It is said that we can not go lower than the planck limit

[Molari]

Hi. My nephew asked me a good question.

I am trying to understand the Planck limit. It is said that we can not go lower than the Planck limit.
But if we had a an imaginary powerful microscope to see at the plank level, and if we placed 2 Planck end to end with "half" a Planck sized length separating space between the Plancks, does that half a Planck space not conflict with the limit?

Thank you ahead for your time and kindness to give a reply. :)

Kind regards

Thanks, I checked wikipedia before posting but it did not answer my question. :/

What you can see at this distance is a subject of speculation. It is unclear whether the experiment you described is even possible. The wiki article is a good summary.

Would be rather blurred image to inspect

Exactly. Space can't be looked on as made up of Cuisenaire rods. The Planck Length is more of a notional thing than a division on a piece of graph paper.
