        Now I’m imagining the type of event that could cause a planet to move at such a significant percent of c that you could disrupt the sun with it. I don’t think we’re gonna get a planet moving that fast. I think we’d be limited to stellar core remnants to get that kick in velocity.

          That’s not how relativity works. Moving quickly relative to what? The planet might be moving slow relative to the local objects where it began its movement, but the local objects at it’s origination point were also moving at some speed, and the group of objects that the local group was in were also moving at some speed, etc etc. And likewise our sun isn’t stationary, it’s also moving relative to everything else, so you could just as easily say the planet is stationary but our sun was moving very quickly toward the stationary planet. There is no thing as an absolute slow/fast when you’re talking about bodies in space. There are tons of ways that a planet sized object could have a fraction-of-c speed relative to our sun.

          And there are “rogue planets” out there. They aren’t held into any orbital system, they’re just flying free in empty space. So that part is true as well. It would be very unlikely that some of them AREN’T moving extremely quickly relative to the sun.

      You can’t fool me with that label of “diameter”, I know that’s actually a trench with an exhaust port that if successfully fired into will cause a cascading failure

      Okay so I forgot how big the sun is and had that absentminded mental picture moment of “oh it would make a big bang as something 3/4s the size of the sun would hit it”…

      This picture was a very helpful reminder of just how out to lunch that thought was. Don’t trust your absent thoughts, folks 😅
