We can see the future!

Postby Metroid » Tue Jun 03, 2008 8:42 am

Interesting. :-?

Humans can see into the future, says a cognitive scientist. It's nothing like the alleged predictive powers of Nostradamus, but we do get a glimpse of events one-tenth of a second before they occur.

And the mechanism behind that can also explain why we are tricked by optical illusions.

Researcher Mark Changizi of Rensselaer Polytechnic Institute in New York says it starts with a neural lag that most everyone experiences while awake. When light hits your retina, about one-tenth of a second goes by before the brain translates the signal into a visual perception of the world.

Scientists already knew about the lag, yet they have debated over exactly how we compensate, with one school of thought proposing our motor system somehow modifies our movements to offset the delay.

Changizi now says it's our visual system that has evolved to compensate for neural delays, generating images of what will occur one-tenth of a second into the future. That foresight keeps our view of the world in the present. It gives you enough heads up to catch a fly ball (instead of getting socked in the face) and maneuver smoothly through a crowd.

I'm confused. :-S

...if I understand what I think I understood that's kinda cool. But I'm a bit lost myself.

So our eyes are a tenth of a second behind, but our brains are a tenth of a second ahead of our eyes, so in reality, our brains are in the present and our eyes are a tenth of a second in the past. So there's really no future to it. :-D

I wonder if this also plays into how the eyes/brain display uninterrupted sight when we blink, instead of having a mini black out. Guess it would make sense.

Actually this is just part of the FCC's plan to protect us from unpleasant images. Just like 'live' broadcasts aren't really live, so they can bleep out things like Janet Jackson's breast, the FCC now has a slight delay on our vision, so if we see something like a 17 year old girl in a halter top, the FCC can dub in a grandma in a parka. Similarly, we can look for the FCC to build in delays to our hearing and sense of smell so that we can all be free of such burdens as bad language and SBD's.

Very interesting.

Along the lines of the sun rising something like 13 minutes before we see it happening, due to how fast it takes the light to travel.

The Science and Discovery channel are a couple of my faves.
