Einstein's "Zur Elektrodynamik bewegter Körper", which includes E=mc2, was received in June 30, 1905.
The idea of light quanta were nearly universally rejected by all physicists, including Max Planck and Niels Bohr.
The work remained controversial for many years.
The letter below is to introduce an extra measure added to Einstein's theory of relativity:
an absolute.
Black Holes behind the expansion of the Universe?
Fact or fiction? You decide.
One of the most fundamental questions in science concerning the Universe is: why wasn't matter cancelled
by antimatter at the Big Bang? The following is to find some answers.
1. Primordial Waters.
Before the Beginning there was Timelessness...
Imagine an infinitely large balloon, which size can not be defined, as it is impossible to know where does it start or end.
Nor is it possible to find its center  of infinity  no matter how much Time to spend in searching for it 
the very center of that infinitely large balloon.
If a 'fixed center' of such infinitely large balloon (above left) remains static (immobile), then there is no difference between a
positive or negative time, distance and weight, as from Timelessness (the center) perspective,
the impossibility of having a negative weight, distance
and time, for example, is meaningless, while the impossibility of having simultaneously a negative weight  from positive weight's
perspective  has a meaning.
Therefore, all what's possible and impossible depend on the perspective.
But now, if to imagine that this infinitely large balloon is made of infinite number of smaller balloons, then it would give a chance to
decide, from how big balloons could infinity be made of, which would make it also possible to observe and measure
the sizes of these balloons, and locate their centers, no matter how many of these balloons would make an infinity (above right).
But before making any observations, two fundamental questions should be answered:
Q1: What is Nothing?
It's when a plus one kilogram balloon and a minus one kilogram balloon have exactly the same center (spacetime coordinates),
be it made of (what's potentially to become) hydrogen or antihydrogen, helium or antihelium, carbon or anticarbon, silicon... or any other element.
Q2: How to get Something out of such Nothing?
Firstly, one should have an ability to move relative to X (time) and Y (distance) axes (above right) at zero mass,
and secondly, one should have an ability to overcome the masssymmetry, or gravity.
If these two conditions are met, it is possible to get something out of nothing
via TimeShift, where the plus/minus 'balloons' do not have the same center, or spacetime coordinates.
Such TimeShift sets some strict rules: observations can be made either inside 'Alpha balloon' with the timearrow towards the past,
or 'Omega balloon' with the timearrow towards the antipast or the future, but not in both simultaneously.
Yet, when Alpha is separated from Omega, there is a tension  a natural urge  an instinct to rejoin.
In order to comprehend this, imagine that the center of such infinitely large balloon  of Timelessness  can be at any location.
If to presume that it
can also be simultaneously in different locations, then it would take time to cover a distance between any two possible centers
of Timelessness.
If now to identify one of these potential centers as the Beginning of Time or Alpha, and then locate the other
center as the End of Time or Omega, then it would create a measurable difference of the balloons'
opposite weight (mass). It would not matter anymore how big is infinity, as all that matters is we can now identify and
locate everything between the beginning and the end of infinity.
Yet, there's a dilemma:
the more one knows about his/her location (where you are), the less one knows about his/her true identity (who you are); and vice versa:
the more one knows about his/her true identity, the less one knows about his/her location.
Here's what the (cube) model suggests:
The total mass of the Universe  everything that can be identified and located  equals zero in its opposite value at the moment of Big Bang
(see E=0 below), followed by mass conversion,
or polarity flip, to balance the asymmetry tension between Absolutely Everything and Absolutely Nothing (i.e. 11=0).
Note: the upper and lower corners (X=C and Y=C axes below) correspond to the speed of light,
at a "higher speed" of which, mass has a negative value. (Hourglass by Bruno.)
2. Black and White Snake.
In order to simplify the concept, just 2 opposites  black and white  are explored,
where matter has a positive and antimatter a negative mass.
There are 4 possible instances:
1. Known matter +m (the past);
2. Black Hole (the past present);
[Time Zero Asymmetry Flip (mass (time) reversal)];
3. White Hole (the future present);
4. Unknown (dark) matter m (an 'antipast', or the future).
