This reminds me of 'The Gods Themselves', by Asimov. Doesn't talk about a mirror universe per se, but a parallel one. It's one of my favourite Asimov stories outside the Foundation/Robots series.

Personally I think it is Asimov's best work, with I Robot not far behind and Foundation in a distant third. Honestly not sure why people are so enamored of Foundation.

I disliked The Gods Themselves when I read it the first time because of all the freaky alien sex that was described in so much detail. Of course I was a child at the time.

I liked Foundation because of the series aspect - it was a cool premise and it was good to have so many books cover it thoroughly. I did find the last bits that were just to tie it together with the Elijah Bailey stories to be boring.

Indeed other than the big ideas, it really did not age well at all, imo. I like the Elijah Bailey stories and lucky star stories more myself.

This reminds me of the two-part episode in Season 4 of "Enterprise", "In a Mirror, Darkly", which was probably the best episode of the series, and definitely had the very best opening sequence and music of the show.

I liked The Gods Themselves until it got into the freaky three-way sex of the parallel universe aliens.

That's one of my favorites, too.
