As has been mentioned in this thread previously, there is no evidence that the Planck length is any kind of limit.

I'll be interested to see this list...

I envision a long stick (really long) that is tied down at one end. If you move the other end of the stick, the atoms in the tied down end must have moved a very small distance. If you made the stick long enough, the distance those atoms would move must approach, or cross, the Planck length.

One way to understand this is to remember that matter is also a wave. For example, how can it be that electrons can only exist in certain orbitals but not in-between, yet they somehow change orbitals.

Consider standing waves like these:

Energy is moving across the nodes of the wave even though the nodes are not moving. Electrons are particles, and also waves.

Does that help?

1) You can't get married to your spouse who is the same sex as you.
2) You can't have an abortion no matter how much you don't want a child.
3) You can't have a certain plant in your possession or you'll get locked up with a rapist and a murderer.

4) We need a smaller, less-intrusive government.
