I thought that, in the old theory, the vacuum was also created on the big firecracker?

Given Colbert took the absurdity of conservatism in the US and cranked it up to 11… I’m not surprised it’s becoming reality now.

I think the concept of stars literally hitting each other is rather moot. As you’ve said, the chances are incredibly tiny… However, a star doesn’t have to literally collide with the sun to cause unfathomable damage and destuction.

A star coming closer than the ort cloud will mess up gravitational interactions, orbits, and rain down rocks/ice from the ort cloud.

I don’t know how much of that is factored into the “they won’t collide so don’t worry” formula/logic though

I’m pretty sure it wasn’t renamed because people were morons about child weather, at least not completely. It’s always been “climate change”, because that’s a better representation of what is happening.

The climate is changing, and one is the main side effects it’s global warming… But there’s extra fun side effects, like ocean acidification, that aren’t because of the warning
