Could We Move the Sun? (2013)

Impractical ideas. Like having a reflector to push light back at the star causing the star to move. Except the reflector would move too, instead of just the star. Once the reflector was far enough away again, that reflective force would be reduced enough to be useless.

And 'move the Sun'? Relative to what?

(It's a bit like the Dyson Sphere concept. How do you keep the star centred within the sphere?)
