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 Milaković +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…

Measuring the fine structure constant on white dwarf surfaces; uncertainties from continuum placement variations

Chung-Chi Lee, John K. Webb, Darren Dougan +2

Searches for variations of fundamental constants require accurate measurement errors. There are several potential sources of errors and quantifying each one accurately is essential…
