For example, "defining" the second as about the
cesium atom its hyperfine transition, and "defining"
the meter as that according to the "defined" speed
of light, results all that's defined not derived,
the System Internationale units that we all know
and love simply don't say much about the objective
reality of the quantities.

Nothing that you have the wit to understand?
The are a lot of steps between the optical spectrum of a
cloud of cesium
atoms and the frequency of an oscillator running slowly
enough for you
to be able to count transitions, but there is no question
about the
objective reality of every last one of them.

Eh, the basis for the SI is the defined value
for a -microwave- frequency of the Cesium atom.
From an engineering point of view a Cesium clock
is nothing but a stabilised quartz clock.

That "nothing but" ignores the fact that the output of the
cesium clock
has a much more stable frequency than the outputs of regular
quartz
clocks. That's why people pay more money for them.

Of course, it is a stibilised quartz clock.
I thought you were proud of being an engineer,
so I adapted the description.

Optical frequency standards do exist,
such as Strontium lattice 'clocks' for example,
but so far they are frequecy standards only,
not yet clocks.

Like I said, they are called 'clocks'
but for the time being they are only frequency standards.
(precisely because they cannot be used yet to stabilise a quartz
clock)

The process of turning a frequency standard into a clock is
fairly
complicated but the devices are already sold as clocks.

From an engineering point of view that is just being able to

It is total bunk to assume, that an 'external' clock would exist,
which synchronizes everything in the universe.

Clocks don't exist to synchronise anything. They can be part of a
local system which synchronises some local action to an event which
has been observed from that location. Granting the bulk of the
universe is expanding away from any given point at a speed which is
increase with time and distance time dilation alone makes the idea
of perfect synchronicity untenable.

If nothing synchronizes remote systems, then how could we rightfully

It's a very convenient assumption.The big bang theory has the
universe starting to expand from a very small point some 13.8 billion
years ago, and what we can see of the observable universe is
consistent with that.

Sure, it's convenient.

But is it actually true???

We don't seem to need a different explanation at this point.
If eventually make some observations that are inconsistent with the
theory, we'll start looking for a better one, but the big gbang theory
seems to be true enough for all current practical purposes

Big bang theory suffers from a 'little' problem:

how would you actually create a universe from nothing?

Nobody said anything about creating it from nothing. The point about the
theory is that it starts off with a large lump of undifferentiated
mass-energy that doesn't have any structure that links it back to a
preceding structure. The early stages of its development seem to have
been pretty well randomised, and if the mechanism that created initial
the lump of mass energy was merely the collapse of a previously existing
universe we'd end up with essential;ly the same theory.

This 'white hole' spreads out and creates, what we call 'universe' in

But 'universe' isn't universal at all and the timeline from big bang

But since we can't observe any of these other universes it is a complete

Our past is just one of an infinite number of possible timelines,

But you need to find a mechanism that lets you explore these other
timelines before anybody is going to take you seriously.

This is more like a HUGE clock with one hand only, that circles once
every ten billion years or so. This 'hand' moves slowly forewards and
creates new universes every time it moves.

If you want to imagine something like that, feel free, but don't expect
anybody else to be interested. You won't get any research grants to
support any work you might want to put in to make the idea sound less
half-witted.
Now new universes need new stars and those new planet.

What we can see is mass-energy redistributing itself. There's no
evidence that more is being created.

The overall picture of my approach assumes a 'real universe' which is

Not that you've got a single piece of evidence that supports this

The latter 'relative matter' is actually, what disturbs the most,

So it's the central silly idea, which doesn't make it any less silly.
If you've written a book about it, and self-published it, you are
extravagantly silly.

There are many outfits these days claiming to economically
make sustainable aviation fuel and other fuels like gasoline
from carbon from carbon dioxide in the air and hydrogen from
dihydrogen monoxide the water via electricity from usual sorts
of renewable means in a sort of carbon-neutral liquid fuel setup.
It's not even particularly high-tech.
But that's not what Thomas Heger is being silly about. Making
hydrocarbons from water, sunlight and the CO2 in the air is what plants
do, albeit not all that efficiently. There are other ways of doing it,
which don't involve plants and DNA, but none of them seem to be cheap
enough to be all that attractive.
Burning fuel, and next throwing lots of energy at the atmosphere
to get that fuel back is kind of silly to begin with,
