Document Summary
1- (100y) ptolemy = geocentric - earth in the middle (god beyond) = successful scientic - accurate to find planet at right place. 2- (1000) copernicus = sun in middle - right general idea (epicycle-cycle on cycle) = but less predictable (more traditional) 3- (1600) frontenelle = sun & other stars w/ other planets around (guessing) 4- (1900) chamberlin & moulton = star passing close to sun cause prominence -> forms/make planets. * very unlikely for star to pass so close (no collision) - no belief that other planets around stars. 6- (1963) van de kamp = planet orbiting around suns- claim star moving around because orbiting of. Planet - but instrumental error/calibration (cleaning of lens= diff results) Paper ubc - maybe solar system rare - no jupiter-mass companion around other stars. 7- (1976) viking landers= belief vegetation on mars but found nothing. Meteorite from mars = microbial life & found ocean under ice on some planets/stars (europa/callisto)
