It began in 1907 when Minkowski tried to understand
SRT using 4D space. All SRT’s particles live and act
in this " 4-D negative continuum - Minkowski space "
SRT has only one space - “Minkowski space “ and the
" Minkowski space " is home for SRT
But " Minkowski space " is an abstract theory
and nobody knows what " Minkowski space " really is

Poor young Einstein, reading Minkowski interpretation,
said, that now he couldn’t understand his own theory
“ Einstein, you are right, it is difficult to understand SRT
using 4D space. But it is possible using my 5D space"
- said Kaluza in 1921
This theory was tested and found insufficient
"Well", said another mathematicians, - "maybe 6D, 7D,
8D, 9D spaces will explain it". And they had done it.
But the doubts still remain
"OK', they say, ' we have only one way to solve this problem.
We must create more complex D spaces"
And they do it, they use all their power, all their super intellects
to solve this problem
Glory to these mathematicians !!!!
But… But there is one problem
To create new D space, mathematicians must add a new parameter
It is impossible to create new D space without a new parameter
And the mathematicians take this parameter arbitrarily
(it fixed according to his opinion, not by objective rules)

The physicist R. Lipin explained this situation in such way
"Give me three parameters and I can fit an elephant.
With four I can make him wiggle his trunk "
To this Lipin’s opinion it is possible to add
" with one more parameter the elephant will fly "
The mathematicians sell and we buy these theories
Where are our brains? Where is the logic ?

String theory acts in 11- D space
But if we don't know what 1+1 = 2
how can we know what 5+4 = 9 ?
And if we don't know what is negative Mincowski
space how can we understand SRT ?
