I remember the 6x8 experience exactly when I was 8. When I was 30 I realised there was another counting system. Counting is one dimensional. Multiplication of 2 numbers is 2D or area. 3D is imagining numbers in a different way. The number billion can be expressed as a line, as an area, and as a volume. Put a billion mm cubes in a line and it is 1000km long. Put them in a cube and it is a cubic meter. This technique, once familiar can give the mind the tools required to realise sizes and distances that are very different to the human observer mind scale. It allows access to the truth. A billion billion synaptic events produce consciousness. We are related to people 1500 ago and in the future through a billion billion connections. Put a billion billion billion mm cubes in a line and it is 100million light years. Put them in a 3D form and it is a cube with sides 1000km long. So the distance is comprehendible, but only with practice. It will take up to 3 years to master 3D conceptualisation, but it is a pathway toward enlightenment as we comprehend the nature of all the science revealed truth
