there are only three dimensions..T time, is not a dimension, throw the T

Who, according to your research, says either one, and where?

> Just tell me the MLT dimensions of "space-time"

There are no “MLT dimensions of space-time”.  You are confused as to the 
proper use of the term “dimension”, and you do not understand yet what 
“space-time” is.  You must realize that there are different definitions for 
the term “dimension” as there are different contexts in which it is used, if 
you are going to understand “space-time” in physics.

<http://www.wolframalpha.com/input/?i=dimension&dataset=> pp.

Relevant here:

On the one hand there are dimensions in mathematics, of geometric manifolds, 
which are degrees of freedom in the choice of coordinates in such a 
manifold. 

<http://www.wolframalpha.com/input/?i=dimension&dataset=&rawformassumption=%7B%22C%22,
+%22dimension%22%7D+-%3E+%7B%22MathWorld%22%7D>

On the other hand there are dimensions in physics, of physical quantities 
which can be described in terms of combinations of the quantities mass (M), 
length (L), and time (T).

<https://en.wikipedia.org/wiki/Dimensional_analysis>

It just happens that because mechanics is concerned with the motion of 
bodies, it is useful in physics to consider the mathematical concept of 3+1 
space(-)time, as a body always occupies a particular position in space at a 
particular time.  Whereas motion can be described as a change in three 
spatial coordinates and one temporal coordinate.

No, it shows instead that you make unsubstantiated claims.

No, AISB it has three spatial dimensions (that can be compacted into one 
dimension, space) and one temporal dimension (time).  But those are 
*mathematical* dimensions, ways of how the *coordinates* of an object can 
change.

By contrast, mass and length, and by extension of length, area ([area] = 
[length]²), are *physical* dimensions of *quantities*.

> but you say it exists.

It exists insofar as that we can indeed observe the effects that would 
follow if the theories using it would be correct.  IOW, the predictions of 
the theories have been confirmed by observation again and again.

As you are probably aware, recently predictions that followed from assuming 
the correctness of the general theory of relativity, in particular a curved 
spacetime, curved according to the energy–momentum in a location, had been 
confirmed once again by the experimental observation of gravitational waves.

No, they are not.

Not really.  “x”, “y”, and “z” in the referred equation are appropriately 
chosen labels for the spatial *coordinates* of an event, a position, in 
spacetime.  “t” then is its one temporal coordinate, time.

The referred equation means that if you make the differences between 
corresponding coordinates of two points infinitely small, you can arrive at 
a way to measure distances between all possible two points in that flat 
manifold.

> and x^2,y^2,z^2 are their respective AREAS;

Only in an overly simplified sense.  “dx²” must be read “(dx)²”; _not_ 
“d(x²)”.

You misunderstand.  I said that there are different definitions of the term 
“dimension” in physics.  One of them is borrowed from mathematics, from 
geometry.  The one you are referring to is not borrowed from mathematics, 
and you are confusing it with the former.

Because one (the mathematical one) concerns position only, and the other one 
concerns all physical quantities.  There are, of course, physical quantities 
in the theories of relativity as well (they are physical theories after 
all), and they do have dimensions there in the quantitative sense.

But spacetime *itself* does not have *that* kind of dimensions; it has the 
mathematical kind instead.  So your question regarding “the MLT dimensions” 
of spacetime does not make sense; it betrays a fundamental lack of 
understanding what spacetime is.

> Show what YOUR understanding of Space-time is,

My understanding, which is equal to what is being taught in mathematics and 
physics classes since more than a century, is that spacetime is a 3+1-
dimensional manifold.

No, I did not say that.  I said that there are the dimensions with which 
you determine position and distance, and there are dimensions which which 
you *can* define the form of physical quantities.  Those are *separate* 
concepts.  You are committing the fallacy of equivocation here.

> which makes it as USELESS to real physics

On the contrary.  The mathematical dimensions of spacetime are fundamental 
to describing how physical quantities change when objects are in motion 
relative to one another.

Why?  Well, one quantity important in motion is speed.  Speed is 
the magnitude of velocity, and velocity is the change of *position* per 
unit time.  A position has *coordinates*.  Which coordinates determine 
position is the subject of geometry, of mathematics.  

If speed is measured relative to another object, it is important how 
distances to that object and times on that object are measured.  So
you see that there really is no contradiction in applying in physics 
*both* definitions of “dimension”, but in different contexts.

<https://en.wikipedia.org/wiki/Special_relativity#Physics_in_spacetime>

> So, tell why the motion of bodies _in_ space & -in_ time is

There are several ways to explain it.  I prefer to start with the fact that 
all experiments have shown that the speed of light is constant in all frames 
of reference.  Spacetime then provides a convenient mathematical framework 
to describe the observed effects that follow from that.

> None of the agencies of the world's space faring nations
> do use SR or GR for determining the trajectories of their SVs

Because the speeds of those space vehicles (SV) are so low compared to the 
mindbogglingly huge speed of light that (what we know since more than a 
century) the *approximations* of classical mechanics suffice there:

  lim  γ(v) = lim 1∕√(1 − (v∕c)²) = 1
  v→0         v→0

    [γ(v) is the Lorentz factor for speed v which determines the degree of
     length contraction and time dilation.  As γ(v) approaches 1, it
     becomes increasingly harder to observable any length contraction and 
     time dilation.  If necessary, equations for both can be provided here
     *again* to demonstrate this.]

However, SR and GR become important where electromagnetic signals are 
involved, as those travel at the speed of light.  One such kind of signals 
are those of global navigation satellite systems (GNSSs).  The trilaterated 
position of the observer on the surface of this planet would be off if both 
SR and GR would not have been considered in the design of the hardware and 
the software of the satellites of those systems and the receivers on the 
ground:

The part about my working “in any physics lab” is true.  But with your 
insufficient knowledge of physics and your uncivilized behavior, neither can 
have you worked there (not even as janitor).  So much for “Groessenwahn” (I 
would recommend that you *learn* German before you use German words in an 
attempt to deride statements of a born German – it is properly spelled 
either „Größenwahn“ [Standard German] or «Grössenwahn» [Swiss Standard 
German]).

> but Lahn busily echoes physics quackery that he saw on the internet […]

You cannot know what I have seen and where, and you have yet to understand 
the subject of our discussion.

JFYI, I have also heard lectures, and read books and papers on the subject, 
and been to “physics labs” and talked to physicists (seeing the inside of 
the CMS experiment first-hand and talking to CERN people in 2013 was great; 
I recommend to readers that they take the chance and visit CERN openlab Open 
Day 2016 in June) – all of which you have yet to do.

But I fear that with you all of it would be just pearls before swine.

Now, do you know How To Hack GPS??


You can learn how to digitally fake a traffic jam by creating phony
profiles on the traffic and navigational app Waze, 
you can fool cops GPS to head straight to a traffic jam....make your
getaway easy.
