What's a bit strange about this is that the way to move stars is
obvious. Eric Drexler and I discussed it way back in the 1970s.
There is even a nice painting of a star fixed up this way somewhere.
(The artwork even had a slice out of the light sails to keep planets
For those who have not heard about it, you hover actively controlled
solar sails over one hemisphere of a star. This makes the star into a
fusion/photon drive. The acceleration isn't much, but a G type star
looked like it could cross the average distance between galaxies
before it burned out.
PS. For your amusement, the word "extropic" shows up on page 67 of
the Feb 2018 Scientific American.
