Advanced Space Propulsion Based on Vacuum (Spacetime Metric) Engineering (entered by Rep. Burchett)

U.S. House Committee Repository · 17 pages · text from the file's own layer

This is an unclassified Defense Intelligence Reference Document (DIA-08-1003-015), dated 29 March 2010. The Defense Intelligence Agency prepared it under the Advanced Aerospace Weapon System Applications (AAWSA) Program, and Rep. Burchett entered it into the House committee record. The paper uses a general relativity metric tensor approach to look at how engineering spacetime might enable propulsion, including warp drives, apparent superluminal travel, reduced effective mass and antigravity. It finds these ideas consistent with physics but far beyond present engineering capability.

therefore time intervals are seen as lengthening and processes as running slower,2 one
consequence of which is redshift of emission lines. Should such a time-slowed condition
be engineered in an advanced aerospace application, an individual who has spent time
within such a temporally modified field would, when returned to the normal
environment, find that more time had passed than could be experientially accounted
for.
Conversely, for an engineered spacetime associated with an advanced aerospace craft
in which ‘R >1, time flow within the altered spacetime region would appear sped up
to an external observer, while to an internal observer external time flow would appear
to be in slow motion. A corollary would be that within the spacetime-altered region,
normal environmental sounds from outside the region might cease to be registered,
since external sounds could under these conditions redshift below the auditory range.
An additional implication of time speedup within the frame of an exotic craft technology
is that its flightpath that might seem precipitous from an external viewpoint (for
example, sudden acceleration or deceleration) would be experienced as much less so by
the craft's occupants. From the occupants' viewpoint, observing the external
environment to be in relative slow motion, it would not be surprising to consider that
one's relatively modest changes in motion would appear abrupt to an external observer.
Based on the second entry in Table 1 (frequency), yet another implication of an
accelerated timeframe due to craft-associated metric engineering that leads to
ig00 >1, frequencies associated with the craft would for a remote observer appear to
be blueshifted. Corollary to observation of such a craft is the possibility that there
would be a brightening of luminosity due to the heat spectrum blueshifting up into the
visible portion of the spectrum (see Figure 1).

With regard to the third entry in Table 1 (energy), in a spacetime-altered region,
