Nobody knows how tightly those extra dimensions are curled up,
nobody knows how much smaller than 1mm you have to go before
gravity starts to deviate from the inverse square law, maybe it's
near 10-3 meters but maybe it's nearer to the Planck Length of
1.6*10-34 meters. If you have to get to the Planck Length or even
a million times larger it will probably never be detected
experimentally. And the entire idea might be wrong, there might
not be any extra dimensions at all.

How close do atoms or subatomic particles come to each other when they
collide in particle accelerators? Is the distance between them far
from Planck scale at the moment of collision?
Their preparation doesn't localize them to anywhere near the Planck scale.
