Im not really sure what first sparked my intrest.
But i remember in primary school a teacher took us out onto the school oval to make a scale model of the solar system. We put a basket ball in the centre and so on. Can't remember the exact figures so I worked it out like this:
If pluto was 100 metres from the sun (average) then the nearest star would be around 680 km away.
It blew my mind then, and it still does, and it always will.
To think something like us could exist here through what...chemistry, natural selection?? I love wondering at the big picture, and hope I never 'grow out of it'
