First sighting of 'neutrino fog' sparks excitement - but is it bad news for dark matter?
Briefly

"On the one hand, it means that detectors have become sensitive enough to pick up signals of dark matter - the mysterious substance thought to make up the bulk of matter in the Universe. On the other, it means that the neutrino signals could obscure the dark-matter signals that scientists are so eager to observe."
"The neutrino fog is also exciting because measuring it confirms that dark matter experiments are capable of observing all 'flavours' of neutrinos flying in from the Sun and even from exploding stars in nearby galaxies."
"Physicists have long predicted that dark-matter experiments will eventually catch a glimpse of this neutrino fog, formerly known as the neutrino floor."
"You could learn something about the total spectrum of all neutrinos," she says. This opens new doors for comprehensively understanding the universe's fundamental particles.
