Action Quote by Henri Poincare
“Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one upon another, but this action is so slight at great distances that their trajectories are rectilineal; nevertheless, from time to time, two of them may come near enough together to be deviated from their course, like a comet that passed too close to Jupiter. In a word, in the eyes of a giant, to whom our Suns were what our atoms are to us, the Milky Way would only look like a bubble of gas.”
About This Quote
Source Book: Science and Method, Henri Poincaré, 1908
The quote uses the Milky Way as a metaphor to illustrate how vast scales make individual components seem insignificant, yet occasional close encounters can cause noticeable deviations.
In simple terms: On a cosmic scale, stars are like grains of dust, mostly moving straight, but sometimes they interact.
Key Takeaway
Even tiny forces can matter when conditions align.
