Remember that time in the Lord of the Rings lore when the dwarves of Moria dug too greedily and too deep, unearthing the Balrog, an ancient horror not meant to roam free in the modern age? Cosmic ...

Physicists in the US and Singapore are the first to use light from distant galaxies to perform a systematic search for cosmic strings — massive structures that may have been created just after the Big ...

Topology originated from the classification of geometric structures in mathematics, and have prevailed in a variety of branches of physics, ranging from the early electronic topological insulator to ...

Pictures are the key to new insights in the field of astrophysics. Such images include simulations of cosmic events, which astrophysicists at UZH use to investigate how stars, planets and galaxies ...
