If we were to speed up by a factor of ten, that would be 1.1 years.
Voyager 1 travels at 38,210 miles per hour.
38,210¹⁰ is what speeding up by
a factor of ten would be and that would be 6,633,922,244,353,631,530,722,098,806,688,562,010,000,000,000 mph, which would far exceed the speed of light which is only 670,616,629 mph.
At 6,633,922,244,353,631,530,722,098,806,688,562,010,000,000,000 mph it would take me less time to get to Alpha Centauri than it did for me to type this message.
