> If human cognition were say, 20x faster relative to the speed of light

What would that even mean, being 20x faster than the speed of light? What does it imply?

[joegibbs]

'Relative to' rather than 'faster than', as in the speed of light being 20x slower or human perception and reflexes being 20x faster, or some mix of the two. If people were thinking way faster then the lag would be unbearable, and there would be no way around it.
