Even at the speed of light, it would still take about 21 days just to get to Jupiter.
43+ minutes Sol to Jupiter at c. Safe to assume there'll be other game factors.
Happy to see I wasn't the only one to jump on this, If Earth and Jupiter were in perfect alignment to Jupiter and there was no asteroids or other general space debris to avoid it would take around 34 1/2 minutes to travel from Earth to Jupiter at light speed.
With this being said Jupiter was at it's closest point to us in a long time at around 416,000,000 miles (669,487,104 km) this past April ( https://www.usatoday.com/story/tech/sciencefair/2017/04/06/jupiter-closest-visit-earth-astronomy/100128644/ ). This would mean it would have taken about 48 minutes, 33 seconds for one to travel to Jupiter from Earth traveling at light speed. As a comparison in Science Fiction terms, in the Star Trek universe, travelling at Warp 9 (TNG rating) it would have taken one 3.06 seconds to travel to Jupiter from Earth ( http://www.st-minutiae.com/resources/warp/index.html ).
At 1000 times the speed of light it would take about 120 years to fly across the length of the galaxy, assuming you never stopped or slowed down for anything. It is a lot bigger than people think it is.
The size of the Milky Way Galaxy is about 1,000,000,000,000,000,000 km across ( https://imagine.gsfc.nasa.gov/features/cosmic/milkyway_info.html ) meaning traveling at the speed of light it would take 105,700 years, Traveling at Warp 9 (TNG rating) 145 years, or at Warp 10 (TNG rating or 1000 times the speed of light, Voyager rating is different) it would take one 105.7 years to travel from one end of our Galaxy assuming you started at one and travel to the other side with no effects of the center Black Hole.
Sorry but, I find these types of discussions great
