Abstract- This article is to present viable argument against Albert Einstein’s paper of June 30, 1905 titled ”On the electrodynamics of a moving body” and the mentioning definition of simultaneity which is also a part of Albert Einstein’s theory of relativity of 1915.

**Section One- Defining**

**Part One – Defining Simultaneity. **

Firstly, we must be certain in our minds that we understand the definition of simultaneity. Albert Einstein defined simultaneity as the property of two events happening simultaneously in a reference frame, however according to Einstein’s theory of relativity , this is not a value or principle which is regarded as universally valid or which may be viewed without relation to other things, something that is simultaneous in one reference frame is not necessarily simultaneous in another reference frame . Simultaneity is also closely related to time dilation, Albert Einstein’s 1905 paper of special relativity and many experiments showing that time slows down relative to velocity.

**Part Two – Defining Simultaneous.**

To be certain, for us to reach an understanding, it is an important value to be sure that our definitions use are understood. Simultaneous, is events that happen at the exact same time, a synchronisation. For example, if two different people were both born at exactly 3.30 am on Monday January 1st 2016, these two independent events would be simultaneous events happening at the exact same time.

**Part Three – Defining Time. **

It is important in the understanding of simultaneity and simultaneous to completely understand time and to build a central or primary rule or principle on which time is based. Time is the rudiment of existence, time is said to have begun of the big bang some what fourteen billion years ago. Time is said to be the thing that stops things happening all at once. Presently we refer to time as a measurement, the movement of the hands of a clock or the present use of Caesium clocks and it is said that the integral of the frequency is time, 9,192,631,770 hertz being equal to one second of time measurement. In ordinary terms , time is the mechanism that allows us to synchronise our everyday lives, synchronised in respect relative to the inertial reference frame of the gravitational constant of the Earth and relative velocity, but not simultaneous relative to other reference frames according to relativity.

**Part Four – Defining Measurement.**

To continue in the aim of understanding, let us define what a measurement is and be certain that we understand. A measurement is the distance between two geometrical points. A base quantity such as a length of a distance or such as an increment length of time or the mass of something. Measurement is a scalar quantity when spoken in these terms, often based on linearities between two points and the result of measurement being a finite result contained between two points. Measurement generally uses a first point with a zero value and the second point being the result of the measurement. This scalar type measurement differs slightly to the measuring system of vector measurement. Vector measurement concerns with velocities added and several geometrical points and uses Minkowski’s space-time, a four dimension manifold of three dimensions of X,Y,Z and a forth dimension of time, also used in Albert Einstein’s special relativity and the common use of present.

**Part Five – Defining Constant.**

It is worldly accepted that the speed of light is constant to all observers in any reference frame when measured in a vacuum. When talking Physics, the word constant refers to the speed of light and means that the speed of light is unchanging and can be measured to being the same speed by any observer. However, the speed of light is not infinite but is widely agreed to be finite. To be clear on our understanding, the constant of light is only constant and unchanged in a vacuum, where as none vacuums with mediums and objects have effect and makes the speed a variate and changing wavelength. However it is of importance that we understand the word constant has other meanings.

Let us consider colour, relative to us we observe colour , colours are a wave-length of light, a certain frequency that defines the colour we observe. In observation we observe a red apple, the colour of red is constant to all visual observers who are not colour blind. The red is unchanging and remains a constant until it decays and loses it’s colour.

Let us now consider gravity, relative to us it is constantly pulling us to the ground.

So in our understanding constant is more than just a constant speed, it is any observation occurring continuously over a period of time.

**Section Two – Understanding**

**Part One – Understanding the constant-‘constant of light propagating through space.**

Light in a vacuum travels at 299 792 458 m / s and is a constant. Space is a near perfect vacuum and is ”transparent” to light, meaning that space allows light to propagate through space unchanging in the constant speed. Ourselves, observe a clarity of space in that relatively we can observe distant objects reflecting light and the space between ourselves and the observed object is not opaque, it is relatively ”see through”. This observation is relatively constant to all visual observers in any frame of reference that is not in shadow/night.

**Part Two-Understanding the relative velocity of light relative to a bodies geometric position and relative simultaneity time frame according to present information.**

Light is a finite constant speed and takes a period of time to reach it’s destination. Essentially when we observe an object in the distant Universe, we are observing that object in a relative geometrical location position where it was (the objects past) .

Let us take two vectors and call them X and Y and let us define two bodies, (A) and (B).

We shall define that body (A) is travelling vector X and emitting light on a path linearity vector Y in the direction of observer (B)

Let us define the time it takes for a Photon (v=c) to travel the distance (d) to (B) of the linearity of (Y) 8 minutes (t=8min)

Let us define that (A) is travelling the vector (X) at momentum (p) and will travel a distance equal to t=8mins while the Photon of (A) travels it’s journey of the Y axis linearity.

In our understanding of this if you were to view a distance object i.e the Sun, the light takes 8 minutes before it reaches your eyes, so it is said that relative to this, we are seeing the body we are observing in the objects past. In the Sun example we see the Sun relative to 8 minutes later .

**Part Three- Understanding Time Dilation**

Time dilation is a change in the rate of time, time is said to be a variate and time dilation being a part of relativity that has been experimentally proven to exist. Hafele-Keating , in October 1971, produced and did an experiment that proved Einstein’s thought’s and relativity to be precise and correct. The experiment consisted of four caesium clocks, the four clocks were flown around the world twice and the conclusive results showed that the rate of time changed relative to velocity of the Caesium clocks. This fundamental change being the evidence that confirms simultaneity .

To be continued……

to be continued..

It is impossibly difficult for us thinking humans to step outside the box of universal time.

Every moment of our lives from birth to death is timed and dated.

Our working lives are governed by the absolute ticks of the clock.

We are not made of light nor do we travel at fantastic speeds and we spend our time on planet earth.

The curious thing is that even scientific measurements and discoveries are measured by time and in time as if time were very important. We are told the big bang occured 14.6 billion years ago.

Half lives of radio active elements are given precisely down to nano seconds.

Evolution is documented in millions of years; carbon dating which we are told is due to the accurate rate of decay of radio active carbon is relied apon.

Yet we are in the middle of the Hubble explosion with receeding galaxies.

To be honest, its a hard nut to swallow for the untrained layman.

Indeed it is hard to understand, but at the moment it is not finished, maybe you will understand when it is complete.
