The illusion of Gravity

 Spacetime, the result of a four-dimensional blending of space and time which consists of three dimensions plus time and where we live, or we think we do. 
Amazingly, in 2007 some theories of physics predicted that one of the three dimensions of space could be an illusion! And all the particles and fields that make up reality move in a two- dimensional realm. And to that theory, it is added that gravity is also part of the illusion as a force that materializes along with the emergence of the third dimension. 
Gravity, is one of the most fundamental aspects of life on Earth, the force that pulls together all matter in the universe.
Erik Verlinde, a string theorist and professor of physics, is the one scientist who is proposing this theory which implies that the number of dimensions in reality could be just a matter of perspective just like temperature, we experience it every day, we feel it, but if we think about it in molecules, there is no notion of temperature. Dr. Verlinde insists that scientist had been looking at gravity the wrong way, and that there ir something more basic from which gravity comes from. 
According to Verlinde, gravity is a microcosmic byproduct of a larger entropic force, which is just an enlarged face of a large field of illusion, and it is not just a direct force acting onto a particular object, but it is the accumulation of macrocosmic influences. 
Nature likes options and all of its intimate workings thrive on diverisity, and the microcosmic elements that build the macrocosm, create a tension that balances in a harmonic way with these entropic forces; when something wants to act againts the spiraling realm of cyclical energies, it takes a higher force to shape through all of the diversity to one unique object.Dr. Verlinde uses the example of frizzing hair to explain this feat; there a more ways and options for a strand of hair to curl than to straight, for this, it is needed a great number of factors and energy for the hair to be pulled straight. 
If this theory is prove true, defying gravity could only be a matter of finding the right frequency of vibrations, finding the path that cuts through all the entropic force.
