People like to compare exploring space to the Europeans sailing ships across uncharted oceans in 1400s
It's not similar because we were always going to run back into each other sooner or later. One planet... vs inhabiting many planets, where the possibilities exist that we go to a planet and are forgotten about over time by our fellow humans traversing the stars. 20,000 years pass those solitary humans have forgotten how they got to the planet and have lost all knowledge of space travel.
But haven't figured out a method of instantaneous travel.
Our closest star system is 4 light years away.
At our current top speed it would take us 77,000 years to travel there??
Distance needs to become a breakable law of physics. In theory....if we can travel at SOT "Speed of Thought" -then it won't matter if
it's 4 light years or 4 Billion light years.
The day mankind can travel to the Pleiades system, by simply thinking about it or, waking through a wormhole, that will be the day that mankind may actually gain peace.
Because when that happens.... running becomes the better option than to fight.
Why fight over a planet if there's a chance that you find a bigger, more beautiful planet that no other people know about?
There's more planets in the Milky Way Galaxy alone- than people that have ever existed on planet Earth. Multiply that number X galaxies and there's somewhere that anybody can go to live if the conditions are suitable.
Yes... it's the most Important endeavor of mankind.
