Document Summary

Found excellent evidence: thin layer of clay rich with iridium. Different species in stratum 66m years ago. Asteroid with iridium falls and spreads iridium around the world. Crater of rock found in chicxulub yucatan. The lava flow may have been exasperated by an impact of the asteroid. Added fumes and other stuff in the atmosphere making it uninhabitable to many. ~6mil megatons of tnt collided with the darkside of jupiter. Each of the debris hit jupiter about the size of earth. By reducing glare of reflectivity of the planet, you can take a photograph of exoplanets. Planet and star orbit center of mass. Product of mass and distance on both sides are the same, then you have a balanced center of mass. Stars make a slight orbit as well in response to the orbit of the planet. Indirect detection of exoplanet by looking at the slight blueshift and redshift of the stars.
