For several years now scientists have been perplexed by an inability to explain what they observe in the Universe. They see the effects of gravity, but they can’t see enough mass out there to remotely justify it. So they’ve created the theory of “dark matter,” of which there would have to be more than all the matter that can be visualized. By visualizing, I mean “seeing” in every conceivable way using all of the electromagnetic spectra.
Another perplexing thing is the phenomenon of gravity as perceived actually seems denser in some areas and more diffuse in other areas yet can’t be explained by the mass of things observed in those areas of space. So weird.
Then there is the real problem of gravity not working at all in quantum physics. Humm.
More and more theoretical physicists suspect gravity is an illusion. That’s why it doesn’t work in quantum physics (where everything is potential. Waves can become particles when observed which means when consciousness interacts with all that potential). Is that why gravity can’t actually be measured. Is that why it seems to behave differently in different parts of the Universe...why it can’t be melded into the “Grand Unification Theory” of all forces. Those are some of the things to ponder about gravity at any rate.
One of the most outspoken about gravity being an illusion is Erik Verlinde of the University of Amsterdam. He claims dark matter does not exist and that gravity emerges from the changes of fundamental bits of information stored in the structure of spacetime (sounds akin to quantum physics).
Gravity is not an illusion in the sense that we know that things fall," says Verlinde." 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’." www.dailygalaxy.com/...
The new theory, called 'emergent gravity', suggests gravity comes as a side-effect of the entropy of the universe. Entropy is a property of thermodynamics. It's often described as the unusable part of a system (or the waste heat if you will) and while that's sometimes a useful description, a better description involves the amount of information contained within a system. An ordered system (say, marbles evenly spaced in a grid) is easy to describe because the objects have simple relations to each other. On the other hand, a disordered system (marbles randomly scattered) take more information to describe, because there isn’t a simple pattern to them. Basically, the more information it takes to describe a system, the more entropy it has. www.forbes.com/...
Humm. Quantum physics actually does explain everything...except gravity. What gives? Could gravity just be information stored within a system? Could it be just some potential waiting to “emerge” and not something that is constantly there? Is it an illusion?
Verlinde's model uses this connection between thermodynamics (heat, energy and forces) and information through a mathematical method known as the holographic principle. Since the information contained within a region of space depends upon the arrangement of objects within that region, moving the objects can change the entropy within the region. Verlinde demonstrated that this produces an entropic force that acts like gravity. From the basic idea of information entropy, one can derive Einstein's equations of general relativity exactly. www.forbes.com/...
Verlinde bases his illusion of gravity on the “holographic principle” (sounds like the title to an episode of Big Bang Theory). What does Scientific American magazine have to say about this?
A hologram is a two-dimensional object, but when viewed under the correct lighting conditions it produces a fully three-dimensional image. All the information describing the three-dimensional image is in essence encoded in the two-dimensional hologram. Similarly, according to the new physics theories, the entire universe could be a kind of a hologram. www.scientificamerican.com/...
I’ll let Erik speak for himself.
And then there was Nikola Tesla who also believed gravity was an illusion, though his theories about it were never published as he came up with it in his 80’s. I’ll post a couple youtube videos about that. They are pretty deep, but you still might still find them interesting (maybe).
