Galactic settlement of low-mass stars as a resolution to the Fermi paradox
Jacob Haqq-Misra, Thomas J. Fauchez
An expanding civilization could rapidly spread through the galaxy, so the absence of extraterrestrial settlement in the solar system implies that such expansionist civilizations do…
Can Deep Altruism Sustain Space Settlement?
Jacob Haqq-Misra
Space settlement represents a long-term human effort that requires unprecedented coordination across successive generations. In this chapter, I develop a comparative hierarchy for…
Population Growth, Energy Use, and the Implications for the Search for Extraterrestrial Intelligence
Brendan Mullan, Jacob Haqq-Misra
Von Hoerner (1975) examined the effects of human population growth and predicted agricultural, environmental, and other problems from observed growth rate trends. Using straightfor…
Policy options for the radio detectability of Earth
Jacob Haqq-Misra
The METI risk problem refers to the uncertain outcome of sending transmissions into space with the intention of messaging to extraterrestrial intelligence (METI). Here, I demonstra…
The Drake Equation as a Function of Spectral Type and Time
Jacob Haqq-Misra, Ravi Kumar Kopparapu
This chapter draws upon astronomical observations and modeling to constrain the prevalence of communicative civilizations in the galaxy. We discuss the dependence of the Drake equa…
Why do we find ourselves around a yellow star instead of a red star?
Jacob Haqq-Misra, Ravi Kumar Kopparpu, Eric T. Wolf
M-dwarf stars are more abundant than G-dwarf stars, so our position as observers on a planet orbiting a G-dwarf raises questions about the suitability of other stellar types for su…
