Is Gravity an Illusion?

Is Gravity an Illusion?

Bedford and Cavour, having arrived on the Moon, Bedford leaps as he would on Earth and finds that, with the strength Moon's gravity weaker than that of the Earth, he needs to move less violently. From The First Men in the Moon by HG Wells. First published London, 1913.

Erik Verlinde is a 48 year old professor of physics at the University of Amsterdam. Verlinde is a celebrated expert in string theory, that esoteric field of research attempting to move the description of the universe beyond Einstein.  Dennis Overbye has a very interesting article today about Verlinde in The New York Times. 

It is not string theory that has attracted new attention to Verlinde.  In fact, what has some of the physics world talking (and some yawning) involves little rigorous mathematics.  Verlinde has proposed that gravity is not a fundamental force of the universe, as proposed by Newton and Einstein.  He proposes that it is secondary, an illusion if you will, resulting from observations of the effects of laws of thermodynamics.  He sees gravity as a symptom produced by entropy, the form that energy takes as a result of irreversible (ie, naturally occurring) processes which make that energy unavailable to do work.  Many are most familiar with entropy as a measure of disorder.

Verlinde sees entropy as a fundamental parameter and gravity as a dependent variable.  Newton and Einstein saw gravity as a fundamental force of the universe whereby any two objects undergo mutual attraction which increases as the product of their masses and decreases as the square of the distance that separates them.  Verlinde’s suggestions seem to be centered on the idea that our perception of gravity is a prisoner of our view of space.  The Overbye article goes into a number of interesting thought processes relating our traditional physics in three dimensional space to holograms which reduce multidimensional information to two dimensional space without any losses.  One of the ideas was written as follows:

Those exploding black holes (at least in theory — none has ever been observed) lit up a new strangeness of nature. Black holes, in effect, are holograms — like the 3-D images you see on bank cards. All the information about what has been lost inside them is encoded on their surfaces. Physicists have been wondering ever since how this “holographic principle” — that we are all maybe just shadows on a distant wall — applies to the universe and where it came from. 

Verlinde’s ideas have critics who say he is lacking in mathematical rigor.  He does sound more like a science philosopher than a practicing theoretical physicist.  Some might say he should try…

Russell 2000 and Semiconductor New Highs / S&P Breaks

Courtesy of Declan.

The S&P broke higher to confirm a 'bear trap' and also closed at a new all-time high. Volume climbed to register an accumulation day but there were further losses in relative performance and continued losses in the MACD.


The Nasdaq posted a gap-driven 1% gain to bring it ever closer to channel resistance. It hasn't yet tagged resistance but it looks well placed to do so by the end of the week. Technical are all bullish.

Rogue State

How the guardians of nationhood conspire in its destruction.

By George Monbiot, published in the Guardian 18th November 2017 (Brexiters, beware: if the ties that bind us unravel, tyranny may soon follow)

What is this country we are asked to love? This might once have been an easy question to answer. National identity was built around a range of institutions, considered to represent the national interest. Rebellion against them was characterised as treason. But one by one, these institutions have been subverted from within. Look to the top to see treacher...
