The article explores the concept of time travel in the Back to the Future universe, using Neo4j as a tool to model and analyze it. The "forking" conception of timelines is used, where each time travel event creates a new timeline. The article discusses how this affects the behavior of time travelers, including the creation of ripples that capture them and move them between timelines. It also explores how to use Neo4j to create nodes for time travelers, events, places, and relationships between them, as well as Cypher queries to find ripple events. The article concludes by referencing a free ebook on graph databases to learn more about using Neo4j for complex challenges.
