At least no model in science so far has yielded absolute truth.

What is - really, truly, scientifically - the space?

Well, it is the following:

- that is something that contains everything. And that "everything" is, essentially, the energy, packed in different ways/forms.

- that is something in which we can notice and measure that what we call "lengths". There can exist maximally three straight line segments which are mutually orthogonal (perpendicular) and which cross each other at one and the same point, and that is why we call it the 3D space.

- that is something that has the following two,

*detected*,

*measured *- that is -

*scientifically proven* properties: the lengthwise capacitance [tex]\epsilon[/tex] (a.k.a. electric permittivity), and the lengthwise inductance [tex]\mu[/tex] (a.k.a. magnetic permeability). Because of these two properties, electromagnetic properties, the space is an electromagnetic phenomenon.

The elementary existence manifestation, the most elementary entity, which manifests its existence within the space, is the photon.

Photon's properties are: energy, EM-oscillation period, wavelength. It moves. "Moving" is the way it exists. There are no photons which do not move. And they move with the velocity which is determined with [tex]\epsilon[/tex] and [tex]\mu[/tex] properties of

**space**.

Time is that what gives sense to existence. (Without it, we could not determine, we could not define the existence. Without it, some entity could pass some distance "in no time", so it could be throughout the space. So, that entity would be everywhere. Everything would be everywhere. So, space and that what has energy could not be distinguished. There is no need to continue this elaboration, since it is obviously absurd).

Time is the axiom of existence. How is it related to existence? Well, it is one of five axioms of existence, four of which are related in the following way: [tex]t = s \cdot \sqrt (\epsilon \cdot \mu)[/tex]. The fifth axiom of existence is energy. Its elementary manifestation is the photon. The time is related with energy in the following way: [tex]\Delta E \cdot \Delta t = h[/tex], and that directly follows from [tex]\Delta E = h \cdot \nu[/tex].

[tex]s[/tex], [tex]\epsilon[/tex], and [tex]\mu[/tex] are axiomatic properties of the space. Hence, due to the relation [tex]t = s \cdot \sqrt (\epsilon \cdot \mu)[/tex], [tex]t[/tex] is also an intrinsic, inherent property of the space. That is why the space is the

**spacetime**.

All of the five axioms of existence: lengths, time, [tex]\epsilon[/tex], [tex]\mu[/tex], and energy, affect each other, and all of them change continually.

"We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances. Therefore, to the same natural effects we must, so far as possible, assign the same causes."

_{Sir Isaac Newton}And, we do not need the Minkowski spacetime postulation to explain the reality. Minkowski's idea was right, but the model of that idea is wrong. With Minkowski spacetime postulation, and Einstein's postulated tensor equation, we can only approximately model the reality, and we cannot understand it in that way. It is just some nice, abstract mathematics, which produces approximate results, which model but do not explain anything. The goal of science is to understand, and not just to model. Ptolemy's helicoids described the movement of celestial bodies well. But that provided no understanding at all.

"A man may imagine things that are false, but he can only understand things that are true, for if the things be false, the apprehension of them is not understanding."

_{Sir Isaac Newton}"The noblest pleasure is the joy of understanding."

_{Leonardo da Vinci}The results, the final equations that Einstein-Minkowski postulates yield, are not in accordance with continuity principle, and with energy conservation principle. (And there are even worse consequences. And being worse than non-compliance with the continuity and energy conservation is really, really bad situation. And accepting that as science is extremely bad situation).

P.S.

"We can’t solve problems by using the same kind of thinking we used when we created them."
