Beyond Relativity

Einstein's Relativity Theory proposes that the speed of light always remains constant, but one question has always remained unanswered:

"Velocity relative to what?"

Relativity also proposes time dilations related to velocity. Again the question remains unanswered:

"Velocity relative to what?"
"Velocity relative to what?"

Generally a local datum is selected for analysis, such as the surface of a planet.  In deep space, the selection of a datum becomes problematic. Einstein's Relativety Theory does not address "how", or more importantly "why" a datum is selected. 

Einstein's Relativity Theory is also based on an assumption that the rate of nuclear decay, as used in atomic clocks, never varies and defines absolute time. There is no consideration of time as an independent variable separate from the nuclear decay rate.

Observations of atomic clocks do indeed show that time, as measured by the nuclear decay rate, does infact vary with velocity.  Key questions that arise from this are "why does the decay rate vary?" and "what does this tell us about the importance of the datum?"

The explanation developed by Subtle Atomics to redefine Einstein's Relativity Theory and time dilation observations, is that variations in the rate of nuclear decay are directly related to background energy conditions, including background energy density and the rate of background energy flux compared to the observer.

Based on this, nuclear decay rates are expected to vary due to variations in local conditions such as background energy shielding from large massive objects (local gravity), and movement relative to the local background energy flux direction (velocity relative to large massive objects).  This is consistent with observations of atomic clock time dilations.
Einstein's Relativity: 

"Time Slows as Velocity Increases" 
Subtle Atomics physics redefines relativity as:

Background Energy Based Physics:

"Nuclear Decay Rate is Affected by Background Energy Density and Flux"

Method: Two light particles travelling at the speed of light in opposite directions cross paths.  

Observations:  The first particle says to the second "Hey, you're going twice as fast as the speed of light relative to me, so according to relativity, you're impossible!!!"  The second particle replies: "No, your the one going twice as fast of the speed of light, you're impossible".

Conclusion: A restriction to maximum velocity only makes sense in the context of a background conditions that materially defines a "zero velocity" condition.

A closer examination of Einstein's original paper on relativity shows that a conclusion of Lorentz on the Michelson-Morley experiment, i.e. ​​​​"the speed of light [on earth] was constant", were incorrectly transposed by Einstein as, "the speed of light was ALWAYS constant", (Bourgoin, 2015 & 2016). 

This one led error lead directly to the Theory of Relativity.  

So when does the speed of light to vary? 

We already know that atmospheric density alters the speed of light.  Similarly variations in background energy are also expected to alter the speed of light.  Our nearest neighbour star, Alpha Centauri, at approx. 4.2 light years away, might not actually be as far away as we thought!!!
