The most awaited movie in Hollywood in the last decade was 'Avengers: Endgame' which was released in April. The excitement was sparked by the previous installment of Marvel Cinematic Universe, Avengers: Infinity War. Where the villain Thanos (Josh Brolin) brings six Infinity Stones (Soul, Time, Space, Mind, Reality and Power) into his possession and literally makes half the creatures of the universe disappear. Among them were half superheroes.
As a result, the challenge for Endgame was to bring back half the animals, especially the Marvel superheroes. That process has disappointed many, and made some happy. This is a very old idea used - time travel or time travel. It can be said that the discussion on ‘time travel’ started from the early days of science fiction. Even classic science masters have discussed this. As a result, there is a lot of debate about going back to the past and changing the present. The important aspect of this movie is that the old masters go to the quantum level instead of science and match the answer to the puzzle.
