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, ...

If the recent discovery of gravitational waves emanating from the early universe holds up under scrutiny, it will illuminate a connection between gravity and quantum mechanics and perhaps, in the ...

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 ...

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, ...

Whenever any two things in the Universe interact at the same location in spacetime, one thing always remains true about that interaction: it conserves energy. But what if one of those things is an ...

The elusive, yet seemingly inevitable, quantum nature of gravity may finally be demonstrated experimentally. Two separate groups in the UK; Chiara Marletto and Vlatko Vedral at the University of ...

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 ...
