When sharpening knives, with practice you can tell when you are done by sliding your fingertips along (not across) the sharpened bevel. It's possible to feel imperfections measured in micrometers this way.
If the earth were shrank down to the size of a golf ball, you could feel houses.
That seems wildly unnecessary. I can already feel houses.
I'm sure there's some actual science thing they're referencing here, but I don't understand it. Who can't feel houses?
Both a house and a golf ball are unbelievably tiny compared to the size of the Earth. The idea that you can shrink the Earth many thousands of times over and be able to feel a house parallels with our ability to feel micro imperfections on knife blades.
Oh! As in, should you be an outside observer, and grabbing the whole planet, you'd be able to feel houses on its surface if it were the size of a golf ball?
Presumably you'd feel like crushing under your fingers like the hairs on a kiwi lol
It would be a lot more smoother, smoother than a marble. But thoose detection of micro imperfections might be possible
People without fingers, I guess
