Eli5: How do flies manage to crash into human beings if they can see things at a «slower» pace than us?
In: 0
Hehe, good question…
Flies do see the world in slow motion which helps them react to movement quickly, but they aren’t great at judging distances.
Also, they’re attracted to heat, moisture, and smells from humans. So, they might fly towards us on purpose, but sometimes misjudge and crash into us. Or they could be trying to land on us for those attractive things, and we perceive it as a crash.
