Parallel universes refer to alternate realities that exist alongside our own universe. They are often depicted as having similar physical laws and structures but differing in specific details, such as historical events or individual choices. The idea is that these universes run parallel to each other, much like parallel lines in geometry that never intersect.

Perpendicular universes, on the other hand, are a less commonly discussed concept and are often more speculative or fictional. The term suggests a different dimensional relationship, where these universes might intersect or interact at certain points, akin to how two lines can meet at a right angle.

In some interpretations, perpendicular universes could imply that they have fundamentally different physical laws or constants, leading to vastly different realities. This could allow for interactions or overlaps between the universes, unlike parallel universes, which remain distinct and separate.

45-degree universes are an even more abstract concept, often described as hybrid universes that share properties of both parallel and perpendicular universes.

Summary of Differences

• Interaction: Parallel universes do not interact with each other, while perpendicular universes may have points of intersection or interaction.
• Dimensionality: Parallel universes are often thought of as existing in the same dimensional space, whereas perpendicular universes suggest a different dimensional relationship.
• Physical Laws: Parallel universes typically share similar physical laws, while perpendicular universes might operate under entirely different rules.
