Off topic but in a sci fi hypothetical, would there be a way to make out sun bigger to go supernova ?

  I could be wrong but I don't believe there's enough mass in our solar system for it to be close. Solar systems do merge with one another, stars bring other stars into their orbit, etc. It would take something like that, I believe.

  Not any way that wouldn't just let us move to a star that will go supernova, I don't think. I just looked up the mass of the solar system, and got the gut-punch answer of 1.0014 solar masses. Considering that it seems to take 8 or so times as much mass as the sun for a star to experience a supernova, we could trivially just move all the non-star mass in the solar system elsewhere for several fewer orders of magnitude of effort.

  Well, the Milky Way and Andromeda galaxies will be merging, so there's an infinitesimal chance of a stellar collision with our Sun. (The odds of any stellar collision are, ahem, astronomically low, but you asked)

  Throwing out some undercooked ideas for supernova-ing a star, from possible to impossible: 1. Throw more mass into it, ideally 1+ stars under their own power via Shkavov thruster. 2. Compress it physically with mirrors and particle/photon beams (see inertial confinement fusion) 3. Compress it magnetically with incredulously powerful magnetic fields (see tokamak fusion). 4. Compress it gravitationally by putting a black hole in its center. 5. Make it more explodey by converting half of its mass into antimatter.
