can you believe this?

On an episode of "Through the Wormhole" they say all the events of all times are existent

and our brains get (light) signals

but for survival reasons human brain has adapted to only process the present time.

(maybe comparable with the hear which filters some frequencies? or was it decibels?)

at least this would explain how some people dream of future happenings. but......

also I missed the previous minutes when they told the theoretical part about time-space-blahblah.

does anybody has a video on it? or can say why all the events are available.

it's the episode with birds used as atom level particles. I don't know the title in English.
