If man was not meant to explore and colonize distant worlds and galaxies...

...why is the universe there?

Just because things are there, doesn't mean we'll be visiting !

Fastest spacecraft so far, is slower than light speed by a factor of
over 30,000 ! But even at light speed, travel to the nearest next
galaxy would take 2.5 milliom years ( one way ) ! That's 2500
MILLENNIA ! So the fastest spacecraft would take 75 million millennia
to get even to nearet galaxy Andromeda !

To put things in perspective, only a measly 2 millennia ago, was the
start of the Roman empire !


Note that according to Einstein's relativities and confirmed by all
observations, there is the ultimate speed limit of light speed on
everything.
