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…

Norway Desperately Needs Large Oil Discoveries

Authored by Tsvetana Paraskova via OilPrice.com,

Thanks to cost-cuts and large oil discoveries made before the oil price crash, Norway will be able to sustain its oil and gas production over the next five years. But reduced exploration drilling and lack of big discoveries in the past two years spell trouble for Western Europe’s biggest oil and gas producer after 2023, authorities fear.

Nearly two-thirds of the undiscovered resources are thought to be located in the Baren...

Weekly Market Recap Jan 14, 2017

Courtesy of Blain.

After 3 days of mild “rest” – and the first down day of the year (!!) for the S&P 500, bulls came back with bells on Thursday and Friday, driving indexes to record highs yet again.  This is starting to get “parabolic”… some shades of the type of things we saw in 1999.  (See the S&P 500 and NASDAQ charts below)  The S&P 500 gained 1.6% and the NASDAQ 1.7% for the week.

“This reminds me of January 2000,” said Kent Engelke, chief economic strategist, at Capitol Securities Management, which manages $4 billion in assets, referring to the nearly unceasing climb to records for stocks and the unease it can inspire.  “It’s scary, the unrelenting advance,” he added.
