The Large Magellanic Cloud , a galaxy which belongs to the Local Group |
With our
current technology sending a human to the closest star will take thousands of
years. Even assuming that humanity will become a type 3 civilization ( an
example of type 3 civilization is the galactic empire in the Star Wars series )
there will always exist a boundary beyond which we could never go further: the Local Group. The
Local Group is the group of galaxies to which our galaxy belongs; it includes
about 70 galaxies , most of which are small in size, which is 0.00000000001% of
the observable universe .
