I am certain.

It's an interesting video but it's not THE best video I've EVER seen.

I first saw it when it was broadcast 24 years ago.

Since then quite a bit has been found out about our position in the Solar system and only a few months ago a similar picture was taken by the Cassini probe from its orbit around Saturn.

I have a more-than-adequate appreciation of four dimensional space thanks to Professor Sagan.

I remember Flatland too! A great explanation (as was Peter Ustinov on relativity using trains).
