Right, and not understood by people who see the Big Bang as an explosion of material through space.

(2) seems a bit confused (confuses me anyway smile ):

'everything moves through spacetime at...the speed of light'

- Photons do. We don't.

'Light does all its travelling through space, which means it is static in time'

- Time passes as photons go from A to B.

'we do most of our travelling through time, and a very limited amount through space'

- When we travel faster through space we also travel faster through time?
