@BilboGrabbins Hi there!🙋I have a Query, Especially for You.Interested?A_______BA simple line.Start point A.End point B.I suppose i can keep dividing it into Halves.But considering Planck's Length, Can i Divide it until Infinity?If i Know the Line's point of Origin(A) & am Aware of the Line's point of Cessation(B)...Does that sound like Infinity?Or if i didn't know the Origin, n was clueless bout the End.Infinity!Ps - Thanks E_S for the suggestions.I've Realized my capacity to understand & learn is Not infinite.Hence i do not bother myself, & also spare Others of goin thru the troubles of explaining me things which i Firmly Believe i shall never understand.(Reason i Request for short & brief answers, i Hate it when Teachers waste their Precious Time on Futile Things): )

I've Realized my capacity to understand & learn is Not infinite.

No, to divide through the Planck length infinitely many times would be equivalent to a singularity. That is itself equivelent to a breakdown in physics.

...The Planck length is expected to be the shortest measurable distance, since any attempt to investigate the possible existence of shorter distances, by performing higher-energy collisions, would inevitably result in black hole production.... [from Wikipedia]

What prevents us from expanding a 1 meter rod to 1 meter plus half Planck's length, eg. by heating it up?

You can't localise a particle to one point in space unless it's momentum → ∞
