What you'll learn

  • Learn the state of the art of Traversable Wormholes.

Course content

5 sections • 22 lectures • 2h 6m total length

  • Summary - Part 17:49

    Explore traversable wormholes as stargates enabling faster-than-light travel by engineering space-time with exotic matter under Einstein's relativity. Compare them to black holes and non-traversable bridges and discuss energy conditions.

  • Summary - Part 28:26

    Analyze Newtonian rocket propulsion, mass ratios, and high specific impulse to minimize propellant. Explore traversable wormholes and exotic matter with negative energy density for potential ftl travel.

  • Traversable Wormholes - Part 16:34

    Define a traversable wormhole by specifying the desired geometry and using general relativity to derive the required matter distribution in a Lorentzian metric, including negative energy density and exotic matter.

  • Course Engagement2:04

    Join a warm, engaging introduction by a researcher of hidden knowledge, inviting discussion and access to couponed or free Udemy courses to expand consciousness.

  • Traversable Wormholes - Part 27:04

    Explore the geometry and travel times through traversable wormholes, describing proper time, proper distance, throat velocity, and embedding diagrams, plus Gauss-Bonnet topology and energy-condition implications.

  • The Stargate Solution6:32

    Design a traversable flat-face wormhole from two copies of flat Minkowski space joined by a thin shell, connecting two remote space-time regions with zero surface energy and tensions.

  • What a Wormhole Looks Like in the Real World2:33

    Examine how exotic matter creates repulsive gravity that deflects light through a traversable wormhole's throat, revealing a spherical entrance and a mirror region of four-dimensional space-time.

Requirements

  • Come with an open mind.
  • Some prior knowledge is physics recommended.

Description

In this course we will explore the state of the art of Traversable Wormholes. The implementation of faster-than-light (FTL) interstellar travel via traversable wormholes generally requires the engineering of spacetime into very specialized local geometries. The analysis of these via Einstein's General Theory of Relativity, plus the resultant equations of state, demonstrates that such geometries require the use of "exotic" matter.

It has been claimed that since such matter violates the energy conditions, FTL spacetimes are not plausible. 

However, it has been shown that this is a spurious issue. The identification and production of exotic matter are seen to be a key technical challenge. These issues are reviewed and summarized here, and an assessment on the present state of their resolution is provided.

Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. Many scientists postulate that wormholes are merely projections of a fourth spatial dimension, analogous to how a two-dimensional (2D) being could experience only part of a three-dimensional (3D) object.

Theoretically, a wormhole might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even different universes.
