Uncertainty principle
This site is part of the gravimotion's web sites family.
Gravimotion is a new unheardof interpretation of physics mathematics.
It so happens that gravimotion and the uncertainty principle fit like hand in glove!

The Uncertainty Principle Involves 2 Related Quantities.
If a measurement is exact (which never happens in experiments) the uncertainty of measure is zero.
The uncertainty principle relates the uncertainty of measurement of a position to the uncertainty measurement of a dynamic phenomenon such as speed or momentum.
The uncertainty principle is also relating the measurements uncertainties of time and energy or time and frequency.
Here are a few examples of the dual quantities involved in the uncertainty principle:
 Position and speed
 Position and momentum
 Time and energy
 ... and many more
Introduction to the uncertainty principle
Choosing the first example above, physics' uncertainty principle is as follows:
The product of the uncertainties of measurements of speed and position is equal or greater than Planck's constant, which is a very small number.
In the illustration shown on this page the expression " 0% " stands for "almost equal to zero", the almost being "precisely Planck's constant" (a very small value).
And please note that 100% or 100/100 = 1.
The animated graph illustrates the extremes cases.
 Case 1
 The best physical measure of the speed of an object (almost 0% uncertainty), forbids any measure (100% uncertainty) of its position.
 Case 2
 Conversely the best measure of the position of an object (almost 0% uncertainty) forbids the exact measure and knowledge of its speed (100% uncertainty).
Because Planck's constant is so small, its effect at our scale, let alone at the universe scale, is irrelevant; and for all purposes (at our human scale and larger) a position can be defined with 0% uncertainty that is very precisely.
On the other hand at the atom and subatomic scales, at which the distances are of the order of Planck's constant, the concept of position fades away entirely.
In quantum physics, no matter the speed (or lack of it), the concept of position is no longer absolute.
The uncertainty principle mandates the dismissal of our human concept of position
Consider the reality of the expansion of the universe... the reality is that everything is in motion; everything has a speed.
Merging the expansion of the universe (every thing is moving) with the uncertainty principle (if something is moving that something has no position) abolishes, even at our scale, the concept of position!
Taking in account reality that is the expansion of the universe, our human concept of position is not a physical entity.
And that's not all! The concept of position gone, the reality of motion becomes certainty!
Because everything is in motion along the expansion of the universe:
 There is no position in reality.
 Conversely though, the uncertainty principle mandates that motion is 100% certain that is real!
The combination of physicsuncertaintyprinciple with the realityoftheuniverseexpansion brings certainty right back to our human interpretation (theoretical physics) of Nature!
What is that certainty unveiled by the uncertainty principle?
Motion is certainty.
Certainty is only found in change.
The only thing certain is change or motion.
Gravimotion and the uncertainty principle fit like hand in glove
Gravimotion, which happens to be exclusively based on motion, is in perfect symbiosis with the mathematics of the Uncertainty Principle.
Motion which is certain, is in gravimotion the building block of the universe; in gravimotion's interpretation of Nature, light is pure motion, gravity is pure motion, spacetime is pure motion, even subatomic particles (matter) are made of motion.
In order to focus on the subject and not to divert your attention with yet another controversy, I mentioned the expension of the universe all along this page; for your information though, in gravimotion interpretation of Nature the present is made of movements called the present mo(ve)ment, and gravimotion's present mo(ve)ment replaces and abolished physics expension of the universe.
