Multiverse theory
Multiverse theory suggests that infinite universes with slight variations exist, each creating different outcomes. It implies our universe is just one of countless others, possibly with distinct laws.

String theory
String theory proposes that particles are actually one-dimensional "strings" vibrating at different frequencies, allowing for extra dimensions beyond the observable four, hinting at a deeper fabric of reality.

Many-worlds interpretation
In quantum mechanics, this theory proposes that every decision or event creates new universes, ultimately creating infinite parallel realities with alternate outcomes, challenging our concept of a single reality.

Simulation hypothesis
The simulation hypothesis argues that our reality might be an advanced simulation by a higher civilisation, suggesting that everything — including ourselves — could be artificially constructed within a supercomputer.

Holographic universe theory
Holographic universe theory puts forward the idea that our 3D universe is a projection of 2D data on a distant surface, implying reality is like a hologram rather than a tangible entity.

Quantum immortality
Quantum immortality is a thought experiment that suggests consciousness might always continue in alternate realities where one survives, so from a personal view, death might never be experienced.

Eternal inflation
Eternal inflation suggests that our universe is one bubble in an eternally expanding multiverse, where each "bubble" universe could have different physical constants and rules.

Cyclic universe theory
This theory proposes that the universe undergoes endless cycles of expansion and contraction, negating the need for a definitive beginning or end, unlike the Big Bang theory.

Brane cosmology
Brane cosmology implies that our universe is a 3D "brane" within a higher-dimensional space, where other branes (universes) may exist and interact, creating phenomena like gravity.

Retrocausality
Retrocausality implies that future events could influence the past, challenging our linear understanding of time and causality. It also suggests a more interconnected structure of past, present and future.
