Why did Verlinde in his paper suggest that information is a central concept in the emergence of gravity? I mean why information and not something else?

craigi said:I believe the inspiration for it comes from 2 things. Firstly, it is of interest to interpret physical phenomena in terms of information in keeping with the Holographic Principle. Secondly, the equations of gravity have similarities with the equations of thermodynamics.
MTd2 said:I just want to know what Verlinde said about Dark Matter and his theory on the conference.
craigi said:He discusses that here:

so I'll ask the the admin for a reminder function in the forum software which alerts me in ten years or so ;-)craigi said:I recall an interview with Verlinde, where he says that he's trying to develop the idea alone. He draws an analogy with Einstein's work on relativity and is talking about a timescale of decades.

friend said:I don't know why they would choose to concentrate on area as holding information. Information is obtained from probability distributions. And a distribution is taken with respect to a random variable along an axis, right. In other words, information is obtained with respect to the space of some variable; there's no information without space. So you could have information associated with 1D, 2D, 3D, etc.
And if there's no information without a space, does that in itself argue for a minimum or maximum amount of information per length and therefore per area and per volume?

craigi said:The reason area, as opposed to volume, is considered so significant to information content is due to the work of Beckenstein, de Hooft and Susskind.
Try reading the wikipedia articles on the Beckenstein Bound, the Holographic Principle and AdS/CFT correspondence for a starting point.
Verlinde's paper titled "On the origin of gravity and the laws of Newton" proposes a new theory of gravity that suggests it may not be a fundamental force, but rather an emergent phenomenon from the laws of thermodynamics.
Verlinde's main argument is that gravity can be explained as an entropic force, meaning it arises from the tendency of particles to maximize their entropy. He also proposes that the laws of Newton can be derived from this theory of gravity.
Unlike traditional theories of gravity, which posit that it is a fundamental force, Verlinde's theory suggests that gravity is a result of the interactions between particles and their environment. This approach is known as entropic gravity.
Verlinde's theory is still a subject of ongoing research and debate in the scientific community. While it has gained some support and has been able to explain certain phenomena, it has not been proven conclusively.
If Verlinde's theory is proven to be true, it could potentially revolutionize our understanding of gravity and the laws of physics. It could also have implications for our understanding of the universe and how it operates at a fundamental level.
