As I understand, the first spirals were all "normal", then more became barred until now at least half are.
Does that mean that in 20 Gy all spirals will be barred?
Or will they all be ellipticals by then, like Milkomeda?

I have to admit when I first read the title of this thread, I thought that politicians somewhere were going a bit too far!

This is being spun way too much.

It's pretty twisted, isn't it?

I think the moderators are getting pretty torqued.

On topic (where were we, anyhow?), I suspect that n-body simulations are not sufficiently robust to follow billions of years into the future, at least until we can be sure about the distribution of dark matter and of dust and gas within galaxies.
