When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

The study of gravitational dynamics interweaves the classical and quantum realisations of gravity, employing both traditional methods and modern amplitude techniques. At its core, the subject ...

Cast your mind back four years, and gravitational waves were the talk of the town. On September 14, 2015, the first detection of these ripples in space-time was made by the LIGO-Virgo collaboration, ...

Born shortly after Neil Armstrong's first steps on the Moon in 1969, my journey into space exploration has been entirely self-taught. A military stay in Mururoa sparked my formal education in space ...

There are two fundamental classes of theories required to describe the entirety of the Universe. On the one hand, there's quantum field theory, which describes electromagnetism and the nuclear forces, ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves ...

Many physicists assume that gravitons exist, but few think that we will ever see them. These hypothetical elementary particles are a cornerstone of theories of quantum gravity, which seek to unify ...

One of the things we often just accept about the world is that physical effects get weaker the farther away we get from them. Light sources appear dimmer, the gravitational force gets weaker, magnets ...
