Our sun grew fat when a sausage collided with the Milky Way

I wonder just how you might actually prove that even though it appears to be almost self evident.  however after seeing how Jupiter sponged up a few Comets in recent history, i am more inclined to expect the inevitable binary object to do most of the heavy lifting and then possibly spin up to eject planets.

 

See how easy it is to make all this complicated and how the sun can miss most of the action.  Everything arrives on an orbital path of some sort and few will be dead into the Sun.  Most material  will be actually be dominated by Jupiter into a capture orbit.   

 

This can also be used to explain the dominance of binary stars out there.   .

A collision 8 to 10 billion years ago between our own Milky Way and a smaller galaxy dubbed “the sausage” helped grow stars in the centre of the Milky Way, including our own sun. The smaller galaxy was torn apart in the collision, providing extra gases to fuel star formation.

The crash would have lasted many hundreds of millions of years. Stars from the smaller galaxy have ended up with strange, sausage-shaped orbits around the centre of the Milky Way …
