Dimensions ! ?
==.
Euclidean space is a flat two dimensions space without
conception of time .
Put negative time ( -t ) into Euclidean flat two dimensions
space and it will be Pseudo Euclidean space
Put negative time ( -t ) into Euclidean/ Descartes three
dimensions space and it will be negative Minkowski
4D spacetime
Add to (-4D) a new D and it will be Kaluza 5D space.
Add to 5D a new D and it will be 6D space.
Etc 11D . . Etc 26D . . . . to . . . .higher super
- extra dimensions. ( !)
The problem.
Every new dimension was taken from the heaven. (!)
Every new D needs new list of constants, which
were freely specifiable / The trouble with physics.
Page 119. Lee Smolin./, needs new extra particles
- particles not seen in nature, / The trouble with physics.
Page 121. Lee Smolin / , needs new parameters.
#
What is next step?
a) some D must be freeze or hidden.
The real mechanism of the freeze is unknown.
Unless there is some mysterious mechanism that
freezes the geometry of the extra dimensions . . .
/Page 123. Lee Smolin /
b) some D must be wrapped or curled and there are
many different ways to curl them up / page 51, 119.
Lee Smolin / . But the real force (s ? ) of this process is
unknown.
#
What is result?
When you added more dimensions, or more twists
to the geometry, thing always got worse, not better
/ page 52. Lee Smolin /
Why?
Indeed, the more dimensions you include, the higher
/ page 51. Lee Smolin /
( and also the higher the price you pay for curling
their geometry. My opinion.)
#
What is the situation?
In fact, neither theory nor experiment offers any evidence
at all that extra dimensions exist.
/ page XVI. Lee Smolin./
I think the higher super extra dimensions are only
good mathematical toys, it is good mathematical training..
So.
Pecking order of the sciences:
#
I knew many physicists who were sure that supersymmetry
and the extra dimensions were there, waiting to be discovered
/ Page 125. Lee Smolin./
Why?
My opinion.
/ Page 234./
It was discovered in the 1980s that quantum gravity can be
precisely defined in a world with only two spatial dimensions.
We call this 2 + 1 quantum gravity, for two dimensions of space
and one of time. / Lee Smolin./
#
So, what did they do?
At first they added one D and then one D more and more D
and later they began to hide these D and as conclusion (!)
we need only two D ( only 2D - !) and time (!) to explain
quantum gravity. (! ? !? )
I have no words.

P.S.
What is ( 2D+ t) ?
In my peasant opinion ( 2D+ t ) is Euclidean flat two dimensions
space with positive time . Putting mass and electric charge
in this space we make step to understand the gravity.
