Reply to comment by Tupcek in Is dark matter orbiting galaxies with the same speed as normal matter? by taracus
There isn't a lot, no. Dark matter is very diffuse; in all likelihood there is some streaming through the planet every second of every day, but since it doesn't really interact with baryonic matter much if at all (similar to how neutrinos don't), studying it would be exceedingly difficult. There have been many experiments similar to current neutrino detectors looking for dark matter interactions but none have been found to date.
