Summary

Traversable wormholes require exotic matter, but this study quantifies its minimal amount. We show that spacetime geometries can support traversable wormholes using arbitrarily small quantities of exotic matter.

Area of Science:

  • Theoretical physics
  • General relativity
  • Quantum gravity

Background:

  • Traversable wormholes necessitate exotic matter, defined by violations of the averaged null energy condition.
  • Existing theorems do not quantify the total amount of exotic matter required for wormholes.

Purpose of the Study:

  • To develop a quantitative measure for exotic matter in spacetime.
  • To demonstrate that traversable wormholes can be supported by minimal amounts of exotic matter.

Main Methods:

  • Formulating a novel measure for quantifying energy condition violations.
  • Analyzing spacetime geometries to assess exotic matter requirements.

Main Results:

  • A method for quantifying the 'total amount' of exotic matter in a spacetime has been developed.

Related Experiment Videos

  • The existence of traversable wormhole geometries supported by arbitrarily small quantities of exotic matter is demonstrated.

    • Conclusions:

    • The quantitative analysis of exotic matter is crucial for understanding traversable wormholes.
    • The findings suggest that exotic matter requirements for traversable wormholes may be less prohibitive than previously assumed.
