Ok, take an apple and cut it in half.
Then take one of the halves and cut it in half...
Then take one of those halves and cut it in half.
Keep doing this, even to the molecular level and beyond...
At what point do you run out of halves to cut? (assuming you have the technology to cut anything, no matter how small).
On one hand, the material can't just dissapear... so you always have something to cut in half.
On the other hand, matter can't be infinite, so you have to run out. Right?
I just love shit that makes my brain hurt
