dark matter hypothesis
In article ,
jacobnavia writes: IF the halo is spherical THEN the study is right. If the halo is NOT spherical but follows the plane of the milky way, i.e. most dead stars are in the galaxy plane and WITHIN the galaxy, that study proves nothing. Aren't there also microlensing studies towards the Galactic bulge? Now, most stars that go supernovae have non-symmetrical explosions that could propel their "dead" corpses in random directions, but the galaxy's gravity should hold most of them back and keep them within the galaxy plane. How would motion perpendicular to the plane be damped out? -- Help keep our newsgroup healthy; please don't feed the trolls. Steve Willner Phone 617-495-7123 Cambridge, MA 02138 USA |
