You have a tiny mustard seed with you. You use a microscope and a very tiny knife and cut it into two halves. You will get a smaller mustard seed.
What if you cut the smaller seed again? You will get an even smaller seed. Can you keep doing this?.
Obviously, at some point, the microscope/knife may not be good enough to cut anymore. But, if you think about it conceptually, what happens if you keep splitting an object into smaller pieces? Let's find out!
