Human brains are really, really bad at multiplying. This means we can't really imagine a 1000 of something, so the sheer scale is difficult to perceive intuitively. That might be part of the reason, I think.
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
Oh, that explains why lemmy.world was being weird today and yesterday. Thought it was just issues with my account. Thanks for the info!
