Documents / Official release
This Defense Intelligence Reference Document, DIA-08-1004-005, is dated 6 April 2010. The Defense Intelligence Agency's Defense Warning Office prepared it under the Advanced Aerospace Weapon System Applications program. It reviews proposed laboratory generators and detectors for high-frequency gravitational waves. It favors a piezoelectric approach for proof-of-concept tests, IR-excited molecules for an operational transmitter and the Li-Baker detector as the receiver. It estimates about 1.9 million bits per second over 7,000 km through the Earth and discusses timing standards and interplanetary navigation uses.
From the source:Release of 2026-09-18 Incident: 4/6/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD examines whether high-frequency gravitational waves could serve as a communications medium while avoiding the attenuation that limits radio-frequency systems. The report surveys proposed transmitter and detector concepts, argues that gravitational-wave communications could support secure point-to-point links, timing standards, and interplanetary navigation, and gives particular attention to laboratory generator concepts and the Li-Baker detector as possible building blocks for such a system. The document makes clear, however, that the entire concept depends on capabilities that had not been demonstrated in practice, including laboratory-scale generation and reliable detection of usable high-frequency gravitational-wave signals. It is an exploratory systems-oriented review built around a future communications concept.

refraction or bending of gravitational rays), backscatter, and/or other characteristics
can be modified by a material object's texture and internal structure. For example, the
change in polarization of a GW passing through a material object is discussed in Misner,
Thorne, and Wheeler (1973): "In the real universe there are spacetime curvatures due
not only to the energy of gravitational waves, but also more importantly to the material
[objects and structures] content of the universe ... its wavelength changes [based on
gravitational red shift] and [the gravitational wave] backscatters off the curvature to
some extent. If the wave is a pulse, then the backscatter will cause its shape and
polarization .... " It is difficult to theoretically establish the actual magnitude of the
changes, especially at very high frequencies (10 14 Hz and higher) and to quantify them
prior to HFGW generation/detection laboratory experiments.
4.5 2050 AND BEYOND
The phases of human space exploration may be divided into the following phases:
• Epoch 1 - Interplanetary Exploration
• Epoch 2 - Interstellar Exploration
• Epoch 3 - Intergalactic Exploration
• Epoch 4 - Universal Exploration
Each phase will have its own challenges and opportunities, but one can certa inly
specu late that the human need for connectedness and communication knows no
bounds. So any scope of expansion beyond Epoch 1 will have enormous challenges in
the area of communication . The vast distances involved will require some form of
communication that entai ls faster-than -l ight (FTL) propagation. While this is a highly
specu lative area, such schemes have been proposed for FTL HFGW. Both Fontana and
Mehalic (unpublished reports) have proposed models of the universe, such as the
trispace model, in which subluminal or luminal gravitational waves may couple into a
super- luminal "para llel universe" inside which FTL speeds are possible. Such as scheme
would be requ ired to communicate between star systems and galaxies if humankind is
to maintain any type of cohesive civilization. Without communications we have a history
of fractured civilization, and we slip into becom ing our own worst enemy. Universal
communication holds the lofty promise of universal peace.
