Quantum cosmology and loop quantum gravity constitute two intertwined pillars in the quest for a quantum theory of gravity. Quantum cosmology applies the principles of quantum mechanics to the entire ...

What Planck saw: does the cosmic microwave background harbour evidence for loop quantum cosmology? (Courtesy: ESA and the Planck Collaboration) A theory of quantum gravity that describes the universe ...

Theory of loop quantum cosmology describes how tiny primordial features account for anomalies at the largest scales of the universe While Einstein's theory of general relativity can explain a large ...

A theory that unites quantum mechanics and general relativity claims that there was no first moment in time, but it still agrees with the predictions of classical cosmology. It's in the stars One of ...

How did the universe start? Did we begin with a big bang, or was there a bounce? Might the cosmos evolve in a cycle of expansion and collapse, over and over for all eternity? Now, in two papers, ...

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ongoing quest for quantum gravity. These findings, which involve the behavior ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

Figuring out what was happening right at the moment the Big Bang occurred is a driving quest in cosmology. This search is also linked with the work of physicists to unite the forces, because, although ...

A new study using the theory of quantum loop cosmology accounts for two major mysteries about the large-scale structure of our universe. While Einstein's theory of general relativity can explain a ...
