Why? Where is the dividing line? And with a Schrodinger's Cat type device a quantum
event can easily be magnified to a macro-event as large as desired, you could connect it
up to an H-bomb.
That's a good question. But I think it has a good answer. "The quantum level" really
means "isolated from the general entropy increase of the universe". The Bucky Ball
Young's slit experiment exemplifies this. If the bucky balls are hot enough to radiate
photons that will provide "which way" information, the interference pattern doesn't
appear. In the t-symmetry model this means the paths don't interact with the rest of
universe. If you tried to send a message back in time via the zig-zag path it would
require an interaction between the wave-function and your macroscopic message forming and
environmentally decohered instruments.
