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…

Don't expect a second round of stimulus checks in June

By Michelle Jones. Originally published at ValueWalk.

Lawmakers from both parties are finally starting to agree that a second round of coronavirus stimulus checks may be needed. However, they are still a long way from making a final decision that will actually result in another round of checks for everyone. Here’s the current status on a second round of stimulus checks.

Tech Indicator Suggesting A Historic Top Could Be Forming?

Courtesy of Chris Kimble

Tech stocks have been the clear leader of the stock market recovery rally, this year and since the lows back in 2007!

But within the ranks of leadership, and an important ratio may be sending a caution message to investors.

In today’s chart, we look at the ratio of large-cap tech stocks (the Nasdaq 100 Index) to the broader tech market (the Nasdaq Composite) on a “monthly” basis.

The large-cap concentrated Nasdaq 100 (only 100 stocks) has been the clear leader for several years versus the ...

M2 Velocity Collapses - Could A Bottom In Capital Velocity Be Setting Up?

Courtesy of Technical Traders

M2 Velocity is the measurement of capital circulating within the economy.  The faster capital circulates within the economy, the more that capital is being deployed within the economy to create output and opportunities for economic growth.  When M2 Velocity contracts, capital is being deployed in investments or assets that prevent that capital from further circulation within the economy – thus preventing further output and opportunity growth features.

The decline in M2 Velocity over the past 10+ years has been dramatic and consistent with the dramatic new zero US Federal Reserve interest rates initiated since just after the 2008 credit crisis market colla...

US Southern States COVID19 Cases – Let’s Give Credit Where Due

The number of new COVID 19 cases has been falling in the Northeast, but the South is not having the same experience. The number of new cases per day in each Southern state has been rangebound for the past month.

And that’s assuming that the numbers haven’t been manipulated. We know that in Georgia’s case at least, they have been. And there are suspicions about Florida as well, as the State now engages in a smear campaign against the fired employee who built its much praised COVID19 database and dashboar...
