International Conference Dark Matter & Stars 2026 - Public Lecture

Terrestrial telescopes are in crisis mode because of the imminent deterioration in the darkness of the night sky. The lunar surface allows a unique way forward that will be actively explored in the next decades. Gravitational wave telescopes will address the unexplored decihertz gravitational wave signals that will capture the history and growth of merging massive black holes, complementing the science achievable by current and planned gravitational wave observatories. The far side provides a unique radio-quiet environment for exploring our ultimate frontier, the dark ages, some 50 million years after the Big Bang, via low-frequency 21 cm interferometry to probe the beginnings of structure formation with the assembly of the first hydrogen clouds. Dark ages maps at unprecedented resolution will eventually probe the very nature of inflationary cosmology. Optical interferometers, operating at ultrahigh resolution and sensitivity in a space-like environment, will provide targets for the Habitable Worlds Observatory and eventually explore nearby Earth-like exoplanets for imaging and biological tracers to pose the ultimate question of whether we are alone in the Universe. Permanently cold and dark polar craters will provide potential sites for far-infrared telescopes to study the most distant galaxies in the universe. We will also use the spectrum of the cosmic microwave background radiation at terahertz frequencies to probe our cosmic origins.

Professor Joseph Silk is a British-American Astrophysicist with affiliations to Institute of Astrophysics of Paris in France, Oxford University and Johns Hopkins University in the USA.
