Based on various measurement tools at different ranges of distance (trigonometry, parallax, standard candles, supernovae brightness, galactic red shift and the cosmic microwave background), it is possible to create a cosmic distance ladder and accurately determine not only the distance of far-flung galaxies, but also the current size of the universe.

How Did Scientists Determine The Size Of The Universe?


I understand "measurement tools at different ranges of distance" as "measurement tools that are used for different ranges of distance". Am I on th right track?

I've checked out an unabridged English dictionary, which doesn't show a definition like "used to indicate purpose or capacity" as I've expected. Henc the thread.

I would gather from that that some measuring tools are more useful than others depending on the distance.

(I am not an astrophysicist.)
