So the speed of light is measured at exactly: 299,792,458 m/s.
Speed of Light
So barring no other interruptions in processing, you would still be processing information from 1/299,792,458th of a second in the past.
Now you have to add in the time it takes the light to travel from its source, to bounce off of the object being viewed, to be redirected to your eyes,
and then the time it takes your brain to actually process the image.
It takes the average human brain between 300-700 milliseconds to process and understand a nervous input. So lets add another 1/700,000 of a second to
the equation.
Now given that the light source is one meter away from an object and that object is one meter away from you, it would take the average brain:
1/600,284,916th of a second just to realize what is being seen in front of them. In other words it takes you 600,284.916ms (milliseconds) to process
what is going on.
Seems pretty fast!
Until you realize that in fast-fission nuclear reactors that the prompt lifetime of a neutrino is only 10^-4 to 10^-7 seconds. These extremely short
lifetimes mean that in 1 second, 10,000 to 10,000,000 neutron lifetimes can pass.

Chain Reactions
And, given that the low-ball estimate for the number of neutrinos that the sun passes through your body is in the range of 6.4^14 neutrinos/second
(and this is ignoring all other sources other than the sun):
That would mean that the universe is affecting your body at the minimum of 640,000,000,000,000 times per second...
Heck, I wonder how many times
You have been affected by the universe in the time it took you to read this post, or this word, or even the time
it took the light to pass from your computer screen to your eyes...
Makes you scratch your head when you think about it
