Galactica
And I thought Google Earth was cool - what about Google Galaxy? An old colleague Nik Roope had this image on his blog which shows the scale of Earth compared to other stars in the solar system and galaxy.
It reminds me of some of the explanations in Bill Bryson’s book A Short History of Nearly Everything, such as his comparsion of a year in time to a metre in distance: The 2nd World War ended 60m away, Jesus died 2km down the road, the first agriculture appears at 10km, Homo Sapiens emerged 300km away, Dinosaurs died out 60,000km away etc. etc. Mind boggle.
