  1. “Entropic gravity, also known as emergent gravity, is a theory in modern physics that describes gravity as an entropic force—a force with macro-scale homogeneity but which is subject to quantum-level disorder—and not a fundamental interaction. The theory, based on string theory, black hole physics, and quantum information theory, describes gravity as an emergent phenomenon that springs from the quantum entanglement of small bits of spacetime information”.

    There is an interesting review about Emergent Gravity in following article:

    “This is also often referred to as a “holographic” entropy because it demonstrates that all what happens inside the volume can entirely be encoded on its surface. The additional entropy that Verlinde introduces instead grows with the volume itself”.
