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 Universe is: why wasn't matter cancelled
by antimatter moments after 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 'balloon' (above left) remains static (immobile), then there is no difference between
plus or minus time, distance and weight, as from the Timelessness perspective, impossibility of having negative weight, distance
and time, for example, is meaningless, while the impossibility of simultaneously having a negative weight from positive weight's
perspective has a meaning.
Therefore, all what's possible and impossible depend from a 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:
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.
How to get Something out of such Nothing?
Firstly, one must have an ability to make a move, independent of masssymmetry, or Gravity.
Secondly, one must have an ability to move relative to X (time) and Y (distance) axes (above right) at zero mass.
If these two conditions are met, it is possible to get something out of nothing
via Time Shift, where the plus/minus 'balloons' do not have the same center (spacetime coordinates):
The Time Shift sets some strict rules: observations can be made either inside Alpha 'balloon' or Omega 'balloon', not in both simultaneously.
Yet when Alpha (the Bridegroom) is separated from Omega (the Bride), there will be an urge to rejoin.
First, imagine that the center of an infinitely large balloon  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 the 2 possible centers
of Timelessness.
If now to Identify one of these potential centers as the Beginning of Time, and then Locate the other
center as the End of Time, then it would create an observable TimeDistance (spacetime) difference of the balloons' own
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.
A relation between the Beginning (Identity) and the End (Location) can be now experienced and observed via the TimeTension
(gravity) between the opposite mass and light's movement.
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 (past);
2. Black Hole (Event Horizon  the past present);
[Time Zero Asymmetry Flip (mass (time) reversal)];
3. White Hole (AntiHorizon  the future present);
4. Unknown (dark) matter m (an 'antipast' or the future).
