I enjoyed reading this article, even though it was indeed hard to wrap my mind around the concepts, until I ran into this sentence and my mind just bounced off completely. Is there something missing here, or can someone explain this in different words?

“ The gravitational force inside an atom is entirely negligible relative to the gravitational force . . .”. (seems to say “X is negligible relative to X”)???

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
