Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Physicists have long struggled with their goal of making gravity a quantum force. A radical post-quantum approach might solve ...

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 ...

Loop Quantum Cosmology (Big Bounce)The holographic cosmology of Episode 6 treated the three-dimensional depth itself as a shadow of information on a boundary surface. It is a path where space emerges ...

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 ...

In a continuous pursuit to understand the fundamental laws that govern the universe, researchers have ventured deep into the realms of string theory, loop quantum gravity, and quantum geometry. These ...

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 ...

In a development at the intersection of quantum mechanics and general relativity, researchers have made significant strides toward unraveling the mysteries of quantum gravity. This work sheds new ...

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 ...

Researchers suggest that unambiguous signals of quantum gravity could appear in future tabletop experiments with gravitationally interacting objects. Is gravity quantum or classical? This fundamental ...
