      Light has a finite speed. So whatever our eyes see happened in the past. If what you’re seeing is near you, light will take just a few nanoseconds to bounce off the object and into your eyes (but it’s not instantaneous). If you’re looking at the stars in the sky, you may be looking as far as millions of years into the past. We never see the “present”.

        Not only that, but electricity travels through nerves at a finite speed (that is less than light speed), and brain spends non-zero amount of time to piece together the reality you perceive from all of your senses. So yeah, there’s always a delay in your perception and IIRC there even are experiments that prove that

    So a blind person doesnt live at all?

    Dont you have other senses and organs? Dont you have a mind that anticipates a present even without other senses?

    The post is a funny scientific fun fact about lightspeed but thats about it
