Literally speaking. You know the fabric of space is expanding into infinity at some accelerating rate. You could take some recent instantaneous speed of expansion and calculate how big something is today compared to how big it was yesterday. Was an elephant the size of an ant yesterday? Or even smaller?

These questions are perverse but interesting. One time I figured out how loud the Sun would be on Earth if there was air between here and there to carry the sound. Don't remember the figure but it seems like it was off the decibel scale. So loud that you couldn't tell if it was any louder. Damn loud. Seems like it was on the order of your ear 1 inch away from a jack hammer.

Hmm. Wouldn't be able to tell if everything was expanding or shrinking at the same rate but fun to consider.
