Document Summary
Why not machos? lomoar cpsd| 2151316 lomoar cpsd| 2151316. Massive project aimed at looking for low mass stars, blackholes, etc in the milky way outskirts. Mass is not high enough to add up to the amount of dark matter in the universe. If the dark matter were all in neutrinos structure in the universe would have formed anti-hierarchically so what do we know about. ~90% of the mass of galaxies, extends well beyond the visible parts og alaxies. Something that does not interact with light (at any wavelength) The answer isn"t known, but evidence in favor for particles over stars etc. Future for dark matter: particle physics, create and observe dark matter in the lhc direct detection of dark matter. Very rare scattering events deposit some energy into a detector. Other things also scatter o of nuclei, need to remove backgrounds (put underground) Expect more detections at certain times of the year. Creating and detecting dark matter at the lhc.
