Parallel universes, or **alternate realities**, are hypothetical universes co-existing with our own, often discussed in the context of the **multiverse** theory. This concept suggests that numerous universes exist, each with different configurations of matter and laws of physics. 

There are various levels of parallel universes:
- **Level 1**: Identical copies of Earth exist in an infinite universe.
- **Level 2**: Universes formed from different inflationary processes.
- **Level 3**: Every quantum possibility creates a new universe.
- **Level 4**: Universes governed by different mathematical laws altogether[1][2][4].

Are there any historical theories or myths that predated the modern concept of parallel universes

Historical theories and myths that predate the modern concept of parallel universes often involve creation myths and cosmological ideas. Ancient Egyptian, Greek, and Norse myths describe the universe's emergence from chaos, highlighting themes of order from disorder and cyclical existence[1]. In addition, some interpretations of Buddhist and Hindu cosmologies suggest overlapping worlds, akin to parallel universes[3]. These narratives, while not explicitly about parallel universes, reflect humanity's attempts to understand the cosmos in ways that resonate with modern multiverse theories.

How do scientists propose to detect parallel universes

Scientists propose several methods to detect parallel universes:

1. **Cosmic Microwave Background (CMB) Anomalies**: Some researchers suggest that anomalies in the CMB, like the "Cold Spot," could indicate a collision between our universe and another, potentially providing evidence of parallel universes[2].

2. **Quantum Mechanics**: The many-worlds interpretation of quantum mechanics suggests that every quantum event spawns new universes. Although this theory is difficult to test directly, it provides a framework for considering parallel universes[4].

3. **Gravitational Effects**: Theoretical models propose that parallel universes might interact with our universe through gravity, potentially detectable through precise measurements of gravitational forces[1].

What is the "mirror world" theory and how does it explain dark matter

The "mirror world" theory proposes the existence of a parallel universe composed of mirror particles that are copies of known particles in our universe. This theory suggests that these mirror particles interact with our world only through gravity, potentially explaining dark matter as a component of this mirror world[1][2]. The theory aims to address the "Hubble tension," a discrepancy in the measured expansion rate of the universe, by introducing a new cosmological model that includes this mirror world[1][4]. While intriguing, the theory lacks direct evidence and remains speculative[1][2].
