Gravity is something all of us are familiar with from our first childhood experiences. You drop something – it falls. And the way physicists have described gravity has also been pretty consistent – it’s considered one of the four main forces or “interactions” of nature and how it works has been described by Albert Einstein’s general theory of relativity all the way back in 1915.
But Professor Erik Verlinde, an expert in string theory from the University of Amsterdam and the Delta Institute of Theoretical Physics, thinks that gravity is not a fundamental force of nature because it’s not always there.
Instead it’s “emergent” – coming into existence from changes in microscopic bits of information in the structure of spacetime.
Verlinde first articulated this groundbreaking theory in his 2010 paper, which took on the laws of Newton and argued that gravity is “an entropic force caused by changes in the information associated with the positions of material bodies”. He famously stated then that “gravity is an illusion,” elaborating further that:
“Well, of course gravity is not an illusion in the sense that we know that things fall. Most people, certainly in physics, think we can describe gravity perfectly adequately using Einstein’s General Relativity. But it now seems that we can also start from a microscopic formulation where there is no gravity to begin with, but you can derive it. This is called ‘emergence’.
What’s more, the Dutch professor now published an elaboration of his previous work in “Emergent Gravity and the Dark Universe”, which argues there’s no “dark matter” – a mysterious kind of matter that along with dark energy theoretically makes up 95% of the universe, but has not really been discovered yet. Dark matter alone is thought to account for nearly 27% of the universe’s mass-energy.
There has undoubtedly been something scientifically disconcerting about giving so much significance to a force that’s never been detected directly. It’s existence has only been inferred through gravitational effects. Interestingly, it’s existence has been first suggested by another Dutch scientist – the astronomer Jacobus Kapteyn in 1922.
One way the existence of dark matter was used was to explain why stars in outer regions of space seem to rotate faster around the center of their galaxy than theory suggested. What Verlinde proposes is that gravity just works differently from how we previously understood it, and creating the concept of dark matter is irrelevant. He is able to predict the velocity of outer-rim stars and their “excess gravity” within his new theory.
“We have evidence that this new view of gravity actually agrees with the observations,” said Verlinde. “At large scales, it seems, gravity just doesn’t behave the way Einstein’s theory predicts.”
This aspect of Verlinde’s theory was actually tested recently with success by a team of Dutch scientists. One great outcome of Verlinde’s work is that it pushes us further towards reconciling quantum physics with general relativity.
“Many theoretical physicists like me are working on a revision of the theory, and some major advancements have been made. We might be standing on the brink of a new scientific revolution that will radically change our views on the very nature of space, time and gravity, “ explained Verlinde.

Click here for commentsBefore the "universe" (which does not exist, but "epistemologically different worlds" exist), it was an EW that did not exist for our "universe". I wrote this in 2007 in one of my papers. See FIVE books FREE (and many papers) at my webpage. Dark matter and dark energy, space and time do not exist. However, there has to be something: “Nothing” in our world corresponds to “something” that belongs to an “epistemologically different world”. Last year, I explained the “relationship” of dark matter connecting two galaxies.
ReplyOn this topic see on Amazon: “(2016) DARK MATTER AND DARK ENERGY, SPACE AND TIME, AND OTHER PSEUDO-NOTIONS IN COSMOLOGY” by Gabriel Vacariu (Author), Mihai Vacariu (Author) (also my 5 books FREE (in English) at my webpage http://filosofie.unibuc.ro/cv_gabriel_vacariu/)
See FIVE books FREE at my webpage: in my works, I showed that quantum mechanics is wrong. Also, I indicated the ontology of special and general relativity and with my EDWs perspective, Einstein won his fight against quantum physicists! Also, in 2015, I showed that space and time do not even exist.
ReplySee at SPRINGER (Germany): (2016) ILLUSIONS OF HUMAN THINKING: ON CONCEPTS OF MIND, REALITY, AND UNIVERSE IN PSYCHOLOGY, NEUROSCIENCE, AND PHYSICS, Author: Vacariu, Gabriel. Written by Springer staff:
• “The Book delivers a new axiomatic-hyperontological framework for a non-contradictory conceptual understanding of ‘Welt’ (‘Universe’)
• Shows how to solve fundamental and philosophical problems of Science (‘Pseudoproblems’)
• Gives deep insight into philosophical discussions of Philosophy of Mind, Neurosciences, Psychology, Theory of Relativity, Quantum Mechanics.
The book illustrates that the traditional philosophical concept of the ‘Universe’, the ‘World’ has led to anomalies and paradoxes in the realm of knowledge. The author replaces this notion by the EDWs perspective, i.e. a new axiomatic hyperontological framework of ‘Epistemologically Different Worlds’ (EDWs). Thus it becomes possible to find a more appropriate approach to different branches of science, such as cognitive neuroscience, physics, biology and the philosophy of mind. The consequences are a better understanding of the mind-body problem, quantum physics non-locality or entanglement, the measurement problem, Einstein’s theory of relativity and the binding problem in cognitive neuroscience.” (here: https://www.springer.com/gp/book/9783658104436)
In this book: the new approach regarding quantum problems, the mind-brain problem, the micro-macro problem - reality, “world”, “universe” does not even exist. Something else exist, but for what really exist, the “Epistemologically Different Worlds”. This book is a summary of the main ideas of my books published in 2008, 2010, 2011, 2012, and 2014 and posted at my webpage (and other pages) FREE.
• At my webpage http://filosofie.unibuc.ro/cv_gabriel_vacariu/ (Philosophy, University of Bucharest), see my article 2005 Synthese (USA) (several papers 2002-2003 on the same topic)+ five books FREE each posted on Internet when it was published) on Cognitive (Neuro)science, Physics (quantum theory and Einstein’s relativity), Philosophy (of mind), etc.
• On Amazon, two books: Dark matter and dark energy, space and time, and other pseudo-notions in cosmology (2016) + Is cognitive neuroscience a pseudoscience (2015)
• In book 2014 or 2016, see the ONTOLOGY of Einstein’s special and general theory of relativity within the EDWs perspective!

The increase in corruption, narrow mindedness, incompetency, delusion, misrepresentations, and lies in the business that is modern physics:
ReplyThe argument that everything is, and should be, a creation of thought is madness and stupidity. Ultimately, it will prove fatal. Dream experience is not a creation of thought. TV is a creation of thought. It is a very great truth/fact that the ability of thought to describe OR reconfigure sensory experience is ultimately dependent upon the extent to which thought is similar to sensory experience. Moreover, it is a very great truth/fact that the self represents, forms, and experiences a comprehensive approximation of experience in general by combining conscious and unconscious experience. Think about this very carefully. This is super important.
Enormous amounts of money are made in conjunction with changing experience from what was natural. If we walk away from reality, reality walks away from us. Less explains less, AND more explains more in physics. Get the picture ? Indeed, do you thoughtlessly believe in (or subscribe to) what has increasingly become the new TV land fantasy "physics" ? Math is everything in physics; really ??!! String theory is garbage. All of this has "control freaks/idiots" written all over it.
What does it take to be the real/true and the legitimate leader in physics ? The integrated extensiveness of thought (and description) is improved in the truly superior mind. This is true top down thinking which includes and involves common sense. Reality, nature/natural experience, AND truth go hand in hand. Balance and completeness go hand in hand. The balance of being AND experience is essential. Importantly, mathematics involves relatively narrow thinking.
The truth is simple AND important; AND the best explanation is the simplest explanation. Indeed, keep it simple; keep it real. The academic "physicists" do not do top down thinking in physics. I do. It shows. I deal in and with real physics/physical experience. People who cannot handle the truth cannot handle reality. People who cannot handle reality cannot handle the truth. Think !!!
The truth regarding physics/physical experience matters. In fact, it is super important; especially these days.
