boost. A particle's forward angular momentum can become backward

angular momentum, if the observer accelerates sufficiently. But the

particle and its angular momentum are unchanged. The only change

is in the observer’s frame of reference.

Could tunneling particles similarly reverseright/leftangular

momentum from a change in the observer’s frame of reference?

The basis for this question is that a spinning object passing through

a surface twice reverses its apparent direction of spin, at least to an

observer on the surface.

Quantum tunneling maybe a result of quantum uncertainty, or

a wormhole, a loop, a tunnel, or some other mechanism. But this

reversal effect does not depend on the mechanism. This effect is

determined solely by the observer’s frame of reference.

This effect can be seen by poking a spinning pencil through a

folded sheet of paper. At one intersection with the paper,

the pencil will be spinning clockwise. At the other intersection, the

pencil will be spinning counter-clockwise, relative to the surface.

But there is only one pencil spinning in one direction. The apparent

direction of spin depends solely on which end of the tunnel (or wormhole

or other mechanism) the observer is looking at. It is purely a relativistic

effect.

So perhaps a Lorentz-boost-like relativistic reversal could occur in

tunneling particles. Has an experiment ever been conducted to test for

such an effect?
