Hey there,
Reading a book today, I stumbled upon a section where the expansion of the universe was discussed. The numbers were not constant, and although I did not get to finish, there is something that puzzled me. At a certain point, the book talked about an expansion rate of 70 kilometers per second per megaparsec. As far as I figured, a parsec is 3.26 light years, and a megaparsec is one million times that numbers. However, what exactly does it mean to expand per second per megaparsec? Any explanations pertaining to the topic will be greatly appreciated. Thanks!
