Dark matter Quote by Sean Carroll
““Christopher Savage have calculated that in reasonable models, we expect about ten dark-matter particles to interact with the atoms in a typical human body every year. The effects of every individual interaction are pretty negligible, so don’t worry about getting a dark matter stomachache.””
About This Quote
Dark‑matter particles rarely interact with human bodies; any individual interaction is negligible, so there is no practical health concern.
In simple terms: Dark‑matter collisions with us are harmless.
Key Takeaway
Infinitesimal particle interactions pose no danger.
