Lately I’ve seen a several papers describing how one fundamental way of measuring the universe or another is actually emergent from a different way of looking at things. There are those that claim time does not exist in any fundamental way, we are just looking at things wrong. So what is fundamental?
Understand entropy and gravity emerges. Understand it in a moving frame and General Relativity emerges. The idea is published on arxiv (On the Origin of Gravity and the Laws of Newton, Erik Verlinde) and even made it to Slashdot. Woit surveys other entropy related ideas.
As a computer scientist there is something appealing in the notion that information is fundamental and that all the laws of nature are derived from the way information works.
Update: There is a long post from Verlinde on Motl’s blog here. It illuminates some of his ideas and explains their history. If you can stomach Motl’s bullying read the comments too, there are many.
