A scientist draws a diagram of the space-time continuum on a whiteboard.

Definition

1. Noun:
   • The four-dimensional coordinate system: A unified model that combines the three dimensions of space (length, width, height) and the one dimension of time into a single four-dimensional continuum. In this model, physical events are precisely located.

Usage

• The space-time continuum is a fundamental concept in Einstein's theory of general relativity.
• According to modern physics, massive objects can warp the space-time continuum.
• Scientists study how gravity affects the geometry of the space-time continuum.

Examples

Advanced Usage

• "Fabric of the space-time continuum": A metaphorical phrase describing the continuum as a malleable structure.
  • The black hole created a rip in the fabric of the space-time continuum.

Variants and Related Words

• Space-time (noun): Often used as a shorter form with the same meaning as "space-time continuum."
  • The equations calculate intervals in space-time.
• Continuum (noun): A continuous sequence in which adjacent elements are not perceptibly different, but the extremes are quite distinct.

Synonyms

• Space-time: The four-dimensional manifold.
• Four-dimensional continuum: A more technical synonym.

Related Concepts (Not Synonyms)

• General Relativity: The theory in which the space-time continuum is a central concept.
• Event: A point in the space-time continuum specified by its spatial and temporal coordinates.
