SUMMARY

Light travels at approximately 299,792 kilometers per second, significantly faster than the human brain's processing speed, which is estimated at 300 meters per second. This results in a perception delay of around 0.3 seconds for elementary acts of perception, as signals must traverse the brain multiple times. Even with light-based systems, the human perception of light remains limited by the slower speed of neural signals, adding 4-5 orders of magnitude to the perceived speed of light.

PREREQUISITES
  • Understanding of basic neuroscience, particularly neural signal transmission
  • Familiarity with the speed of light and its implications in physics
  • Knowledge of human perception and cognitive processing
  • Basic concepts of measurement in physics, such as orders of magnitude
NEXT STEPS
  • Research the speed of neural signals in the human nervous system
  • Explore the implications of light speed in communication technologies
  • Study the relationship between perception and cognitive processing speeds
  • Investigate the effects of light-based systems on human cognition
USEFUL FOR

This discussion is beneficial for neuroscientists, cognitive psychologists, and anyone interested in the intersection of physics and human perception.

How many orders of magnitude faster does light travel than the rate at which the human mind is able to perceive it?
 
Science news on Phys.org
There are too many unknown variables, but, to give a rough estimation,

to make an elemantary act of perception, signals must traverse our brain, say, 100 times. Speed of signals in nerve system is (not sure) 300m/s, which gives 0.3s.

Even if we used light-based systems to think still we would percieve light as 'very fast' - traveling 100-1000 distances of our body/brain when we count 'one...'

But the relative slowness of our nerves adds 4-5 orders of magnitude to that number.
