The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe, conveyed through the exchange of virtual bosons. In electromagnetism, the ...

The Universe as Tempo'We have understood the speed of light as merely a 'speed limit.' But what if it is the very 'tempo at which spacetime is updated'? This universe is not continuous; it exists whil ...

Loop Quantum Cosmology (LQC) applies the non-perturbative techniques of loop quantum gravity to homogeneous cosmological models, yielding a quantum replacement of the classical big-bang singularity by ...

Quantum gravity seeks a unified framework reconciling general relativity’s description of spacetime with quantum mechanics. Leading approaches include loop quantum gravity, spin-foam models and group ...

Physicists have put a decades-old idea about why the strange rules of quantum mechanics disappear in our everyday world to one of its toughest experimental tests yet. Deep beneath Italy’s Gran Sasso ...

A proposed model unites quantum theory with classical gravity by assuming that states evolve in a probabilistic way, like a game of chance. Physicists’ best theory of matter is quantum mechanics, ...

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

This week, physicists at University College London announced – in 2 papers published simultaneously – a radical new theory that consistently unifies Einstein’s gravity and quantum mechanics while ...
