and the size of our galaxy is: 9.5 x 1020 m (or 950,000,000,000,000,000 km)

Answer:

  • 25 m

Step-by-step explanation:

The scale factor is

  • 1 : 9.5×10²⁰ as we make our galaxy as small as 1 m.

The distance to Andromeda would be:

  • 2.4×10²² * 1/9.5×10²⁰ =
  • 2.4/9.5×10²²⁻²⁰ =
  • 0.25×10² =
  • 25 m
