Last month, a lot of newspapers and websites have been promoting this article on Nature referring to a recent preprint uploaded by Stephen W. Hawking to the internet repository ArXiv. In this work, summarizing what he talked about in […]

One of hottest topics in theoretical physics today is, of course, quantum gravity. The fact that, almost a hundred years after the born of the quantum theory, we still not have a functional theory that describes gravity at a microscopic […]

During the last year, a longtime forgotten controversy was reactivated by a very interesting paper written by J. Polchinski and his collaborators, in which they questioned whether the so called black hole complementarity principle is a good solution to […]

Quantum field theory has been the paradigm of modern physics since it was formulated in the first half of the last century. It is based on the idea that everything in physics corresponds to the interaction of some fundamental fields […]

Where is the half of the ordinary matter in the universe not observed yet? Computer simulations of cosmological galaxy formation predict the existence of large intercluster filaments of hot and low-density gas, the so-called cosmic web. For the first time, […]
