Algorithmic bottlenecks in evolution: Genetic code, symbolic language, and the Great Filter hypothesis
Mikhail Prokopenko, Nihat Ay, Angelica Breviario +12
The Great Filter hypothesis proposes that the emergence of technological societies capable of interstellar travel depends on a small number of exceptionally hard and highly improba…
The Great Filter hypothesis -- a new Great Filter?
Darren J. Dougan
The Great Filter hypothesis is an extension of the Fermi Paradox: "If life is so common in the universe, why don't we see it?" The Great Filter theory posits there are multiple obs…
Searching for new physics using high precision absorption spectroscopy; continuum placement uncertainties and the fine structure constant in strong gravity
Chung-Chi Lee, John K. Webb, Darren Dougan +3
Searches for variations of fundamental constants require a comprehensive understanding of measurement errors. This paper examines a source of error that is usually overlooked: the…
Searching for new physics using high precision absorption spectroscopy; continuum placement uncertainties and towards the quasar PHL957
John K. Webb, Chung-Chi Lee, Dinko MilakoviÄ +3
Detecting or placing upper limits on spacetime variations of fundamental constants requires quantifying every potential source of uncertainty. We continue our previous study into t…
