Or, dump rubbish into it so the surface cools down. But then of course
the inside gets hotter ... not quite a nova by my back-of-an-envelope
calculations, more a bloop, but big enough to thoroughly sterilise any
planets.
How much rubbish did it take to make a measurable effect on the Sun's
surface temperature? And was the rubbish more like iron or more like
chicken bones?
Large parts of Uranus's core and mantle, so something in between iron,
chicken bones, and water. Anything which was dumped would sink slowly if
it's heavier than hydrogen. It would also be less conductive than
hydrogen and mess up the conduction cells at the Sun's surface (which is
what causes the blurp).
As to why people might want to have dumped dump Uranus's core into the
sun 20,000 years before, it was to get the momentum and drive mass to
raise Venus into L4; though by that time Mars had been made bigger with
more core from Uranus and moved to L5, so the L naming doesn't really
apply - three similar mass planets in a common orbit around the Sun..
and it was mostly done with giant elastic bands .. but that's another
story :)
