This a more complicated question than it appears at first glance, because it
depends upon the criterion used to define "small", that is, what is the
instrument of measurement. From a theoretical view, there is a quantity called
the "Planck length" which is the only quantity of "length" that is a combination
of the fundamental constants of nature. Its value is about 1.6 x 10^-35 meters.
Its derivation is a bit involved, so I will not attempt to go into more detail
here. You can refer to:
http://en.wikipedia.org/wiki/Planck_length
for more details. The complication arises because you could counter with -- How
about 1/2 a Planck length?

Greetings!
The smallest possible thing in physics, well in many ways we are still
search for what made and was the origin of the big bang,....this is what
FermiLab and Cern's LHC is about........we are looking for experimental proof
of the Higgs Boson. Hope this helps and gives you some ideas to read about...
this will help answering the smallest entity in physics.
