In theory, at least, the atom could be emitting enough light and oscillating over a large enough area that persistence of vision could result in a visible dot to the naked eye.
- mattkrause 7y agoThis article says it's barely perceptible to the naked eye: https://www.livescience.com/61763-single-atom-ion-trap-photo.html https://www.livescience.com/61763-single-atom-ion-trap-photo... People can detect (though not very reliably) single photons hitting a photoreceptor or ~7 of them entering the eye once they're totally dark-adapted, so that almost has to be true.
- Ono-Sendai 7y agoI believe that's what's happening in this case. From https://www.livescience.com/61763-single-atom-ion-trap-photo.html https://www.livescience.com/61763-single-atom-ion-trap-photo... "This glow would be barely perceptible with the naked eye but becomes apparent with a little camera manipulation."
