Some people say: humans are so arrogant. exponential science my arse. all we can do is strap something to a massive firecracker. and call it space travel. pathetic. we dont even understand what matter is. we think gravity – the weakest force in the universe – is the most important force in cosmology. we’re thick. I wouldn’t be too concerned at our rate of progress, really. How do you think? Have you though about this…
