DOW-UAP-D139 — Traversable Wormholes and Negative Energy

The report treats traversable wormholes as exact general-relativistic solutions that require exotic matter, while identifying the type, quantity, and production of negative energy as the central technical problem.

The identification, magnitude, and production of exotic matter are seen to be a key technical challenge

Its design method starts by specifying a desired wormhole geometry, calculating the required stress-energy, and then judging whether the result is physically plausible.

Given the desired geometry, use the general relativistic field equation to calculate the distribution of matter required to set up this geometry.

The report says a traversable throat must be supported by zero or negative energy density and/or outward tension.

this material must have zero or negative energy density and/or an outward radial tension that is greater than its energy density.

It argues that quantum field theory permits local negative-energy density or flux and lists squeezed states and the Casimir effect among candidate sources.

quantum field theory has the remarkable property of allowing states of matter containing local regions of negative energy density or negative fluxes

The report leaves capture and storage of negative energy to future work because the technical literature was sparse.

there is very little technical literature that addresses how to capture and store negative energy

It says high-intensity lasers can create extreme electromagnetic fields but that no known current physics shows how to give them the required tension.

It is not known how to increase the tension in these fields using current physics, but some new physics may provide an answer.

Laboratory squeezed-vacuum states alternate between negative and positive energy density while retaining positive time-averaged energy.

a squeezed vacuum state consists of a traveling electromagnetic wave that oscillates back and forth between negative energy density and positive energy density, but has positive time-averaged energy density.

A proposed mirror arrangement for separating squeezed-light pulses is presented as a concept, not a demonstrated wormhole-energy system.

In principle a set of rapidly rotating mirrors could be arranged to separate the positive and negative energy pulses from each other.

The moving-mirror dynamical Casimir effect is described as exceedingly small and rejected as an effective production route.

this effect is known to be exceedingly small, and it is not the most effective way to produce negative energy.

A one-kilometer Casimir-supported throat would require plate spacing smaller than a nuclear diameter, and the report says no known technology can make such a cavity.

There is no technology known today t hat can engineer a cavity with such minuscule plate separations.

The report distinguishes making small laboratory negative-energy effects from producing the large quantities relevant to wormhole engineering.

One knows how to make small quantities of negative energy in the lab. But one does not know if it is possible to make large quantities of negative energy.

A simple one-meter-throat estimate gives a negative equivalent mass about 0.71 Jupiter masses, while the report notes other geometries may reduce the integrated requirement.

Equation (9) shows that a mass of -0. 71 M1 will be required to build a wormhole 1-m in size.

The report says general relativity supplies geometric and material requirements but no assembly instructions for constructing a traversable wormhole.

general relativity theory only provides a recipe for the essential geometric and material ingredients required to open and maintain one, but not the required assembly instructions.

Its conclusion calls for empirical work because theory does not establish whether a negative-energy beam would create a traversable wormhole.

If one "zaps" a region of empty space with a beam of negative energy, will a traversable wormhole appear? One doesn't know.
