Yes, I understood that.

I wonder what magazine you read that stated this. Since I've no written
anti-proof I will ask my quantum-physics teacher tomorrow.
I know it is a short range (Low energy level) phenomenon (just like all
quantum-physics) but that it takes exactly zero time I've never heard of.

It still moves 47 km per second, but I don't know how accurate telescopes
are, I will try finding someone who knows, until then I've no other comments
with respect to the problem.

I don't know that much either :| but I listened once to a talk about it
(although forgot most of it). When you brought it up, I went to the library
to sort it out, what I read there faguely reminded me what I had heard before.
