spaceorigin

Spaceorigin is a term used in cosmology and theoretical physics to denote the question of how space, and spacetime, came into existence. As a defined concept, it does not refer to a single established theory but to a family of ideas about the earliest moments of the universe and the possible pre-spacetime regime.

In the standard Big Bang framework, spacetime is described from a hot, dense state about 13.8 billion years ago, but the model does not by itself explain why spacetime exists or what preceded it. Several lines of inquiry explore whether spacetime is emergent from more fundamental degrees of freedom or processes.

Emergent spacetime approaches arise in various quantum gravity programs, where geometry is thought to originate from deeper quantum structures. Examples include notions that spacetime may arise from entanglement patterns in quantum systems, from discrete quantum geometry in loop quantum gravity, or from holographic ideas in which higher-dimensional spacetime emerges from lower-dimensional quantum information. Some string-theory-inspired scenarios also consider pre-geometric phases or dynamics that yield spacetime as an emergent phenomenon.

Certain cosmological proposals address pre-spacetime conditions. The no-boundary proposal by Hartle and Hawking and the concept of tunneling from nothing proposed by Vilenkin are among the ideas discussed for modeling the universe’s origin without a singular initial state. These proposals remain theoretical and debated, with ongoing questions about mathematical consistency and observational consequences.

As of now there is no empirical evidence for a definitive moment of spacetime creation. Research on spaceorigin intersects with philosophical questions about causality and nothingness, and future advances in quantum gravity and cosmology may help constrain or distinguish among proposed mechanisms for the origin of space.
