This page is in construction, and is meant to stimulate SETI research on black holes, X-Ray binaries (XRB) and star lifting. It was initiated by Clément Vidal (2011).
Contents
Situation
The Search for Extra-Terrestrials (SETI) has been unsuccessful so far.
Problems
- Can we find evidence of control in the XRB's energy flow?
Energy flow regulation or control is a necessary condition for the growth, maintenance, evolution and reproduction of complex systems (see e.g. Aunger 2007; Chaisson 2011). Are some XRBs displaying such a feature?
- How can we distinguish a natural process from an artificial and unknown one?
Accretion is an ubiquitous astrophysical process in galaxy and planetary formation, so XRBs may simply always be natural. Let me however introduce an analogy. Fission can be found in natural forms, as well as fusion, which is one of the core energetic processes in stellar evolution. Yet, humans try to copy them, and would greatly benefit to -always- control them. So it is not because a process is known to be natural that its actual use is not driven by an intelligence.In fact, the situation may be even more subtle. The formation of XRBs might be natural, but controlled or taken over by ETIs, like a waterfall is a natural energy source humans can harness with damps. So, how can we develop criteria for natural versus artificial? Non-equilibrium thermodynamics, systems theory, artificial life, etc. because of their general concepts and applicability, will certainly provide key conceptual frameworks. Metrics like Freitas' sentience quotient or Chaisson's (2001, 2003) energy rate density are certainly very promising, and a KII-BΩ civilization should score high on them. Those metrics also indicate that the distinction natural versus artificial may be of a continuous nature.
- What is the origin, evolution, fate and possible migration of XRB?
With this question I mean that a compelling argument for the existence of advanced ETIs will most likely come from an evolutionary and global cosmic understanding of natural and possibly artificial stellar evolution in our and other galaxies. Yes indeed, humanity's SETI is just getting started.
