Wagner Speed
The distance from the Sun to the Earth is shown as 150 million kilometers, an approximate average.
Sunlight takes about 8 minutes 19 seconds to reach the Earth (based on the average distance).
Exact values

Wagner speed, denoted by k, is the closest possible speed to lightspeed that could still possibly be distinguished within a 299,792,458 meter span. Its value is one Planck length per second slower than lightspeed (299,792,458 metres per second). It is fastest possible speed possible by mass (without using infinite energy), and aids in theoretical discussion about the speed infinitely close to the speed of light, without reaching it.

 k=c-(L/s)\approx 299792457.99999999999999999999999999999999998383801 m/s


There are speeds faster than Wagner speed, but slower than lightspeed. These speeds would not be measurable in some distance spans because if the particles start at the same point and finish within a Planck length apart, there wold be no possible way to to determine than difference between them. However, if this test were to take place over many lightyears, speeds would be distinguishable between each other because the distance between particles would increase over time. The method of determining the closest possible speed to lightspeed within a given length is the Wagner factor.


The Wagner factor, denoted x is a variable that can be used to find the "max speed" by being placed in the modified equation:

 k_x=\frac{xcs-L}{xs}

and the functional distance by the equation:

 d_x=xcs

where

c\! is the speed of light in a vacuum (299,792,458 metres per second);
L\! is the Planck length (1.616199×10^−35 metres) ;
x\! is the Wagner factor.


These equations can be used to determine any second fastest possible speed within a distance, behind lightspeed. This increases the distance traveled in the numerator, while also lengthening the amount of time in the denominator, resulting in a speed closer to, but still under lightspeed. The Wagner factor is simply the amount of lightseconds the experiment will take place over. For example, a Wagner factor of 1 would occur over 299,792,458 meters (one lightsecond) and a Wagner factor of 2 takes place over 599,584,916 meters (two lightseconds).

Since the Wagner factor modifies the speed, to write a the fastest speed within a 2 lightsecond span, you would write kx=2 . The speed can further be simplified verbally by saying it has a speed of two wags.

 k_{x=2}=\frac{2cs-L}{2s}

The term was coined by Michael Wagner and Matthew Orzechowski on June 8th, 2012 during a physics thought experiment trying to establish an absolute speed of zero. They chose the letter k because it is infinitely close to c without being it (a refrence to the basis of the concept).The Wagner speed is just a more convenient way of talking about the theoretical fastest measurable speed of mass without getting confused with the speed of light.
