Sean on video: "The Origin of the Universe and the Arrow of Time"

Less crazy than I thought - but he doesn't really present or consider alternatives to the "baby universe" hypothesis - which seems to make little sense considering what wild speculation it is.

Possible super-humanly intelligent breakthrough on the problem of gravity and the arrow of time!

'The Entropy Force' (New Scientist)

The Entropy Force

--

Verlinde's work offers an alternative way of looking at the problem. "I am convinced now, gravity is a phenomenon emerging from the fundamental properties of space and time," he says.

To understand what Verlinde is proposing, consider the concept of fluidity in water. Individual molecules have no fluidity, but collectively they do. Similarly, the force of gravity is not something ingrained in matter itself. It is an extra physical effect, emerging from the interplay of mass, time and space, says Verlinde. His idea of gravity as an "entropic force" is based on these first principles of thermodynamics - but works within an exotic description of space-time called holography.
