Non so se è il thread giusto, ma non volevo aprirne uno nuovo sulla gravità, quindi posto qui, solo per segnalare una nuova teoria che ha suscitato molto interesse:

On the Origin of Gravity and the Laws of Newton (pdf)

Di
Erik P. Verlinde

Starting from first principles and general assumptions Newton's law of gravitation is shown to arise naturally and unavoidably in a theory in which space is emergent through a holographic scenario. Gravity is explained as an entropic force caused by changes in the information associated with the positions of material bodies. A relativistic generalization of the presented arguments directly leads to the Einstein equations. When space is emergent even Newton's law of inertia needs to be explained. The equivalence principle leads us to conclude that it is actually this law of inertia whose origin is entropic.

Qui in termini meno tecnici dal blog Hammock Physicist:

It From Bit: The Case Of Gravity

If it smells like entropy, and it behaves like entropy, it probably is entropy.

A qualcuno interesserà.
