Скачать или смотреть Parsec - The Strange Distance That Makes No Sense

A parsec sounds mysterious, abstract — and completely unintuitive.
Yet it’s one of the most important distance measurements in all of astronomy.

In this documentary, we unravel what a parsec really is, why astronomers use it, and how this strange unit of distance helps us map the universe.

You’ll discover:
– What a parsec actually measures
– Why it’s based on geometry, not speed or time
– How parallax allows astronomers to calculate stellar distances
– Why parsecs are more practical than light-years for astronomy
– How far a parsec truly is in real-world terms
– The limits of measuring distance in space
– How parsecs help define the scale of the galaxy and universe
– Why this unit seems confusing — yet makes perfect sense

Once you understand a parsec,
the universe suddenly becomes a little less mysterious — and a lot more fascinating.
