Every time the physicists think they have found the smallest bits, then they are afraid they will be out of a job. So they invent something even smaller.
From the Frontspiece of "Dark Matter, Missing Planets and New Comets (Paradoxes Resolved, Origins Illuminated)" by Tom van Flandern.
The First Cosmology:
"The world is not flat, as it appears, but round, like a ball."
"Then what holds the world up?"
"The great god Atlas holds the world on his shoulders."
"But what does Atlas stand on?"
"He stands on a huge island."
"But on what does the island rest?"
"It rests on the back of a giant turtle."
"No need to ask further. It's turtles all the way down!"
