A continuation in the series on Black Holes, examining the inner horizon known as the Cauchy Horizon and its implications on space and time.

Revisiting the theme of time we explain the geometry of spacetime and explore the special quantity known as ‘proper time’. A qualitative post which includes the use of simple graphs.

Of great fascination to me is speed – a simple but often overlooked little quality representing the rate of change of position over time. One of the really exciting things […]
