The Michigan nobel laureate Dr. Martinus Veltman who is a great teacher and also a man of great inspiration in high energy physics used to note in the class that quantum gravity has not been found to be renormalizable. If a quantum field theory is not renormalizable, its prediction can not be considered reliable. It basically means that quantum gravity is not a viable physical theory.
There can be several reasons for this. First and the foremost possibility is that gravity may not be a quantum phenomenon after all as I mentioned in the previous pages. Dipole gravity strongly suggests that gravity must be a bulk effect. If gravity is not a quantum phenomenon, any attempts to unify gravity with other forces of the nature will be fruitless.
It may not be a coincidence that quantum gravity hasn't provided a single testable predictions in the atomic level other than the quantum wormhole that no one knows how to create one. Also, I do not understand why quantum worm hole should be relevant to the macroscopic world even if it may exist in some kind of an unknown form.
I think the physics world has been pushed too far into letting believe plausible nonsenses that when the real physical theory came out, no one seems to be able to figure out what the real truth was or has been.
Physics is a discipline where you have to be able to mechanically imagine the situation no matter how complex the system may look like. Without the intuitive mechanical guidance, physics becomes a meta physics where no one knows for sure how the world is exactly operating.
When the quantum wormhole theory came out and the very concept was used as a main theme of a scifi movie, I was wondering if we are being totally detached from the common sense in a massive scale.
The current culture of physics is that if a calculation shows the correct result, with an accuracy of 10^-10 order, that should be enough for the validity of a physical theory that predicts it. It doesn't matter if the theory is mathematically or mechanical intuitively faulty.
The very fact that one has to subtract infinities from the calculation to make sense out of the theory is purely a mathematical nonsense. But for physicist it doesn't matter as far as the result justifies the means.
At this point, one should feel that there must be much more to it than quantum field theory in the world of physics.

Shrunken Degree of Freedom of Motion
Newtonian mechanics has taught us that an extended object in space has six degrees of freedom of motion. That is because there are three spatial degrees of freedom of translational motion and the additional three degrees of freedom of motion by spin rotation. Those six degrees of freedom of motion do not depend on one another within Newtonian mechanics.
Now one can see that dipole gravity tells us that is not exactly the case. An object which has the longitudinal asymmetry like a hemisphere has the degree of freedom of motion gets entangled because the spinning along the symmetry axis causes the voluntary motion along the same axis.
Of course, this happens only when the object is not of spherical or cylindrical shape. One may wonder if this can have any implications on the kinetic theory of gases because some molecules have tetrahedral shape which is longitudinally asymmetric no matter which direction it may want to spin rotate. There have been reports of anomalous behavior on the specific heat coefficient on gaseous states of some of the molecules.
I want to draw attention of the experts in the field onto this phenomenon. We may have an additional proof of dipole gravity in action in the microscopic level. Obviously the universe is not exactly the way we used to think it should be. Instead of six degrees of freedom of motion, we may have only 5.5 degree of freedom of motion. Considering that people are talking about 10 dimensional space according to the string theory, this idea of shrunken degree of freedom of motion may not be too far fetched.
Obviously there are ways to develop a theory in physics by going up the higher order of symmetry into which everyone is involved to get an answer but there are also ways by following the direction of broken symmetry which is the case of dipole gravity. By observing the way how the symmetry is breaking in physics, it can guide us to the answer to many of the unsolved mysteries in the universe.
