🌌 What Is a Parallel World?

A parallel world is a hypothetical universe that exists outside or alongside our own, possibly with different:

• Physical laws
• Histories
• Timelines
• Versions of you or events

These are part of what’s called the “multiverse” — a collection of multiple possible universes.

🧠 Scientific Theories That Support Parallel Worlds

1. 🧩 Many-Worlds Interpretation (Quantum Physics)

• Every time a quantum event occurs (like a particle spin), all possible outcomes happen in separate, branching universes.
• Example: If you flip a coin, one universe sees “heads,” another “tails.”
• So, there could be infinite versions of you, living all possible timelines.

Origin: Hugh Everett, 1957
Related to: Schrödinger’s cat — alive and dead in separate worlds.

2. 🔁 Cosmic Inflation Theory (Cosmology)

• After the Big Bang, space expanded rapidly — but in some models, it never stopped expanding in certain regions.
• This leads to “bubble universes,” each with possibly different constants, particles, and dimensions.

3. 🕳️ String Theory / Brane Cosmology

• Suggests that our universe is a 3D “brane” floating in a higher-dimensional space.
• Other branes (universes) could be nearby — even interact through gravity or collisions.

4. 🌀 Black Hole Theory

• Some physicists theorize that every black hole might contain a new universe inside.
• So, each black hole in our universe could be a gateway to another entire world.

🧪 So, Is It Real?

• Mathematically possible under many theories.
• But there is no direct evidence yet.
• It’s extremely hard to test — other universes may be unreachable, even if they exist.
