What is mass?

Mass is an invention of our human minds!
Welcome to this page of the Gravimotion Web Sites Family.
Gravimotion is a new interpretation of Nature, an aternate to theoretical physics.

Neither a writer nor a physicist, the author of this essay follows its own imagination.

Introduction

There is a good reason for which our human mental concept of mass does not exist in reality.
This good reason is explained in details in this very website, just click: explain why there is no mass in matter.

In the following, Einstein's E = mC2 famous equation is used to show that Nature, very likely favors that scenario that mass doesn't exist in reality!
Einstein's equation can be interpreted in 2 different ways, providing 2 opposite interpretations of mass and energy!

According to physics, mass is energy

The speed of light C in vacuum is in physics a universal constant.
As such selecting an appropriate unit system, C can be chosen as C=1.
Now C2=1 and the equation is reduced to (mass) m = E (energy).
Mass is energy! And this led to the discovery that mass is atomic energy.
Please note that making C2=1 does not suppress the reality of light energy.
Worse Einstein's equation is now limping out of balance! How could inert mass and energy make one?

Here is a different logic, and along with it different concepts of mass and energy

Identifying mass to energy doesn't make sense.
Inertial mass very essence, in physics, is to impede acceleration.
As such mass physically inert is the opposite of energy. Mass is energy's very anti-entity!

On the other hand, because dynamic, the factor C2 is better adapted at playing the role of energy than mass will ever do.
The following has to be taken in consideration though:
  1. The term C2 should not be considered as representing light energy1.
  2. C in C2 should not be considered as light speed, forbidden in physics, but simply as a speed2.
In the science of physics an electron energy is in its motion... in physics, energy is found in speed.
Getting back then to E = mC2, even though neither expression looks logical at first, it makes more sense to write C2 = E than m = E.
It makes sense because the mathematical speed C is considered here to represent physical thrust3.
Now C2 being labeled energy, and just to keep Einstein's equation balanced, the mass m has to be demoted to a number without units.
All in all energy E is the product of a number m, which we call mass and that has no units by C2 a specific amount of energy: E = m C2.

The alleged mass atomic energy becomes motion atomic energy, just as it manifests itself when liberated!
Matter is energy packaged with energy both made of physical motion, both very likely releasable under the form of motion when appropriate conditions are met.
There is no mass in the atom! Mass is an illusion of our minds!

Conclusion

The dynamic factor C2 is by far better adapted, than the inert mass m, to account for the energy in Einstein's equation.
The side effect of this new interpretation is that mass doesn't exist and is an illusion of our minds!
As a consequence the answer to the question: what is mass? is that mass is only a word of the English language!

At the origin of this interpretation of Einstein famous equation is gravimotion interpretation of Nature.
Actually in gravimotion, both energy and mass are considered to be fictitious and have no physical collateral!
On the other hand while ignored in physics, motion is real in gravimotion's interpretation of Nature.

Footnote 1:
Light energy is either found in the amplitude of the light wave (Maxwell's equations) or in the light wave frequency (physics' photons) and not in light own speed C.
Footnote 2:
In the science of physics light energy comes under the format of speedy photon particles.
While photons have no mass, photons in physics have a frequency that precisely plays the role that mass has in discrete particles such as electrons.
It does so because the relative motions of the emitters and receivers of light, independently of light's intrinsic speed C, do modify the photons frequency or energy, just as relative speeds modify a particle electron mass/kinetic energy.
From that point of view Einstein's factor mC2 looks very much like kinetic energy mv2.

Footnote 3:
Even though not the case in reality, the speed of light C is considered mathematrically to embody energy, just as any speed v does, through its plain characteristic of dynamic speed.
