Andrew Allen · Answer 2

It depends on what that "100000" is the amount of.

- - First of all, if it's not a unit of time, then the whole question is meaningless.

- - If it's 100,000 nanoseconds, then the galaxy is about 18.6 miles across.

- - If it's 100,000 weeks, then the galaxy is about 1.81 x 10¹⁶ km across.

- - If it's 100,000 years, then the galaxy is 100,000 light-years across.
