1 Discovery that led us

Centuries ago, in 1929 Edwin Hubble made a groud breaking discovery, that the universe is not static but it's continuously expanding with a astonishing speed, that is 90 percent the speed of the light. This discovery led the scientists to change their views about the universe.

One of the biggest question that rises with this discovery was that would we ever be able to explore this entire structure in which our own milky way is just a sand size particle.

To explore the deepest parts of the universe, the earth need to be a type 2 or type 3 civilization which was not possible for the 21 centurion's.
