Albert Einstein's said a train approaching the speed of light will

contraction start?

The form of the universe is an hypersphere. This is Einstein's closed
universe finite yet unbounded. If space contracts that hypersphere
would become flat. It would create a pancake universe where one
dimension is disappearing. It simply is not possible for the motion of
an object to cause an outside dimension of the entire universe to
shrink.

Only the time metric contracts. Space does not shrink and distance
remains always the same.

Lorentz and Albert Einstein did.

xxein: No they didn't. Lorentz was very clear about this. It was
mass objects like from atoms to moons. Not space.

Einstein, otoh, leaves it to whatever the math he gives describes to
the beholder. He was unclear even to himself. He bathed in math but
was unsure of the physic it implied. Many of his math interpretations
bothered the hell out of his logic. Not all though.

A careful study of of his writings shows that he was, and remained,
unsure of the physical implications of his GRT math.

I will give you that he could entertain the idea that gravity would
act like a contraction of space just as an overall universal expansion
would do the opposite, but length contraction remained to him specific
to v/c just as his predecessors had envisioned it.

Btw, Einstein received a Nobel for a bogus explanation of the photo-
electric effect. What is "Twice Nobel Laureate 2008"?
