Erik Verlinde, the Big Bang and a new Explanation of the Universe
The Japanese translation by me:
Erik Verlinde, the Big Bang and a new Explanation of the Universe (in Japanese)
28 Apr. 2011 Dr. E. Verlinde gave a Lecture at CERN Colloquium. In 2010 He proposed that the string duality and the holographic principle are given by the adiabatic theorem of thermodynamics at Harvard Lecture and at KITP. And I think that Dark matter, Dark energy and Matter are considered from the this point of views. For general audience the above interview article is closely related to the Lecture at CERN.

At Uppsala in the end of Verlinde's lecture someone asked him "How about graviton?"
ReplyDeleteVerlinde answered at once clearly "it is phonon."
I have looked at the both lecture at Strings 2011 and at Perimeter inst. by E. Verlinde.
ReplyDeletePerhaps, about basic part the following item are important:
1, the collapse to black holes (degenerates of fermions) = the gravitational collapse, which is described by the degenerates of matrix in the hidden phase space.
2, the adiabatic theorem (the invariance of the volume in the hidden phase space) reveal gravity as reaction of entropic force. Its quantum dynamics version is Born-Oppenheimer principle.
3, He use the degenerates of matrix to explain dark matter and dark energy.
These basic part are applied to the cosmology. I think:
1, the equilibrium state might correspond to dark energy and the non-equilibrium state to matter. This is the results of the above 1, 2 and 3.
2, The essence of dark energy and dark matter might be related to the equilibrium of the universe. And if they would be true the rotation puzzle of the galaxies would be resolved as like MOND and the value a_0 would be shown from his theory.
Now, I will prepare to an article along the above comments.
ReplyDeleteMr. Marcus commented to the head of the article on String 2011 on blog of Mr. Woit, which is a similar impression as me. (I Notice now.)

The talk that Verlinde is scheduled to give later this week at Uppsala has the same title as one he gave last week (22 June) at Perimeter. Anyone interested can watch the Perimeter video of the talk, which got some lively reactions from the audience.

The Hidden Phase Space of our Universe
Erik Verlinde
By combining insights from black holes and string theory we argue for the existence of a hidden phase space associated with an underlying fast dynamical system, which is largely invisible from a macroscopic point of view. The dynamical system is influenced by slow macroscopic observables, such as positions of objects. This leads to a collection of reaction forces, whose leading order Born Oppenheimer force is determined by the general principle that the phase space volume of the underlying system is preserved. We propose that this adiabatic force is responsible for inertia and gravity. This fact allows us to calculate the hidden phase space volume from the known laws of inertia and gravity. We find that in a cosmological setting the appearance of dark energy is naturally explained by the finite temperature of the underlying system. The adiabatic approximation that leads to the usual laws of inertia and gravity breaks down in the neighborhood of horizons. In this regime the reaction force degenerates into an entropic force, and the laws of inertia and gravity receive corrections due to thermal effects. A simple estimate of these effects leads to the conclusion that they coincide with observed phenomena attributed to dark matter.

On Physics Forums an article titled "CDM/MOND duality through Holography" is related to the argment by E. Verlinde about MOND and entropic gravity theory.
