to reunite the two halves in order to assassinate Adolf Hitler so that a more competent Führer could win World War II for Nazi Germany. Voller and his men battled Jones and Shaw's daughter Helena for possession of the dial, ultimately resulting in Voller reassembling the dial and attempting to travel in an airplane through a time fissure to 1939 with the captive Jones and the stowaway Helena. However, what nobody realized was that the dial was only ever meant to allow travel to 213 BC. The group arrived at the Siege of Syracuse, closing the causal loop and resulting in Voller's death. Helena forced Jones to return to 1969 with her, ensuring that history would not be further altered by their presence.

### Quantum Realm

In 2023, in the aftermath of the Snap, the Avengers tried to find a way to undo Thanos' actions. However, the possibility would come 5 years later with the reappearance of Scott Lang who, due to the exotic physics of the Quantum Realm, informed the Avengers time worked differently in the Quantum Realm and if they could navigate it then they could jump into a different moment in time, before Thanos. With the help of Tony Stark and Bruce Banner, the Avengers were able to build a time machine and suits to execute the Time Heist.

With the information on the Infinity Stones' whereabouts, the Avengers traveled back to 2012, 2013 and 2014 in order to fulfil their goal. However, their actions in the past would create alternate timelines so all the changes made in the past would not affect their own reality. Once an unplanned travel to 1970 got carried out, the team returned to the present to use the Infinity Stones they collected and successfully undo the Snap through the Blip.

However, inadvertently, Thanos from the alternate 2014 reality traveled to 2023 using the time machine the Avengers used in order to use the Infinity Stones and accomplish his agenda. After the Battle of Earth, which ended with the death of Iron Man and the 2014 Thanos, Steve Rogers went back to the realities the team had created to return the Infinity Stones as Banner had promised to the Ancient One so the realities would not be affected by the Stones' absence. Rogers would later decide to stay back in 1949 to live with Peggy Carter returning to 2023 to pass the mantle of Captain America to Sam Wilson.

## Trivia

* Due to the concept of Movie Wars being a crossover beetween every movie franchise, multiple franchises coexist within the same universe, and this makes the concept of time travel even more confusing, as there are different ways of time travel in different movies. In movies like the *Back to the Furure* trilogy or *Men in Black III,* the current reality is altered, as such, certain events are changed and certain individuals are completely ereased from existence. However, movies such as *Avengers: Endgame* feature a different form of time travel, in which alternate realities are created, while the current timeline remains the same. It's possible that this is due to different objects being used for time travel. The alternate realities might also be related to the Infinity Stones.
