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…

Brexit: An 'escape room' with no escape

 

Brexit: An ‘escape room’ with no escape

Brexit is beginning to look a lot like an “escape room” with no exit.

An escape room is an increasingly popular adventure game that requires participants to solve a series of puzzles before they can leave the room and advance into another one with additional riddles.

Brexit now seems to be a riddle that can’t be solved, after U.K. lawmakers voted down Prime Minister Theresa May’...

Is This The Real Reason Why Stocks Are Surging?

Courtesy of Zero Hedge

Wondering why US equity markets are soaring at a pace not seen since the March 2009 lows? Confused by the massive swings higher despite weak macro data, and tumbling earnings expectations?

Well, the answer is simple once again, "it's not the economy, it's the central banks, stupid!"

Q4 2018 saw global stock markets finally wake up to the fact that the world's central banks were withdrawing liquidity and played catch-down to an ugly tightening reality. December's contagion to American stocks was the final straw for the world's elites however  and after the Mnuchin Massacre, it appears the Plunge Protection was ordered back into battle...

The "Average Stock" is Facing a Big Test Here!

Courtesy of Chris Kimble.

The Value Line Geometric Index tends to give investors a good idea of the health of the overall market. It is an equal-weighted index with a broad swath of stocks that gives investors an idea of how the “average stock” is performing.

The Value Line Geometric formed highs in the same area in 1998, 2007, and 2015 (see blue line). In the last two years, the index broke out above that line and held above it until the recent correction.

It is now testing the underside of that price area (now resistance). Bulls will get good news with a breakout ABOVE thi...

Crypto-Bubble: Will Bitcoin Bottom In February Or Has It Already?

The new year has been relatively good for the price of bitcoin after a spectacular collapse of the cryptocurrency bubble in 2018. It’s up notably since the middle of December and traded around the psychological level of $4,000... so is this a sign that the crypto market is about to recover?

Of course, it depends on who you ask, but one analyst discovered a pattern which might point to a bottom next month.

D.E. Shaw Investment Calls For Leadership Change At EQT

By ActivistInsight. Originally published at ValueWalk.

Elliott Management has offered to acquire QEP Resources for approximately $2.1 billion, contending the oil and gas explorer’s turnaround efforts have done little to lift the company’s share price. The company responded and said that a thorough review of the proposition is imperative in order to properly act in the best interests of shareholders, “taking into account the company’s other alternatives and current market conditions.” The news came only a month after Travelport Worldwide agreed to sell itself to Siris Capital Group and Elliott’s private equity arm Evergreen Coast Capital for $4.4 billion in cash and two months after Athenahealth was bought by Veritas and Evergreen for $5.7 bi...

Weekly Market Recap Jan 13, 2019

Courtesy of Blain.

In last week’s recap we asked:  “Has the Fed solved all the market’s problems in 1 speech?”

Thus far the market says yes!  As Guns n Roses preached – all we need is a little “patience”.  Four up days followed by a nominal down day Friday had the market following it’s normal pattern the past nearly 30 years – jumping whenever the Federal Reserve hints (or essentially says outright) it is here for the markets.   And in case you missed it the prior Friday, Chairman Powell came back out Thursday to reiterate the news – so…so… so… patient!

Fed Chairman Jerome Powell reinforced that message Thursday during a discussion at the Economic Club of Washington where he said that the central bank will be “fle...

Why Trump Can't Learn

 

Bill Eddy (lawyer, therapist, author) predicted Trump's failure based on his personality, which was evident years ago. This article, written in 2017, references a prescient article Bill wrote before Trump became president, in July, 2016, 5 Reasons Trump Can’t Learn. ~ Ilene

Today, the scientific community is aghast at the prospect of gene editing to create “designer” humans. Gene editing may be of greater consequence than climate change, or even the consequences of unleashing the energy of the atom.
