Asked by: Ben Spindler, Staffordshire

The Universe is expanding at a rate of around 75,000km/h for every million light-years distance, on average. That might sound a lot, but it’s only apparent over galactic distances, where gravity no longer dominates

Everyday objects don’t take part in the cosmic expansion; if they did, there’d be no cosmic expansion, as our standard ‘yardsticks’ would also expand, hiding any change.
