So if you could launch a Moggie into space with some kind of power source installed that would continuously cause the vehicle to accelerate at a mere 1g, ie 9.80665 m/s2 it would only take a year or so for the Moggie to near the speed of light, ie 3×10^8 ms. It would never quite reach the speed of light, but all the same, if you put "pedal to the metal" as it were, you could reach the closest supermassive black hole — Sagittarius A* at the Milky Way’s center — in about 20 years, despite the fact that it’s ~27,000 light-years away.
I think a tune up is on the books!

But to the earth bound observer 27,000 years would have passed
