What I _meant_ to say is that we would _not_ be able to steer. The
particle would disappear, but you would have no idea where it would appear.

But, particles _can move faster than light, the tunneling effect is known
to take exactly zero time to travel some finite distance, therefore speed
of light is not the unbreakable limit we have been taught. Of course,
tunneling is a _very_ _very_ short range phenomenon. now i suppose if
you could controll the tunneling, so that all the atoms in the ship
tunneled a few nanometers at the same time, and then immediatly did it
again, you could in theory travel faster than the speed of light, since
you wouldn't really be in this universe (kinda like hyperspace?) but
that begs the question, when an electron tunnels a barrier, where does it
go between here and there?

No, i said "that i can get my hands on" meaning there are many that I
have never read (like OMNI after they started getting too paranormal)

Since mercury's rotation is on the order of it's orbital period, i think
tracking would not be a problem. Not really sure what orbit a waveguide
As for josepson junctions, i obviously don't know what I'm talking about,
so i will shut up.
