“Space is big. You just won’t believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.” Douglas Adams
When I think of objects that are either really big or really small there is a definite limit to my imagination. Once things get past a certain size, I lose all sense of their size relative to each other. Milky Way Galaxy? Horsehead Nebula? Really really big. Gas Giant? Really really big. It’s just hard to wrap the limited human mind around. But that’s OK. Now I have help:
Thanks to Reddit, I stumbled across this neato interactive infographic made by Cary Huang – The Scale of the Universe. You can zoom in and out from the smallest thing in the universe to the biggest thing, the universe itself. Go right now! You will love it. I swear.
Minecraft World: Ok, so technically not a thing in the universe, but its included so I’ll mention it. Minecraft world is huge! At 64 000 kilometres, it is pictured as being on a comparable scale with Neptune and Uranus.
Russell’s Teapot: I didn’t realise there was a stated size for the darn thing, but there is. Its 25 centimetres.
Japanese Spider Crab: Bigger than any spidery looking thing has any right to be (3 metres). Yikes!
Phobos: At 23 kiometres, its about the same size as a neutron star. And both are smaller than Rhode Island. Who knew?
Human Egg: At 120 micrometres it is just barely big enough to be seen by the human eye. Apparently humans can’t see anything smaller than 100 micrometres.
Proxima Centari: At 200 000 kilometres it could easily fit in between the earth and the moon. Except, you know, bad stuff would happen.
Gomez’s Hamburger: it’s a real thing. In space. And it’s enormous, measuring 2.5 trillion kilometres in total, but honestly? It’s a hotdog.
Visible light: those are some teensy wavelengths. Violet light is 400 nanometres, and red light is 750 nanometres. I guess that’s how they fit them in your eye! I’m joking, don’t hit me!
There’s lots more in there to see. Go have a look (but I recommend you turn the music off – it’s annoying). The Scale of the Universe is the Best Thing Ever.
