  author={Charles H. Bennett and Robin D. Hanson and C. Jess Riedel},
  journal={Foundations of Physics},
In their article, ‘That is not dead which can eternal lie: the aestivation hypothesis for resolving Fermi’s paradox’, Sandberg et al. try to explain the Fermi paradox (we see no aliens) by claiming that Landauer’s principle implies that a civilization can in principle perform far more ( $${\sim } 10^{30}$$ times more) irreversible logical operations (e.g., error-correcting bit erasures) if it conserves its resources until the distant future when the cosmic background temperature is very low… Expand
Limits of Detecting Extraterrestrial Civilizations
This work views SETI as a detection problem— a yes or no answer to the question ‘was an extraterrestrially-engineered process detected from a given spacetime region?’ and presents the general optimization problem for constructing the optimal decision function for given ETI processes ( processes engineered by ETI) that minimizes false negatives while guaranteeing a chosen threshold of false positives.

Interstellar Communication Network. I. Overview and Assumptions
It has recently been suggested in this journal by Benford (2019) that "Lurkers" in the form of interstellar exploration probes could be present in the solar system. Similarly, extraterrestrialExpand
The Edges of Our Universe
This paper explores the fundamental causal limits on how much of the universe we can observe or affect. It distinguishes four principal regions: the affectable universe, the observable universe, theExpand


That is not dead which can eternal lie: the aestivation hypothesis for resolving Fermi's paradox
If a civilization wants to maximize computation it appears rational to aestivate until the far future in order to exploit the low temperature environment: this can produce a $10^{30}$ multiplier ofExpand
The thermodynamics of computation—a review
Computers may be thought of as engines for transforming free energy into waste heat and mathematical work. Existing electronic computers dissipate energy vastly in excess of the mean thermalExpand
Logical reversibility of computation
This result makes plausible the existence of thermodynamically reversible computers which could perform useful computations at useful speed while dissipating considerably less than kT of energy per logical step. Expand
Evolution of the cosmic microwave background
We discuss the time dependence and future of the cosmic microwave background (CMB) in the context of the standard cosmological model, in which we are now entering a state of endless acceleratedExpand
