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…

Latvia Bank Crisis: Central Bank In Chaos As ECB Blocks Payments By Third Largest Bank

One day after we reported that Latvia's central bank governor - and ECB Governing Council member - Ilmars Rimsevics was detained by Latvia’s anti-corruption authority on Saturday on suspicion of accepting a bribe of more than €100,000, prompting both Latvia's Prime Minister and the president to call on Rimsevics to resign, Latvia now appears to have a full-blown banking crisis on its hands, after the European Central Bank froze all ...

Weekly Market Recap Feb 18, 2017

Courtesy of Blain.

BOO YAH! Now that’s more like it!  Your regularly scheduled non stop up market returned this past week with a “5 for 5” week (all 5 days up).  Three of those days were >1% so it was a return of the bulls.  That said to return to the “Trump market” we need to get back to almost no volatility and incremental up days of 0.3% or so 80% of the time.   We noted in last week’s recap the NYSE McClellan Oscillator was still VERY oversold so a “snapback rally” was still on the docket.  That was quite a snapback rally!  So the “easy part” of the bounce just happened – now we will see if we are going to return to a more volatile future or go right back to the sleepy market that tacks on a little 4 out of 5 ...

The tricks propagandists use to beat science

Via Jean-Luc

How propagandist beat science – they did it for the tobacco industry and now it's in favor of the energy companies:

The tricks propagandists use to beat science

The original tobacco strategy involved several lines of attack. One of these was to fund research that supported the industry and then publish only the results that fit the required narrative. “For instance, in 1954 the TIRC distributed a pamphlet entitled ‘A Scientific Perspective on the Cigarette Controversy’ to nearly 200,000 doctors, journalists, and policy-makers, in which they emphasized favorable research and questioned results supporting the contrary view,” say Weatherall and co, who call this approach biased production.

A second approach promoted independent research that happened to support ...
