Entropic Gravity?

with one comment

The physics world is abuzz with excitement over Eric Verlinde’s  Entropic Gravity Paper.  It suggests that differences in entropy between parts of the universe generates a force that redistributes matter in a way that maximises entropy. This is the force we call gravity. Many other papers are now coming out with similar ideas, including one that relates gravity to quantum information for the first time.  A brief summary here and a more detailed description of how entropic forces arise here

So is gravity a side effect of information? I think its a very intriguing idea, a new way to look at our fundamental forces. It’ll be interesting to watch as this gets critiqued and verified over the years.
