The third hypothesis maintains that hot Jupiters get close to their star later, when the gravity of other planets around the star can drive the migration. WebOne profound result of Einstein’s theory of general relativity: gravity bends the path of light, much as it affects the path of massive objects. Very massive astronomical bodies, such as galaxies and galaxy clusters, can magnify the light from more distant objects, letting astronomers observe objects that would ordinarily be too far to see. black mountain trail colorado
