Is the present an illusion?

If light takes 20mins to get to me from the sun it must also take some time to reach me from objects before me and if nothing travels faster than light then everything I perceive is in the past so doesn’t it follow that the present is an illusion?
Tony Chapman from Lancashire (Age 55+)

  1. Hi Tony. When you read this it will be long after I wrote it. Does that mean it’s an illusion? No, your experience is real. When you look out of the window the light entering your eyes left the objects you see a tiny fraction of a second ago, but that lag pales into insignificance beside the delay introduced by the need for your retina to become activated, for messages to get from there via various relay stations into your visual cortex, and finally to trigger recognition systems in your head. It is not until that final stage that you ‘see’ the objects. Your sense of the present is real and justified, although it is acquired just a little after the events that gave rise to the sensation.
