We are all living in the past - realtime
Interesting story in the New Yorker: What is the relation between the reality, our senses and our brain?
Don't our senses need time to digest what they see, hear, feel? Next there is some transportation time needed to our brain and finally our brain has to put all that stuff together and make some (real) sense out of it. To make things more interesting - different senses have different legacy times and you also have to deal with the difference in the speed of light vs. sound e.g.
So how do we have a sync feeling about things that happen around us? Isn't it so that we have to wait for the last feed to come in? And so: are we actually living in a world that is already microseconds away....
Wow! Maybe even some people have a different legacy time and are living in a different time all together - that explains a lot considering some people ;-))
