What it looked like when the moon was made 4.6 billion years ago. In 3D, and with modern cities etc to better show scale.
This is a simulation of an asteroid hitting Earth, which then made the Moon. It was produced by the Japanese equivilent of the BBC as part of a TV documentary. The audio is in Japanese, but clicking the ‘more’ link to the right of the video itself will display the translation for you to read. A truely awesome sight.
