Happy Birthday, Ernest

Nga ra o mua is a Maori phrase for the past; translated as ‘what is in front’. The past is spread out in front of us – it’s what is known. It’s literally true when we look at the stars: the light we see left the stars perhaps millions of years ago. The past is spread out in the sky. Nga ra o mua also fits the physics concept of a universe in which all points of time exist together. For example, about now on August 30, 1871, Ernest Rutherford is being born. It also explains why it’s hard to leave the past behind.  Pam Morrison wrote eloquently about this in her blog. Photo: a million stars (NASA Images)
