Big bang balloon
This is a student practical activity that looks into the expansion of the Universe as predicted by Edwin Hubble.
A balloon is marked with dots to represent different galaxies and as the balloon is inflated by various amounts the distances between the galaxies and a 'home' galaxy are measured. The relationship that has become known as 'Hubble's Law' is thus investigated by processing concrete numerical results.
