rewrite: L′ = L × sqrt( 1 – v²/c² )
I am very surprised by the total ignorance of many physicists (and even.
more cranks) on this notion.
I take advantage of my immense genius, my extraordinary intellectual abilities, and my great didactic sense, to repeat two things:
FIRST: in the frame of reference of the object studied, and on its own length, nothing happens at all.
It is only the observer placed "elsewhere" who will perceive variations in length, a bit like the variations of a Doppler effect.
Note that it is not so much the object that appears smaller (or larger, breathe, breathe) but the observed frame of reference itself, that is to
say space itself.
SECOND: physicists have gotten into the habit of publishing erroneous, and often arrogant, publications which stupidly state that relativity predicts
a contraction of length, and a dilation of time. However, this is not AT
ALL what the Poincaré-Lorentz transformations predict. They predict an elasticity of times and lengths, which seems very different to me from a simple l'=l.sqrt(1-v²/c²) or a simple t'=t/sqrt(1-v²/c² ) which are
only true for an observer watching an object pass transversely.
For lengths the real equation is that of relativistic elasticity, and it
is of the type:
l'=l.sqrt(1-Vo²/c²)/(1+cosµ.Vo/c)
The same equation also exists (because it is the same thing) for lengths
and spatial distances.
D'=D.sqrt(1-Vo²/c²)/(1+cosµ.Vo/c)
Thank you for your attention.

There is no material shrinkage/
A meter stick will remain the same material length in all frames.
However the light-path-length (LPL) of a moving meter stick will be contracted
as observed by the observer:
The LPL of a moving meter stick is 1/gamma meters
This is the length contraction physicists are referring to.
definition:
LPL: the length light must travel to cover the material length of a moving meter stick.

Where would length go to?
Lopsided atoms would distort chemistry.
Does your car shrink where you drive it?

something in its own frame. The coordinate length seen in other frames
is how the length will be measured in them.
Word salad, Stupid Ken. Physicists have SR to explain it and your wordHowever the light-path-length (LPL) of a moving meter stick will be contracted

Lopsided atoms would distort chemistry.Since chemistry takes place between atoms which are moving slowly or are stationary relative to each other, the atoms won't appear to be
"lopsided" relative to each other. No distortion possible.
On the other hand, Roy, if the atoms are moving so fast relative to each other when they encounter each other that they appear
"flattened"/"lopsided" to each other, they are moving at substantial fractions of c relative to each other, WAY outside the energy range of chemical interactions. Their interactions aren't described by chemistry,
but by what happens in particle accelerators or "atom smashers".
Does your car shrink where you drive it?Compared to the road or pedestrians? Yes but the effect at 60 mph is so small it's just not measurable.

Falling through an event horizon atoms and particles go flat.
Yes. You are stupid to believe your car is changing size through
different speeds.
