Attracting problems: Gravity

Soon we will celebrate 100 years of General Relativity. However we are still far from understanding true nature of gravity. Mainstream theories (LQG, string theory) offer different approaches to describe gravity on microscopic level and arrive at theory of quantum gravity, but none of them is spectacularly successful. For some decades, parallel to efforts of standard quantization of the gravity, we have dealt with rising number of theoretical results claiming that General Relativity might be not fundamental theory but only effective description of true fundamental degrees of freedom. Then one can see gravity as emergent phenomenon, having its source in averaging microscopic properties of some unknown fundamental system. Crucial role here plays nontrivial connection between thermodynamics and gravity, which can serve as a hint in our further research.
