When you can tune the fusion of the sun using advanced particle physics and as of yet undiscovered branches of science, you don't need to move planets.

You're not telling me anything I don't already know. The strongest weapons we have /right now/ have no implications for what we will have in the future. A million years is a lot of time. Long live the Earth! We cannot conceive of how we will contain the suns expansion, just like cavemen could not conceive any of our technological advancements mundane to us.

I disagree. The Earth will end, but not in the timelines they provide. In a million years it is unlikely we won't have the technology to hold the sun back from expansion. All we need are orbiting superconducting supermagnets to hold back the sun, tame volcanos, hold back cosmic radiation, etc. Asteroids would be nothing but mining prospects to humans in 1 000 000 AD.
