Speed and distance
The disk of our home galaxy – the Milky Way – is bigger than we previously thought. A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.
That would be traveling the speed of light which is also unlikely. The Juno Probe is the fastest manmade object. It's speed is 185,000 mph. The speed of light is 186,000 miles per SECOND.
math is hard....
since there are 3600 seconds in an hour therefore it would take the Juno Probe 3600 times as long as light to traverse our galaxy.
The nearest star is 4 light years away. A light year is the DISTANCE it takes light to travel in one year. 31,536,000 seconds per year times 186,000 = rilly big number. times 3600 ....oh yeah..times four.
If an alien civilization could travel a hundred times...a thousand times...faster. It would still take (rilly big number of years) to go take, galacticly speaking, short hops. Star to Star.
Note...assuming we have a handle on Physics. It MIGHT be possible to travel FTL...there is zero evidence to suggest it so it's unlikely though.
Assuming it IS possible to travel Faster than light...
...it'd STILL take years. It'd take longer to go from star to star, even then, than it took Sail Boats to circumnavigate the globe during the age of sail. MUCH longer.
Why bother?
A sufficiently advanced technology, given sufficient energy and raw material...can make any thing they want.
Given sufficient energy the raw materials themselves be made.
Or...virtual reality....ready player one
Which may be the answer to Fermi's Paradox
Why leave their own solar system?
