Motion physics app 对比 Powers of 10: Universe tour 的使用情况和统计数据

The nature that we see is full of wonders and beauty. Not convinced? Look out of the window or in the mirror. But it doesn't stop there. The universe is packed with so many more things that we cannot see in our daily life - protons, atoms, cells, distant stars, galaxies and much more. But do you know how small an atom actually is, compared with us humans? Or how large the sun is, compared with the earth? And how many stars there are in the milky way? Powers of 10 will take you on a short journey through all the scales of our universe and will give you a hint of our universe's incommensurable size, beauty and complexity. From attometers to billions of lightyears – on every scale there is something to see.
