We get it. The Universe is epic, vast, and unknowable, and Earth is tiny. There are black holes billions of times more massive than our Sun, which is also huge in its own right, but it's just one of the hundreds of billions of stars in our galaxy alone.

But the more you hear the "Space is big and you're not" thing, it just starts to feel like words. Because how are you supposed to get a grip on just how big the Universe is, when everything's measured in light-years - which are, you know, 9,461,000,000,000 km (5,878,000,000,000 miles) each?

Don't worry, YouTube's morn1415 is here to help with this incredibly awesome video, which shows the planets and moons of our Solar System and beyond to scale, plus all the different stars that you've probably never heard of, let alone knew how humungous they are. (Our favourite one is called Betelgeuse).

That's all cool and fascinating, but things get really interesting when the video takes a giant step back, and starts to show you the scale of our Milky Way galaxy in light-days and light-years, and then the scale of all the other galaxies, and then out into the cosmic web of galaxies, which is about 5.7 billion light-years across, nbd.

Seriously, if you don't have a borderline existential crisis while watching this, you're made of stronger stuff than us.
