For those of you who enjoyed yesterday’s thought experiment/mindfreak about how our perception of now is never really “now”, check out this episode of Vsauce.
This video starts with a focus on the time lag that occurs in our visual system, and how what our brain tells us is “now” is actually 80 milliseconds in the past. He also digs into the question we talked about with simultaneous tapping of noses and toeses.
The more we talk about this, I just can’t help but think of a particular scene from Spaceballs:
Colonel Sandurz: Now. You’re looking at now, sir. Everything that happens now, is happening now.
Dark Helmet: What happened to then?
Colonel Sandurz: We passed then.
Dark Helmet: When?
Colonel Sandurz: Just now. We’re at now now.
Dark Helmet: Go back to then.
Colonel Sandurz: When?
Dark Helmet: Now.
Colonel Sandurz: Now?
Dark Helmet: Now.
Colonel Sandurz: I can’t.
Dark Helmet: Why?
Colonel Sandurz: We missed it.
Dark Helmet: When?
Colonel Sandurz: Just now.
Dark Helmet: When will then be now?
Colonel Sandurz: Soon.
