You’re right. They’re doomed to collide, imo. It’s just a question of when.
But remember, they are in orbit, millions of miles apart. There is a “bridge,” but it’s made of gas, plasma.
We just have to wait for the science teams to finish their analyses. The most exciting possibility for me is that we might get a gamma ray burst out of the merger! Wonder when the Earth was that close to one of those things? It’s only 160K ly away, in one of the Magellanic Clouds.
