Multiverse Predictions for Habitability: The Habitability of Exotic Environments
McCullen Sandora
The relative abundances of exotic environments provides us with (uninformed) bounds on the habitability of those environments relative to our own, on the basis that our presence he…
Information Gain as a Tool for Assessing Biosignature Missions
Benjamin Fields, Sohom Gupta, McCullen Sandora
We propose the mathematical notion of information gain as a way of quantitatively assessing the value of biosignature missions. This makes it simple to determine how mission value…
Multiverse Predictions for Habitability: Stellar and Atmospheric Habitability
McCullen Sandora, Vladimir Airapetian, Luke Barnes +1
Stellar activity and planetary atmospheric properties have the potential to strongly influence habitability. To date, neither have been adequately studied in the multiverse context…
Multiverse Predictions for Habitability: Planetary Characteristics
McCullen Sandora, Vladimir Airapetian, Luke Barnes +1
Recent detections of potentially habitable exoplanets around sunlike stars demand increased exploration of the physical conditions that can sustain life, by whatever methods availa…
Multiverse Predictions for Habitability: Element Abundances
McCullen Sandora, Vladimir Airapetian, Luke Barnes +2
We investigate the dependence of elemental abundances on physical constants, and the implications this has for the distribution of complex life for various proposed habitability cr…
Biosignature Surveys to Exoplanet Yields and Beyond
McCullen Sandora, Joseph Silk
Upcoming biosignature searches focus on indirect indicators to infer the presence of life on other worlds. Aside from just signaling the presence of life, however, some biosignatur…
OWL-MOON : Very high resolution spectro-imaging and Earth-Moon interferometry: exoplanets to cosmology
J. Schneider, J. Silk, F. Vakili +5
We address three major questions in astronomy, namely the detection of biosignatures on habitable exoplanets, the geophysics of exoplanets and cosmology. To achieve this goal, two…
Multiverse Predictions for Habitability: Fraction of Life that Develops Intelligence
McCullen Sandora
Do mass extinctions affect the development of intelligence? If so, we may expect to be in a universe that is exceptionally placid. We consider the effects of impacts, supervolcanoe…
Multiverse Predictions for Habitability: Fraction of Planets that Develop Life
McCullen Sandora
In a multiverse context, determining the probability of being in our particular universe depends on estimating its overall habitability compared to other universes with different v…
Multiverse Predictions for Habitability: Number of Potentially Habitable Planets
McCullen Sandora
How good is our universe at making habitable planets? The answer to this depends on which factors are important for life: Does a planet need to be Earth mass? Does it need to be in…
