#### 5th meeting - intro to LQG (02/11/17)

During the fifth meeting Alessandro Iannone and Damiano Zanetti presented a brief introduction to loop quantum gravity (LQG), the purpose was not to give an exhaustive overview on the subject but rather to heuristically introduce the formalism. 504 more words

#### Black and White Hole Twins Connected by Quantum Gravity

*By Javier Olmedo, Sahil Saini and Parampreet Singh*

Black holes are perhaps the most exotic objects in our Universe with very intriguing properties. The event horizon does not allow light and matter to escape, and hides the central singularity. 922 more words

#### Reality Is Not What It Seems: The Journey to Quantum Gravity by Carlo Rovelli
