SUMMARY

The Krasnikov Metric, developed by Sergei Krasnikov of the Pulkovo Observatory, describes a theoretical framework for creating traversable wormholes that can maintain stability through an abundant supply of exotic matter. This concept was highlighted in a BBC news article from April 12, 2000, which referenced Krasnikov's work on wormholes. The key document for understanding this metric is "Toward a traversable wormhole," available at www.zamandayolculuk.com/cetinbal/pdfdosya/wh.pdf. Further details can be explored in the arXiv paper titled "gr-qc/9909016v4," which provides foundational insights into the theoretical underpinnings of Krasnikov's research.

PREREQUISITES
  • Understanding of general relativity principles
  • Familiarity with exotic matter concepts
  • Knowledge of wormhole physics
  • Ability to interpret academic papers in theoretical physics
NEXT STEPS
  • Read "Toward a traversable wormhole" by Sergei Krasnikov
  • Examine the arXiv paper "gr-qc/9909016v4" for foundational theories
  • Research the implications of exotic matter in cosmology
  • Explore current advancements in wormhole theories and metrics
USEFUL FOR

This discussion is beneficial for theoretical physicists, cosmologists, and researchers interested in advanced concepts of wormhole physics and the role of exotic matter in maintaining stability in such structures.

On 12.April 2000, BBC news http://news.bbc.co.uk/2/hi/science/nature/710812.stm, quoting an article in New Scientist (to which I don’t have access, and which is anyway usually sketchy on details), wrote that Sergei Krasnikov of the Pulkovo Observatory in St. Petersburg has found a way (presumably a metric by which a specific kind of “wormhole can create its own abundant supply of exotic matter” to stay open. I found “Toward a traversable wormhole” by Krasnikov at www.zamandayolculuk.com/cetinbal/pdfdosya/wh.pdf , but it is undated, so that except for the references telling me it is after 1999, I cannot tell if this latter article was written before or after the one to which New Scientist is referring. From the contents, I would guess before. Can anyone give me a link (preferably freely accessible, without having to sign up for anything) to an article with more details of this type of theoretical wormhole which Krasnikov has worked out, or is the pdf article cited above all that, with journalistic hyperbole, New Scientist is referring?
