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…

Lumber Price Peak Would Raise Concerns For Equities!

The supply chain has dealt with several issues over the past couple of years, as consumers and businesses have been forced to navigate a tricky “COVID” landscape.

Commodity prices (in general) have risen, while enduring some big swings.

Today we look at a commodity that plays an intricate role for consumers, and perhaps the equities market as well. Lumber. When lumber prices are high, new homes and buildings cost quite a bit more.

Above is a “weekly” chart of lumber prices. As you can see, there have been times when a lumber peak/bottom have be...

Bitcoin Swings Down to Support

Courtesy of Read the Ticker

Come on! Seriously do you think a 400% rally for Bitcoin was going to be given to the public easily. Without any pain! Come on muppets!



The uniformed (public) buy when price is rising or breaking new highs, the informed buy when price is falling or breaking lows.



The informed have to do it this way as they are large volume players and the only way they can buy large volume is to create chaos. The chaos brings to the market the weak holders and a forced sell. Price is moved to where the volume can be accumulated, in a bull trend that is down to critical support.



Of course if price is in a true bull market the 'chaos' created should not break critical long term trend signals, ...

On March 23, 2021, a massive ship named Ever Given became lodged in the Suez Canal, completely blocking traffic in both directions. According to the Suez Canal Authority, the 1,312 foot long (400 m) container ship ran aground during a sandstorm that caused low visibility, impacting the ship’s navigation. The vessel is owned by Taiwanese shipping firm, Evergreen Marine.

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
