What if gravity is just an illusion?"
Maybe gravity as a function and not a cause is about to go mainstream?
http://www.sciencealert.com/a-new-paper ... ally-wrongA theoretical physicist has come up with a new hypothesis that could finally explain the mystery of dark matter - the elusive matter that's predicted to make up around 27 percent of the observable Universe.
According to the new paper, all we have to do to explain the weird effects of dark matter in the Universe is take gravity out of the equation.
"Our current ideas about space, time, and gravity urgently need to be re-thought. We have long known that Einstein's theory of gravity can not work with quantum mechanics", the author the new paper, Erik Verlinde from the University of Amsterdam, told Dutch news site NOS.

Physicists predict that dark matter makes up around 27 percent of all the mass and energy in the observable Universe - in fact, if galaxies didn't have dark matter, gravity alone wouldn't be enough to hold them together - but no one has been able to figure out what it is as yet.

So Verlinde decided to look at the problem another way. If we only proposed dark matter to make up for an inconsistency with gravity, then maybe the issue isn't dark matter at all - maybe the problem is that we don't really understand how gravity works.
[...]
His suggestion is that gravity isn't a fundamental force of nature at all, but rather an emergent phenomenon - just like temperature is an emergent phenomenon that arises from the movement of microscopic particles.
In other words, gravity is a side effect, not the cause, of what's happening in the Universe.
