The Effect of Cultural Drift on Interstellar Colonization
Often called the Fermi Paradox, the apparent failure of other intelligent species to have invited humanity to join a galactic civilization suggests that intelligence may be very rare in the cosmos,

If the Universe Is Teeming with Aliens ... WHERE IS EVERYBODY?: Fifty Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life
Given the fact that there are perhaps 400 billion stars in our Galaxy alone, and perhaps 400 billion galaxies in the Universe, it stands to reason that somewhere out there, in the 14-billion-year-old
A Computational Analysis of Galactic Exploration with Space Probes: Implications for the Fermi Paradox
Temporal explanations to the Fermi paradox state that the vast scale of the galaxy diminishes the chances of establishing contact with an extraterrestrial technological civilization (ETC) within a
Eavesdropping on radio broadcasts from galactic civilizations with upcoming observatories for redshifted 21 cm radiation
The question of whether intelligent life exists elsewhere is one of the fundamental unknowns about our Universe. Over the past decade extra-solar planets have been discovered, providing new urgency
A failure of serendipity: the Square Kilometre Array will struggle to eavesdrop on human-like extraterrestrial intelligence
Abstract The Square Kilometre Array (SKA) will operate in frequency ranges often used by military radar and other communications technology. It has been shown that if extraterrestrial intelligences

This paper argues for the necessity of long-term thinking when contemplating the problem of intelligence in the universe and provides arguments for a postbiological universe, based on the likely age and lifetimes of technological civilizations and the overriding importance of cultural evolution as an element of cosmic evolution.
A protocol for messaging to extraterrestrial intelligence
Slingshot dynamics for self-replicating probes and the effect on exploration timescales
Abstract Interstellar probes can carry out slingshot manoeuvres around the stars they visit, gaining a boost in velocity by extracting energy from the star's motion around the Galactic Centre. These
Biosignatures and the Search for Life on Earth
Earth is the only life-hosting planet in the Universe that we currently know of; however, it is just a matter of time until other Earth-like planets are detected. At that time, by analysing their

Abstract Many reasons for why extraterrestrial intelligences might avoid communications with our civilization have been proposed. One possible scenario is that all civilizations follow the lead of

In supernova (SN) spectroscopy relatively little attention has been given to the properties of optically thick spectral lines in epochs following the photosphere’s recession. Most treatments and
