smallest unit of space & time.

Hi All,

I did some search on this group. Someone said
the smallest unit of space is planck length 2x10^-35,
the smallest unit of time is planck time 10^-43.

the max speed should be travel two discret points in smallest time.
these two points should be in continuous, otherwise it will contradict
with the smallest time.

so, the max speed should be 2x10^-35/10^-43 = 2x10^8m/s

but it doesn't consistant with speed of light which is 3x10^8m/s

what is wrong?

Thanks and Regards,
ralph
