Daft question.... but it's getting late. Excuse me for being stupid but.... If space itself is expanding, aren't all our measuring sticks also expanding? So if space was smaller in the past, weren't all the measuring sticks correspondingly smaller? Which would make the Universe the same measured size now as it always was? Albeit less lumpy. Forgive, me it's not my subject - answers in words of one syllable would be appreciated. Cheers, Ron.
