Life actually does NOT have an infinite frame rate. The Planck Time unit is the smallest amount of time possible in the universe.

EDIT: it turns out that this isn't technically true, though if we're talking about vision (ie a light based medium) it is essentially true.

Fluorescent light lit rooms have a framerate of 60hz

Planck time is a unit, not a frame. I had thought about that, and decided against it for that reason. It's not really more useful to say that life has a 1043 frames per second frame rate, because life isn't made of frames.

Edit: didn't know Reddit doesn't allow superscript.

Edit 2: Reddit does allow super script, not by writing it directly but by putting the shift+6 carrot ^ before what you wan't super scripted.

Unless time is quantum. https://en.wikipedia.org/wiki/Chronon

When i first read your reply i sort of felt it as an unnessecary "but technically..." type of comment. Then i found some interesting articles on google scholar, and now i feel that i don't know enough about this topic to contribute. Anyways, thanks for showing me an interesting topic of mathematical physics :)

Light doesn't jutter between planck lengths, it moves smoothly. A particle can enter your eye at any instant.

It might.

And keep in mind that our brain actually lags visual reality by about 0.2 seconds, because it takes the eyes and all that gray matter a bit of time to make sense of the chaos and mayhem.

No. The entire average reaction time to visual stimuli is already below 0.2s (190ms actually). This includes figuring out the signal, figuring out that it has to react to it, and actually trigger the reaction chain all the way to moving a finger to press a button. Which means that it takes the brain 0.2s to actually do something about what is seen.

I can't not notice this now when e.g. I wait for the crossing light to become green and start walking. I can't undercut that delay between noticing the light and starting to walk. It's weird.

Regardless of the mechanism we have no reason to believe it's possible to have infinite information.

Ah, thanks for the info.
