Measuring the Universe

Measuring things that we can touch, feel and see up close is easy. No matter the exact method, we mostly just use big rulers down here on Earth.

But how do we measure the universe? How do we tally distances on a scale of time and space so immense that our brain can quite literally not reconcile them? 

Here’s a fantastic animation by the Royal Observatory to answer that question.
