So, if my old brain did the math right, it'll get here in about 2.5 billion years?

Technically the two galactic clouds are already touching, according to some paper I read a couple years ago

I thought something felt funny.

Oh, wow. I expected someone to correct me and say it will be much sooner due to the size of the two galaxies but didn't think I was that far off.

Extremely technical use of "technically" - we're talking about maybe 1 atom of hydrogen per cubic meter, but if that atom is bound by a galaxy's gravity it sort of is part of that galaxy, kinda.
