What is at the exact centre of an atom?

John Phillips asked the Naked Scientists:
   
What is at the exact centre of an atom? And I don't mean a proton or a neutron.

What do you think?

If bored chemist does not know the answer then just say nobody knows however my own thoughts are that nothing can
exist at the exact centre and I was wondering if or what modern science thought about this

You seem to have missed another possibility; I do know the answer, it's the nucleus and you are just plain wrong.

it is just electrons, quarks and positrons

  electrons(-) + positrons(+) + quark(neutral) →→→→→neutron(neutral)
            
                 positrons(+) + quark(neutral) →→→→→→ proton(+)


  thank you

Not positrons - they are an antimatter particle.
Electrons are in orbit (at a very great relative distance) around the nucleus which contains three quarks.

Consider me, my dad and my brother. At any given time there is a point that is exactly in the middle of the 3 of us- our collective centre of gravity.
Usually there is nothing in particular there. There might be some air, but it's nothing much to do with the 3 of us.

Why do you think here has to be anything special in the middle of an atom?

the question i ask is probably not possible to answer as i suppose you could go on forever dissecting the smallest particle but it is fundemental ,anyway thanks for your efforts
