while doing some research on quantum physics and astrophysics i was confronted with a very intruiging notion. It takes an amount of time for a photon to reflect off of an object and reach your eye and then another amount of time to go from your eye to a consious visualization of the sensory input. If we consider this notion to be "true" then does it stand to reason that we are actually seeing the "micro-past"........

what does it have to do with quanum physics..... it has to do with quantum physics because its dealing with the nature of light and consiousness (a "packet" of light being a quantum)
what i would really like to get to the bottom of is what exists in the exact present moment of exsistance knowing observation takes time and particles are collapsed out of a wave function into a point particle simply by the act of observation
then does anything actually exsist in the present other than consiousness and sheer probability?
physics hates the idea of consiousness having any role, but im afraid they are being forced to account for it.
Taking away all perceptive senses you are left with your own thoughts, you are as close to the present as possible (but still not there)....does this not describe meditation?
Libet's experiments suggest unconscious processes in the brain are the true initiator of volitional acts, therefore, little room remains for the operations of free will. If the brain has already taken steps to initiate an action before we are aware of any desire to perform it, the causal role of consciousness in volition is all but eliminated.
Libet's hypothesis was that conscious awareness is subjectively referred backwards in time. We consciously perceive the stimulus as occuring at the same moment it registers unconsciously, even though it doesn't in fact enter our awareness until it has persisted for half a second. Subjectively we backdate it to match the evoked potential at the beginning rather than the end of the 500 millisecond span.
Brain activity correlating with perception apparently occurs too late (150 to 500 msecs after impingement on our sensory organs) to account for actions initiated or completed within 100 msec!
