DOW-UAP-D138 — Warp Drive, Dark Energy, and Extra Dimensions

The report says wormholes have no observational evidence and treats both wormholes and warp drive as theoretical spacetime manipulations.

Although no observational evidence of wormholes exists, theoretically they can exist as a valid solution to general relativity.

It grounds the warp-drive discussion in Alcubierre’s 1994 metric but says subsequent papers generally did not explain how to create the required bubble.

However, these papers do not typically address how one might actually create the necessary spacetime bubble.

The authors acknowledge that dark energy’s nature, origin, and means of creation were not understood.

Although we know what dark energy does, we do not yet fully understand its nature. We do not understand why it exists or how it is created

The conventional Alcubierre calculation requires enormous negative energy even for low bubble speeds, which the report calls a daunting engineering result.

Engineering a warp drive bubble is quite daunting given these results.

When a finite spacecraft mass is included, the report’s example yields a bubble speed of about 5.16 micrometers per second, slower than a garden snail.

Vwarp ~ 1.72 x 10- 14 (or 5. 16 x 10- 6 m/s). Garden snails can crawl faster than this.

The proposed alternative assumes a sufficiently advanced technology could change an extra dimension and thereby alter local dark-energy density; the report calls this an early-stage mechanism.

A sufficiently advanced technology with the capacity to directly interact with and manipulate an extra dimension would be able to locally adjust the dark energy density in a given region of spacetime.

The model simplifies higher-dimensional geometry to a circular extra dimension and says a fuller Calabi-Yau treatment might become necessary if the research matured.

At these early stages of investigation, the additional circular dimension represents an adequate approximation.

The report’s proposed warp bubble depends on an undeveloped technology that could manipulate field content to create artificial vacuum-energy minima around a spacecraft.

What this requires is a technology that would allow us to artificially manipulate the field content illustrated in Figure 7, shifting the location of the minimum.

Its light-speed example requires raising the local Hubble expansion factor by 10^26.

H must be increased by a factor of 10 26 to achieve a local expansion of space equivalent to the speed of light.

The corresponding model raises the cosmological-constant energy density by 10^52 and then assumes an extremely thin shell to reduce total energy.

the cosmological constant, an expression which characterizes the energy density of space, must be increased by a factor of 10 52

Even after the model’s claimed 10^8 reduction, the report says its energy needs remain beyond the foreseeable future.

the energies are still far in excess of those available in the foreseeable future.

The proposed laboratory path is explicitly introduced as pure speculation and assumes a device that could produce dark-energy-like negative pressure.

At this point we take a diversion into pure speculation as to what technological advancements may be necessary to build a device that might test our dark energy theory.

The report says prototype work first requires a better understanding of dark energy and confirmation that extra dimensions are real.

Other crucial developments include determining whether extra dimension are, in fact, real.

The conclusion says controlling extra dimensions might enable exotic propulsion only many years in the future and explicitly says the prospect is uncertain.

This is by no means a certainty
