Distant, massive galaxies will become the new exoplanets as technology to detect them continues to improve. I remember when scientists first started discovering exoplanets, and each time the were always “stunned” to find another. It eventually became so common that it’s hardly news these days, and the same will happen with these massive galaxies.
I’ve always believed two things about the universe — nothing ever happens just once, and it is infinite and eternal.
It’s a great big universe
And we’re all really puny
We’re just tiny little specks
