A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...
Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...
Spacecrafts don’t just rely on rockets—they use planets to pick up speed! Spacecrafts don’t just rely on rockets—they use planets to pick up speed! It’s called a gravity assist, and it’s one of the ...
A new study by researchers from the University of Barcelona and the University of Padua challenges one of the core ideas of modern cosmology: that the Universe began with a rapid expansion called ...
