What if you put a powerful laser somewhere on the Earth's equator
pointing up?  Wouldn't it have the effect of sweeping the Galactic
Plane that the article mentioned?

Are you certain that Earth's equatorial plane is the same as the galactic
plane?  I think i read somewhere that both the equatorial plane and the
ecliptic are quite a few degrees *off* the galactic plane.

Yes, the two planes form an angle of something like sixty degrees:
nowhere near the same.
