Abstract: | Erik Verlinde recently proposed an idea about the thermodynamic origin ofgravity. Though this is a beautiful idea, which may resolve many longstanding problems in the theories of gravity, it also raises many otherproblems. In this article I will comment on some of the problems ofVerlinde's proposal with special emphasis on the thermodynamical originof the principle of relativity. It is found that there is a large group of hiddensymmetries of thermodynamics, which contains the Poincare group of thespacetime for which space is emergent. This explains the thermodynamicorigin of the principle of relativity. |
