Speed Limit on Consciousness
In a letter to the Dec. 14, 2002 Science News, Rich Norwood
of Johnson City, Tennessee, writes, “Since consciousness is spread out across
the brain, and since those centers of brain activity cannot communicate faster
than the speed of light, ‘now’ is not the hard point in time we usually
imagine.” Indeed, since neural impulses travel at about 30 m/s, as compared to
300,000,000 m/s for light, “now” is quite indeterminate.
