For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.
We can’t touch objects, ever. Most of the space “occupied” by an atom is emptiness (which is another rabbit hole I’m not willing to go down), and when we “touch” an object, it’s just a force field pushing the atoms apart. It’s the same reason why we don’t fall apart into atoms - some invisible force just really wants our atoms to stay together.
That’s just semantics. For any real definition of “touch”, we do touch objects.
“to put the hand, finger, etc., on or into contact with (something) to feel it”
The electromagnetic fields of your hand come in contact with those of the object, and you feel it.
So how does cutting an apple in half work? The knife must be touching the apple to cut it, right?
You can kind of visualize it as wire EDM manufacturing. Although not a fully accurate depiction, but it fractures the connection between the two sides.
That analogy relies on the reader having any idea what wire EDM manufacturing is. ;) Not exactly an everyday topic.
The apple was never whole… it was simply tightly grouped and a subgroup has been severed from another
And it was severed by a thin slice of atoms that used their force field as a wedge to force them apart.
“So what I’m trying to say, your honor, is that no, I did not inappropriately touch this child”
