Just learned the newer estimate of galaxies in the visible Universe is 4T, ten times more than stars in the Milky Way; though, my guess is both estimates are too small.
Wow! More than four trillion galaxies in the visible universe !
There are more stars in the universe than every grain of sand on earth.
William Blake's poem.
It sounds beautiful.
I can only hear the voice of Carl Sagan when asked that question.
Billions upon billions . . . .
Its more like the number of googolplex.
Billions and billions sounds too Trump like.
