I'll use this answer and tell him that Planck length may be a smallest unit, but distances aren't a fixed number of Planck units and speeds can change less than one Planck length per second. Thanks for helping me out, you guys are great!

Ok, I'll try this: Can something travel less than one Planck length.

I asked him again what he meant. He says that speed cannot change less than one Planck-length per second. I think this is the question I should have asked to begin with.

Hello! My kid asks if this is theoretical idea is correct and I just don't know this stuff very well: It is impossible to travel at light speed but not impossible to travel just below. So the highest theoretical speed should be: "The distance light has traveled in one second" minus "One Planck...

My kid asks questions that I am not sure about how to answer. I'll use this forum as help.
