Eli5 what makes it harder to walk on a beam above emptiness then to walk on the street? Only mind trick?
In: 135
A lot would have to do with perspective. Your eyes can perceive the ground around a beam if it’s laying on the ground without having to strain your eyes at all. If you’re fifty feet in the air then when your eyes try to see the ground it’s out of focus because the perspective between the close beam and the far ground is way off and your eyes are constantly changing to try to make the picture work together. Your brain can’t figure out what’s going on and it makes it really hard to balance on the beam in front of you unless you really focus on just the beam and ignore anything else.
