Did Newton’s Apple Lead Him to the Wrong Conclusion?

  In 2000, a man using the name “John Titor” claimed to be a time traveler from the year 2036.  He described that he was able to achieve this feat by manipulation of gravity in a very specific way.  
    Now, everyone knows the story of how the idea of “gravity” came to Newton by observing an apple fall from a tree.  Isaac Newton’s Principia was published in the early 1600’s and has stood the test of time (so to speak) ever since.  
   What is truly interesting regarding these laws of motion is that they are laws.  They are universally accepted…unquestioned.
   Is it time to revisit these laws that we take for granted?  Are we going to assume that gravity is so simple of a concept with no other aspects to it, that it could be completely described in the 1600’s?  Is there truly nothing left to discover about gravity?
  Turning to John Titor’s machine, let’s assume he was truthful in his description that time travel is done with the manipulation of one of the fundamental forces of the universe: gravity (this universe, at any rate).  As any scientist will tell you,  any number of side effects and ancillary discoveries usually take place in any field of endeavor.  So, naturally, it stands to reason that during the development of the precursor technology that led to time travel (as described in Conviction of a Time Traveler) must have made ancillary discoveries along the way.  You can’t just start monkeying around with the forces of the universe and discover something new that you didn’t know before you started…
  What discoveries were made about gravity itself during the development of the technology?  
  Is it possible that we have a fundamental misunderstanding of gravity itself?  Is it possible that for the last 400 years, we have been operating under a false premise?  Are we only now discovering that Newton, for all of his genius, might have been wrong? 
  Of course, he couldn’t possibly have known the true nature of gravity, if Dr. Verlinde in the below article is correct.  He simply didn’t have the full body of knowledge available to him that our current scientists do.  Nor did he have access to super computers and the rest.  Hell, the man had no knowledge of electricity!  
   Maybe we should allow for the possibility that scientists from the Renaissance might not have had all the answers?

 Many people have heard the story of when Newton sat under an apple tree to think, and suddenly an apple fell on his head and he conceived the theory of gravity. But after a long time, physicists knew gravity was a very strange physical law. Compared to other basic interaction forces, gravity was very difficult to deal with. Now the reasons for this peculiarity may have been explained: gravity is not a fundamental interaction force, but instead may be the derivative of another more fundamental power.
Dr. Eric Verlinde
Professor Eric Verlinde, 48, a respected string theorist and a professor of physics at the Institute of Theoretical Physics at the University of Amsterdam, proposed a new theory of gravity as reported by the New York Times on July 12, 2010. He argued in a paper, titled “On the Origin of Gravity and the Laws of Newton” that gravity is a consequence of the laws of thermodynamics. Reversing the logic of 300 years of science, his contention is that gravity is an illusion that has caused continued turmoil among physicists, or at least among those who profess to understand it.
“For me, gravity doesn’t exist,” said Dr. Verlinde. It’s not that the Apple won’t fall to the ground, but Dr. Verlinde, along with some other physicists, thinks that science has been looking at gravity the wrong way and that there is something more basic from which gravity “emerges,” the way stock markets emerge from the collective behavior of individual investors or how elasticity emerges from the mechanics of atoms.
The core of the theory may be relevant to the lack of order in physical systems. His argument is something you could call the “bad hair day” theory of gravity. It goes like this: your hair frizzles in the heat and humidity because there are more ways for your hair to be curled than to be straight, and nature likes options. So it takes a force to pull hair straight and eliminate nature’s options. Forget curved space or the spooky attraction described by Isaac Newton’s equations. Dr. Verlinde postulates that the force we call gravity is simply a by-product of nature’s propensity to maximize disorder.
Professor Verlinde’s theory is that gravity is essentially an entropic force. An object moving around other small objects will change the disorder surrounding the objects and gravity will be felt. Based on this idea in the Holographic theory, he can derive Newton’s second law of mechanics. In addition, his theory on the physics of inertial mass is also a new understanding. 
Research on the universe in modern science is essentially based on the theory of gravity. If gravity does not exist, then our understanding of the galaxy and the universe’s structure could be wrong. This may be why astronomers often find it difficult to explain gravitational movement’s of distant celestial bodies and have to introduce the concept of “dark matter” to help balance the equations. A new theory of gravity could shed light on some of the vexing cosmic issues that physicists come across, like dark energy, a kind of anti-gravity that seems to be speeding up the expansion of the universe, or the dark matter that is supposedly needed to hold galaxies together. It may stimulate scientists to seek a new understanding of the universe.
“We’ve known for a long time gravity doesn’t exist,” Dr. Verlinde said, “It’s time to yell it.”
