Interstellar Diplomacy
John Gertz
The Defense Department and NASA are investigating the possibility that aliens are currently surveilling Earth. This aligns with some search-for-extraterrestrial-intelligence (SETI)…
Engineering an Interstellar Communications Network by Deploying Relay Probes
John Gertz, Geoffrey Marcy
We develop a model for an interstellar communication network that is composed of relay nodes that transmit diffraction-limited beams of photons. We provide a multi-dimensional rati…
The Search for Deliberate Interstellar SETI Signals May Be Futile
John Gertz
For more than 60 years, the predominant SETI search paradigm has entailed the observation of stars in an effort to detect alien electromagnetic signals that deliberately target Ear…
The Drake Equation at 60: Reconsidered and Abandoned
John Gertz
Each of the individual factors of the Drake Equation is considered. Each in turn is either abandoned or redefined and finally reduced to a single new factor, fd, the fraction of te…
Strategies for the Detection of ET Probes Within Our Own Solar System
John Gertz
Arguments are reviewed in support of the hypothesis that ET would more likely send physical probes to surveil our Solar System and communicate with Earth than to communicate from a…
There's No Place Like Home (in Our Own Solar System): Searching for ET Near White Dwarfs
John Gertz
The preponderance of white dwarfs in the Milky Way were formed from the remnants of stars of the same or somewhat higher mass as the Sun, i.e., from G-stars. We know that life can…
Oumuamua and Scout ET Probes
John Gertz
Numerous advantages may accrue to ET from the use of probes for the conveyance of information relative to the alternative of beaming information electromagnetically from its home s…
ET Probes, Nodes, and Landbases: A Proposed Galactic Communications Architecture and Implied Search Strategies
John Gertz
Land-based beacons, information laden probes sent into our solar system, and more distal communication nodes have each been proposed as the most likely means by which we might be c…
Nodes: A Proposed Solution to Fermi's Paradox
John Gertz
Within the SETI community, a school of thought holds that ET might prefer to send information physically in so-called "probes," rather than by radio or optical beacon, in effect, a…
Post-Detection SETI Protocols & METI: The Time Has Come To Regulate Them Both
John Gertz
Regulations governing METI are weak or non-existent. Post-detection SETI protocols are non-binding and too general. Vastly increased SETI capabilities, Chinese involvement in the f…
ET Probes: Looking Here as Well as There
John Gertz
Almost all SETI searches to date have explicitly targeted stars in the hope of detecting artificial radio or optical transmissions. It is argued that extra-terrestrials (ET) might…
The Geometry of the Wigner Caustic and a Decomposition of a Curve Into Parallel Arcs
W. Domitrz, M. Zwierzyński
In this paper we study global properties of the Wigner caustic of parameterized closed planar curves. We find new results on its geometry and singular points. In particular, we con…
