Hubble's discoveries overturned traditional astronomical ideas and provided foundations for the modern understanding of the universe's size and age.
Hubble's calculation of the distance to the Andromeda galaxy dislodged the long-held assumption that the universe extends only to the end of Earth's galaxy,The Milky Way. This required a major perceptual shift as it suggested that the universe was billions of times larger then was previously assumed.
The new understanding of the universe's size launched an explosion of research aimed at discovering what lies beyond the Milky Way.It also led to speculations that if the universe is so immensely huge it is possible that appropriate conditions for life to exist in other galaxies.
Hubble's Law represented the first coherent confirmation of thee expanding universe theory.In 1917 Dutch astronomer Willem De Sitter and Russian astronomer Aleksandr Friedman devised a mathematical model of the universe expansion.Their model attracted little support but Hubble's Law made it a basic element of the most widely accepted theories in cosmology.The Big Bang Theory first proposed in the late 1920s grew out of Hubble's Law.It suggests that the universe began as a highly condensed point of matter that exploded expanding outward and continuing to expand today.
Hubble's Law has also allowed continuously refined calculations of the age of the universe.The calculations rely on a number called the Hubble constant which is the ratio of the radial velocity of galaxies to their distance from Earth.Hubble's calculation of this constant was higher then current research suggests and his estimate of the universe's age was consequently two billion years much small than the 12 to 20 billion years currently estimated .
The National Aeronautics and Space Administration ,NASA,launched a highly advanced telescope into space in 1990.In recognition of Hubble's legacy this outer space observatory was named The Hubble Space Telescope.While plagued with technical problems which were fixed in December of 1993 on a mission of NASA's space shuttle Endeavor the telescope now sends images to NASA's scientists and continuously compiles further records of celestial phenomena a mission Edwin Hubble would be proud of.
