Re: The universe is how big?

"...the size of the Milky Way is a million times smaller than the size of the Universe,"

This is about right if we use the lower bound for the estimated size of our Milky Way galaxy:

The diameter of our Milky Way galaxy is estimated to be 100-180 thousand light years = 1E5 ly (lower bound)

The diameter of the observable universe is estimated to be 93 billion light years (Gly) = 0.93E11 ly

...so the ratio is about 1:1E6, or 1 to 1 million.
